provisions and county-wide policies indicating that cities are the preferred
utility service providers, individual circumstances must always be considered
in determining the optimal service provider. Bellevue's proposed partial
assumption of the Coal Creek Utility District's water and.sewer service area
within the Bellevue city limits will create a situation in which the water and
sewer rates for Coal Creek customers within the cities of Renton and Newcastle
could increase substantially. The Utilities Committee has compared Bellevue's
position and technical data submitted for support with.the District's position
and supporting data,and determined that the proposed partial assumption will
provide no benefit to Renton or Newcastle customers in return for their rate
increase.

Summary of Action: •
The Wastewater Utility has developed an update to our 1992 `Sewer Comp Plan'. The new plan, called the
1998 Long-Range Wastewater Management Plan, is a stand-alone document, not a supplement. We have
completed Administrative Review of the document. We are preparing to make initial submittal to the King
County Utilities Technical Review Committee for their review and to begin the SEPA Process. As part of
these submittals, draft copies will be sent to adjacent utility service providers for their review and comment.
Once we have incorporated the review comments from these processes, we will present the plan to Council
with a recommendation of adoption. Once adopted by Council, the plan would go back to King County for
their approval.
STAFF RECOMMENDATION:
Our first step in this process is to provide the Utilities Committee with a copy of the Summary and
Introduction Chapter and a short briefing on the plan.
H:DIV/UTIL/W W/AB-98PLN/MAB:lf
CHAPTER I
SUMMARY AND INTRODUCTION
A. PURPOSE OF PLAN
The purpose of the Renton Long-Range Wastewater Management Plan (the plan) is to present policy and
design criteria and to recommend facility improvements. This plan will be used as a guide in maintaining
and improving the sanitary sewer system over the next six years in order to provide the Renton Sewer
Service Area with an effective, safe and reliable sewer system. While this plan is an update to the Long-
Range Wastewater Management Plan adopted in 1992; it is a complete re-evaluation of the entire sanitary
sewer system and a stand-alone document, not a supplement. A;summary of this plan's findings and
recommendations are presented in this chapter.
The plan results from an evaluation of the existing sanitary sewer system and recommendations to resolve .
existing deficiencies and concerns, and to accommodate growth. The improvements identified in this plan
are based on the requirements of the Washington State Department of Health,Washington State Department
of Ecology,King County Comprehensive Plan,and City Comprehensive Plan.
The City of Renton adopted its last Long Range Wastewater Management plan in 1992. That plan
anticipated growth in the system and proposed improvements.The plan also attempted to address concerns
for groundwater protection, significant increases in construction cost, and increases in land use densities.
These issues,again,as well as others are examined in detail in this plan.
The Renton sanitary sewer system is large, and because of the topography, complex in its operation. The
condition of the current system, as well as the need for improvements,has been documented in this report.
Due to the complexity of this system and the number of issues that must be addressed, this report is
organized so that a reader may review a summary of it and its recommendations in this chapter without
reading the background or detailed information that led to those results.
The plan provides a recognized framework for making decisions about sanitary sewer service in the City of
Renton and within Renton's Potential Annexation Area. It is intended to aid decision makers as well as
users, including the Wastewater Utility, City Council members, the Mayor and staff, builders, developers,
community groups,and other government agencies. The plan will be a useful tool in the following ways:
• As a framework for improvements and operations that govern sanitary sewer 'system
developments in the Renton wastewater utility service area. The plan provides a basis for
allocating improvements and costs to new sanitary sewer system users such as home and
apartment builders, and commercial developers. It thus provides officials with partial
direction for approving building permits and upgrading the system.
• To provide a guideline for improving the existing system so that each customer receives
adequate sanitary sewer service. It is intended that City officials be able to use these
guidelines to maintain a high quality of service at a reasonable cost.
• To provide a basis for accommodating changes that occur but that cannot be forecast in the
plan. To this end, the plan lists policy issuesand operational criteria that can be used to
develop alternatives and directions for development,improvements and operations.
12/3/98 I-1
CHAPTER ONE
B. NEED TO UPDATE
This update to Renton's Long-Range Wastewater Management Plan is inspired by the need to provide
constant evaluation of our sewer system and operating policies in order to meet the needs of the customers
and to ensure compatibility with the City and County's Comprehensive plans. This updated plan is
prepared in conformance with Chapter 173-240 WAC.
C. SCOPE OF STUDY
The scope of study includes the following:
• Analyze the existing system to determine its deficiencies and needed improvements.
• Document City Council policies regarding growth and service areas.
• Coordinate plan with adjacentutility systems and identify areas for potential service area
boundary adjustments.
• Estimate wastewater flow rates using land use designations.
• Prepare a Capital Improvement Program and estimate its construction costs.
• Document, in summary form, the existing operations and maintenance program and
recommend improvements and staff additions.
• Analyze the recent fmancial performance of the sewer utility and develop a fmancial
operating projection statement.
D. EXISTING SEWER SYSTEM
The City of Renton owns, operates, and maintains its sanitary sewer system. This system consists of
approximately 167 miles of gravity sewer,21 sewage lift stations and force mains, and approximately 3700
manholes. Wastewater is discharged to King County facilities at 67 locations within the City Service Area
from which it is conveyed to and treated by King County's Renton Treatment Plant. The existing sanitary
sewer system is shown on FIGURE 1.
The City of Renton Service Area is divided into seven major wastewater collection basins, each of which
consist of one or more subbasins. These wastewater collection basins are shown on FIGURE 1.
For the most part,these collections basins and subbasins follow the natural drainage patterns of the Renton
service area. For the purposes of this plan, areas that are pumped are included within the basin they are
pumped to. This is a modification from the last plan,where basins were drawn related to topography.
E. POLICIES AND DESIGN CRITERIA
Policies,design criteria, and standards used for planning and operating the sanitary sewer system are based
on laws and policies which originate from several sources All these policies and standards have the general -
purpose of providing an acceptable level of service to the sanitary sewer customers. Policies presented in
this plan include the following: customer service,policies, financial policies, facility-policies, and
1-2 12/3/98
SUMMARY AND INTRODUCTION
organizational policies. Analysis and design criteria for the sanitary sewer system are based on standards
presented in the Criteria for Sewage Works Design prepared by the Washington State Department of
Ecology as well as standards set by King County Department of Natural Resources-Wastewater Treatment
Division and the City of Renton.
F. LAND USE AND ADJACENT SYSTEMS
The land use proposed in the City's 1995 Comprehensive Land Use Plan was used to estimate wastewater
flow ratesat saturation conditions within the City. For portions of the service area outside the current City
Limits, both the County's existing land use and the City's proposed land use were used for evaluation.
These saturation wastewater flow rates were used to analyze existing sewage facilities and to plan for the
location and sizing of new sewage facilities. Existing land use designations are shown on FIGURE 5.
There are several adjacent utility systems surrounding the City's existing service area, which limit the
expansion of the City's sewer system. The greatest potential for expansion of the City's sanitary sewer
system is within the May Valley,Skyway and East Renton areas which currently either do not haveexisting
or adequate sanitary sewer facilities. The adjacent utility entities are shown on FIGURE 7.
G. KEY ISSUES
This plan addresses the following key issues:
• Excessive infiltration and inflow.
• Extension of sanitary sewer service areas.
• Aquifer protection and exfiltration from sanitary sewers. •
• Sewer system deficiencies including hydraulic constraints, substandard facilities, and replacement
of old pipes.
Several of these issues were also addressed during preparations of the1983 Comprehensive Sewer Plan and
again in the 1992 Long-Range Wastewater Management Plan.
H. SYSTEM ANALYSIS
A hydraulic and a structural analysis were conducted to determine how well the existing system achieved
current policies and technical, engineering standards. The plan identifies where:the system failed to meet
those objectives and recommends improvements to the existing system or construction of new facilities to
achieve them.
A hydraulic analysis is a computer simulation of the existing system to determine its ability to convey
wastewater at saturation flow rates. The Wastewater Utility's computer model was used to analyze the
system and to size future facilities. This model was developed for the 1992 Long-Range Wastewater
Management Plan and updated with the 1995 Inflow and Infiltration Study flow monitoring data. This"
computer model will continue to be used by the City as an analytical, planning and management tool. A
structural analysis,which is a visual inspection of the existing system,was also conducted and was based on
video,as well as actual,physical inspections. ____
12/3/98 I-3
CHAPTER ONE
The analysis revealed deficiencies that cover a broad range of areas. The hydraulic deficiencies identified
are inadequate slopes (inability to achieve carrying velocities), insufficient capacity to handle wastewater
flow rates, pipes that are less than 8-inches in diameter and sections that have reverse slopes. Structural
deficiencies identified are pipe sag, and root and grease problems. The Renton sewer system has these
hydraulic and structural problems in varying degrees throughout the system.
I. SEPA
A SEPA Checklist has been prepared for this plan and is presented in Appendix C. It is anticipated that this
proposed plan will not have a probable significant adverse impact on the environment and that an
environmental impact statement(EIS)will not be required. However,many of the projects proposed herein
will require SEPA checklists and some may require an environmental impact statement. •
J. CONCLUSIONS AND RECOMMENDATIONS
In the development of this plan,the following conclusions were reached:
1. A substantial percentage of the system has reached the end of its useful life and needs to be
replaced. The areas of highest concern that should be given highest priority for evaluation
for replacement are: Windsor Hills,North Highlands,South Highlands,Earlington,Renton
Hill,Downtown,Talbot Hill,West Hill,and Sunset(Honeydew).
2 The City needs to continue to perform detailed testing to obtain better engineering
information regarding the operation and hydraulic behavior of the system. Specifically,this
should include a continued investigation for Inflow and Infiltration through flow
monitoring and video inspection.
3. We recommend that the City continue with the policy regarding extension of sewer service:
where the City annexes an area that is currently unsewered by another municipality, the
City should provide sewer service. Where annexation occurs and sewer service is provided
by another municipality, the City should determine whether to purchase the facilities from
the adjacent municipality, or to continue to allow the existing agency to provide service.
Purchase of facilities should be based on the actual depreciated cost the municipality
incurred from providing the facilities to obtain service.
4. The rate increases recommended in this plan should be considered an estimate to
implement the City-funded portion of all the recommended improvements. Currently,new
development pays a major portion of the remaining cost of recommended improvements. If
funding from this source, such as the System Development Charge, is not available, the
City's share of these construction costs will most likely increase. It should also be
recognized that this plan does not establish annual CIP programs or sewer rates, but rather
provides a roadmap and guideline for the operation of the system. Yearly CIP programs
and sewer rates are established as part of the budget process.
5. The City's sewer system is complicated; the preceding conclusions and recommendations
are based on the highest priority issues, which, in our opinion, must be addressed.
However, we propose a substantial number of additional recommended facility
I-4 12/3/98
SUMMARY AND INTRODUCTION
improvements and modifications which are further described in Chapter VI. When we
assigned them priorities,we took into consideration'the following characteristics:
a. Whether a facility is structurally deteriorating or has hydraulic capacity problems.
b. Whether an improvement increases overall efficiency by reducing operation and
maintenance costs.
c. Whether an improvement helps protect the environment or reduces a threat to
public health.
•
K. SYSTEM IMPROVEMENTS
The following is a summary of proposed improvements to the Renton sanitary sewer system, presented in
this Comprehensive Sewer System Plan, to correct existing facility deficiencies and to accommodate
growth.
1. Adopt this Comprehensive Sewer System Plan in order to establish consistent City policies
and to provide the capability of. efficiently planning the sanitary sewer facility
improvements. This plan should be updated at intervals of no greater than six years in
order to accommodate unforeseen changes in existing assumptions and conditions, and for
adjusting budgets and sewer service rates.
2. Replace aging and substandard sanitary sewer facilities within the City. These sewers
present a significant potential danger to the environment and public health.
3. Continue development of the gravity sewer system in order,to allow the elimination of
existing sewage lift stations. These _lift stations are less reliable, require higher
maintenance and operation costs, and cause more adverse impacts to downstream facilities
than do properly planned gravity sewer systems.
4. Rehabilitate or replace the sewage lift stations that are considered to be permanent sewage
facilities. These improvements will reduce maintenance costs and increase system
reliability.
5. Examine programs and projects that will reduce wastewater flow rates and infiltration and
inflow within the sanitary sewer system. These may be cost-effective methods that could
possibly reduce the size of sanitary sewer facilities,thereby reducing capital expenditures.
6. Implement sanitary sewer rate that will adequately fmance capital improvement costs as
well as operation and maintenance costs in accordance with the utility rates study.
L. IMPLEMENTATION
In 1990 the Washington State Legislature enacted the Growth Management Act (ESHB 2929) in order to
preserve the environment and quality of life while providing for economic growth. This act requires cities
and counties in the populated regions of the state to develop coordinated comprehensive plans that will
identify areas where urban growth is appropriate and provide necessary transportation and__utility
12/3/98 I-5
CHAPTER ONE
improvements to them. The adoption of the plan is the Wastewater Utility's on-going fulfillment of the
requirements of the Growth Management Act.
The majority of this document presents information that will be the foundation for the Wastewater Utility
plans for the future of the system. This information includes a general overview of the existing sewer
system and a definition of terms; a presentation of specific policies that guide the management and
operation of the sewer system; an examination of the operation and maintenance programs for the utility;
and a description and analysis of all components in the existing system with recommended improvements.
These items are specifically directed toward the effective and efficient operation of the utility.
The first phase of this plan presents a snapshot of land use under current land use policies. It examines the
current land use plan adopted in 1995, uses those designations to develop the saturation flow rates for the •
model, and establishes an operational plan to allow for the development of those land uses. It is important
that this step be accomplished as any loans or grants we receive will be based on this information.
As part of this process,the Wastewater Utility's goal is to accomplish,pursuant to adoption of this plan,the
following implementation tasks:
A. Update the financial models in a manner consistent with the City's budget schedule, so that
rates can be adopted to accurately reflect the current fmancial situation within the utility.
These models were developed during the development of the 1992 Long-Range
Wastewater Management Plan based upon data provided in the 1989 rate management
analysis (Water and Wastewater Rates Management Analysis, RH2 Engineering P.S,
November 1989). The model was updated as part of the rate study, adopted in 1994
(Comprehensive Rate Study, Water Wastewater, and Surface Water Utilities, Economic and
Engineering Services, Inc.,January 1994).
B. Complete the inventory of the sewer system, verifying the as-built records and gathering
data on those parts of the system that are not recorded.
C. Continue to implement a program to meter flows in order to gather data to calibrate the
sanitary sewer computer model.
D. Use the sewer model to develop a timetable of availability for sewers in unsewered portions
of the City and the Potential Annexation Areas adopted by the City.
E. Prepare an update to the 1998 Long-Range Wastewater Management Plan if necessary, to
incorporate the new adopted land use designations
F. Update the sewer model,if necessary,to reflect the new adopted land use designations and
concurrency standards.
M. HOW TO USE THIS PLAN
This plan is arranged in eight major sections:
Chapter I provides a summary of the recommendations and conclusions presented in this plan.

PUBLIC HEARING This being the date set and proper notices having been posted and
Utility: Sanitary published in accordance with local and State laws, Mayor Clymer opened
Sewer Comprehensive the public hearing to consider the Sanitary Sewer Comprehensive Plan.
Plan Engineering Specialist Mike Benoit reported that the purpose of the plan
is to present policy and design criteria; recommend improvements for
long-range wastewater management; and provide Renton residents with an
effective, safe, and reliable sewer system.
Mr. Benoit stated that the existing City sewer system consists of
approximately 153 miles of gravity sewer and 23 sewage lift stations and
force mains; and that wastewater is discharged to Metro facilities and to
the Metro Treatment Plant in Renton. The City is divided into six major
wastewater collection basins consisting of one or more subbasins that
follow the natural drainage patterns of the Renton service area.
Structural deficiencies in the system include aging sewers, reverse slopes,
sags, root and grease problems, substandard lift stations, and inadequate
capacities.
Mr. Benoit pointed out that the plan addresses excessive infiltration and
inflow, extension of sanitary sewer service areas, aquifer protection and
•
March 9. 1992 Renton City Council Minutes Page 117
exfiltration, sewer system deficiencies, and annexation and service outside
City limits.
Mr. Benoit concluded that the Comprehensive Sewer Plan adopted in 1983
anticipated growth but did not address concerns for groundwater and
aquifer protection, significant increases in construction cost, and increases
in land use densities. He said that the proposed plan is a necessary tool
for use in the planning and operation of the City's wastewater system.
Ray Griffin, 14306 144th SE, Renton, stated his opinion that it is unfair
to require that property owners within 330 feet of an existing sewer line
who chose not to connect to the sewer pay the City's monthly sewer
charge. Mr. Griffin also suggested that "within the City limits" be added
to Policy 1.2.8. for clarification. In response to Mr. Griffin's request for
clarification of Policy 1.3.1, Mr. Benoit indicated that the word
"municipalities" includes water districts.
John Pozega, 3000 NE 4th Street, Renton, supported the Sanitary Sewer
Comprehensive Plan, and urged that pipeline capacity be considered in
improvements to the system to avoid sewer line replacement in the future.
MOVED BY MATHEWS, SECONDED BY EDWARDS, THE PUBLIC
HEARING BE CLOSED. CARRIED.
Referencing Section 3 of the Plan, Councilwoman Mathews noted that
enforcement of the plan was not a Police Department responsibility.
Responding to Councilman Stredicke's inquiry, Mr. Benoit reported that
the City Code requires that all new commercial development have grease
traps or separators, but older development is grandfathered into Code
requirements. He said the City Code limits grease discharges and can
enforce the installment of a grease trap; however, there is insufficient
staff for such enforcement. Mr. Benoit advised that the plan includes a
program to monitor grease trap use.
In response to Councilman Schlitzer's question, Mr. Benoit said that
properties in a new development, with a failing septic system, or in a
Local Improvement District (LID) within 330 feet of an existing sewer
line are required to connect to the sewer system; but if this requirement
is not applicable, the property owner can chose not to connect. However,
those properties must pay the $3.20 monthly sewer charge.
Councilwoman Mathews noted that this charge is required since the
resident would benefit from the sanitary sewer, storm sewer, and related
services.

CITY OF RENTON
COMPREHENSIVE SEWER SYSTEM PLAN
EXECUTIVE SUMMARY
•
•
SUMMARY AND INTRODUCTION
A. PURPOSE OF PLAN
The purposeof the Renton Comprehensive Sewer System Plan is to present policy and design
criteria and to recommend facility improvements. This plan will be used as a guide in
maintaining and improving the sanitary sewer system over the next five years in order to provide
the residents of the City with an effective, safe and reliable sewer system. This plan is not an
update to the Comprehensive Sewer Plan adopted in 1983; it is a complete re-evaluation of the
entire sanitary sewer system. A summary of this plan's findings and recommendations are
presented in this chapter.
The plan results from a study that evaluated the existing sanitary sewer system and developed
recommendations to resolve existing deficiencies and concerns,and to accommodate growth. The
improvements identified in this plan are based on the requirements of the Washington State
Department of Health, Washington State Department of Ecology and City Policy.
The City of Renton adopted its last Comprehensive Sewer Plan in 1983. That plan anticipated
growth in the system and proposed improvements.but did not foresee all of the issues that have
arisensince that time: 1) concerns for groundwater protection, 2) significant increases in
construction cost, and 3) increases in land use densities. These issues and others are examined
in detail in this Comprehensive.Sewer System Plan.
The Renton sanitary sewer system is large, and because of the topography, it is difficult to
comprehend. The condition of the current system, as well as the need for improvements, has
been documented in this report. 'Due to the complexity,of this system and the number of issues
that must be addressed, this report is organized so that a reader may review a summary of it and
its recommendations in this chapter without reading the background or detailed information that
led to those results. .
The plan provides a recognized framework for making decisions about sanitary sewer service in
the City of Renton. It is.intended to aid decision makers as well as users, including the
Wastewater Utility,City Council members, the Mayor and staff, builders,developers,community
groups, and other government agencies. The plan will be a useful tool in the following ways:
• As a'framework for improvements and operations that govern sanitary sewer
system developments in the City's service area. The plan provides a basis for
allocating improvements and costs to new sanitary sewer system users such as
home and apartment builders, and commercial developers. It thus provides City
officials with partial direction for approving building permits and upgrading the
system.
1-1 •
t.
• To provide a guideline for improving the existing system so that each customer
receives adequate sanitary sewer service._ It is intended that City officials be able
to use these guidelines to maintain a high quality of service at a reasonable cost.
• To provide a basis for accommodating changes that occur but that cannot be
forecast in the plan. To this end, the plan lists policy issues and operational
criteria that can be used to develop alternatives and directions for development,
improvements and operations.
Several members of the City staff have a detailed understanding of the City's sanitary sewer
system and have provided valuable input for this plan. Mr. Richard Anderson, Mr. Randall
Parsons, Mr. Mike Benoit,Mr. David Christensen, Mr. Gary Morrison and Mr. Jack Crumley are
thanked for their assistance.
B. AUTHORIZATION
On November 7, 1988, the City of Renton-authorized RH2 Engineering, P. S., to prepare the
:update. to the Comprehensive Sewer System Plan in conformance with the Chapter 173-240
WAC.
C. SCOPE OF STUDY
:The scope of study includes the following:
• Analyze the, existing systemto determine its deficiencies and needed
improvements.
• Document City Council policies regarding growth and annexation.
• . Coordinate plan with adjacent utility systems and,identify areas for potential
service area boundary adjustments.
• Estimate wastewater flow rates using land use designations.
• Prepare a Capital Improvement Program and estimate its construction costs.
• Document, in summary form, the existing operations and maintenance program
and recommend improvements and staff additions.
•' Analyze the recent financial performance of the sewer utility and develop a
financial operating projection statement.

Summary and Introduction
D. EXISTING SEWER SYSTEM
The City of Renton owns, operates, and maintains its sanitary sewer system. This system
consists of approximately 153 miles of gravity sewer, 23 sewage lift stations and force mains,
and approximately 3000 manholes. Wastewater is discharged to METRO facilities at 55 locations
within the City from which it is conveyed to and treated by 1ViETRO's Renton Treatment Plant.
The existing sanitary sewer system is shown on FIGURE 1.
The City of Renton is divided into six major wastewater collection basins, each of which consist
of one or more subbasins. For the most part, these collections basins and subbasins follow the
natural drainage patterns of the Renton service area. These wastewater collections basins are
shown on FIGURE 1.
E. POLICIES AND DESIGN CRITERIA
Policies,design criteria, and standards used for planning'and operating the sanitary sewer system
are based on laws and policies which originate from several sources. All these policies and
standards have the general purpose of providing an acceptable level of service to the sanitary
sewer customers. Policies presented in this plan include the following: customer service policies,
financial policies, facility policies, and organizational policies. Analysis and design criteria for
the sanitary sewer system are based on standards presented in the "Criteria.for Sewage Works
Design" prepared by the Washington State4Department of Ecology as well as- standards set by
the Municipality of Metropolitan Seattle (METRO) and the'City of Renton.
F. LAND USE AND ADJACENT SYSTEMS
Land use proposed in the City's 1983 Comprehensive Land Use Plan was used to estimate
wastewater flow rates at saturation conditions within the City. These saturation wastewater flow
rates were used to analyze existing sewage facilities and to plan for the location and sizing of
new sewage facilities. Existing land use designations are shown on FIGURE 6.
There are several adjacent utility systems surrounding the City's existing service area,which limit
the expansion of the City's sewer system. The greatest potential for expansion of the City's
sanitary sewer system is within the May Creek and East Renton areas which currently either do
not have existing or adequate sanitary sewer facilities. The adjacent utility entities are shown
on FIGURE 7.
1-3
G. KEY ISSUES
This plan addresses the following key issues:
• Excessive infiltration and inflow.
• Extension of sanitary sewer service areas.
• Aquifer protection and exfiltration from sanitary sewers.
• Sewer system deficiencies including hydraulic constraints, substandard facilities, and
replacement of old pipes.
• Annexation and sewer service outside City limits.
Several of these issues were also addressed during preparations of the 1983 Comprehensive
Sewer.Plan.
H. SYSTEM ANALYSIS
A hydraulic and a structural analysis were conducted to determine how well the existing system
achieved current.policies and technical, engineering standards. The plan identifies where the
system failed to meet those objectives•and recommends improvements to the existing system or
construction of new facilities to achieve them.
A hydraulic analysis is a computer simulation of the existing system to determine its ability to
conveywastewater saturation flow_rates. A computer model was developed and used to analyze
the system and to size future facilities. This computer model will continue to be used by the City
as an.analytical, planning and management tool. . A structural analysis, which is a visual
inspection of the existing system, was also conducted and was based on video, as well as actual,
physical inspections.
The analysis revealed deficiencies that cover a broad range of areas. The hydraulic deficiencies
identified are inadequate slopes (inability to achieve carrying velocities), insufficient capacity to
handle wastewater flow rates,pipes that are less than 8-inches in diameter and sections that have
reverse slopes. Structural deficiencies identified are pipe sag, and root and grease problems. The
Renton sewer system has these hydraulic and structural problems in varying degrees throughout
the system.
I. SEPA
A SEPA Checklist has been prepared for this plan and is presented in Appendix E. It is
anticipated that this proposed plan will not have a probable significant adverse impact on the
environment and that an environmental impact statement (EIS) will not be required. However,
1-4
- • • Summary and Introduction
many of the projects proposed herein will require SEPA checklists and some will require an
environmental impact statements.
J. CONCLUSIONS AND RECOMMENDATIONS
In the development of this plan, the following conclusions were reached:
1. Two areas are seriously deficient in capacity: 1) the East Renton area, specifically
the South Highlands, Maplewood, and Heather Downs Subbasins within it,
currently has a moratorium on connections until capacity improvements have been
made, and.2) the Honey Creek Subbasin within the May.Creek Basin is at
capacity and has some marginally reliable facilities.
2. A substantial percentage of the system has reached the end of,its useful life and
needs to be replaced. These areas include the Downtown, North Renton and
Highland areas.
3. The City needs to perform detailed testing to obtain better engineering information
regarding the operation and hydraulic behavior of the system. Specifically, .a
detailed infiltration and inflow project should be performed as well as a video
inspection to affirm this plan's evaluation and provide an improved basis for
future planning.
4. Design and construction standards need to be. modified for use in aquifer
protection areas. We recommend that a zero leakage policy be adopted for sewers
within the Downtown and Maplewood aquifers. A specific example of an
extremely high water quality risk is METRO's Cedar River Interceptor sewer
which currently traverses through the Downtown aquifer. We recommend that this
sewer be relocated so that a failure or leakage is manageable, and contamination
of the City's sole source aquifer is avoided. However, a zero leakage policy
requires a special type of construction which would substantially increase costs
over standard construction costs.
5. We recommend that the City adopt the following policy regarding extension of
sewer service; where the City annexes an area that is currently unsewered by
another municipality, the City should provide sewer service; where annexation
occurs and sewer service is provided by another municipality, the City should
purchase the facilities from the adjacent municipality, based on the actual
depreciated cost the municipality incurred from providing the facilities to obtain
service, so long as those facilities flow by gravity to the City system.
6. The rate increases recommended in this plan should be considered as the
minimum level of increases necessary to implement the City-funded portion of the
recommended improvements. Currently, new development pays a major portion
1-5
of the remaining cost of recommended improvements. If funding from this
source, such as the special utility connecting fee, is not available, the City's share
of these construction costs will most likely increase.
7. The City's sewer system is complicated; the preceding conclusions and
recommendations are based on the highest priority issues, which, in our opinion,
must be confronted. However, we propose a substantial number of additional
recommended facility improvements and modifications which are further described
in Chapter VL When we assigned them priorities, we took into consideration the
following characteristics:
a. Whether a facility is structurally deteriorating or has hydraulic
capacity problems.
b. Whether an improvement increases overall efficiency by reducing
operation and maintenance costs.
c. Whether an improvement helps protect the environment or reduces
a threat to public health.
K. SYSTEM IMPROVEMENTS
The following is a summary of proposed improvements to the Renton sanitary sewer system,
presented in this Comprehensive Sewer System Plan, to correct existing facility deficiencies and
to accommodate growth.
1. Adopt this Comprehensive Sewer System Planinorder to establish consistent City
policies and to provide the capability of efficiently planning the sanitary sewer
facility improvements. This plan•should be updated at intervals of no greater than
five years in order to accommodate unforeseen changes in existing assumptions
and conditions, and for adjusting budgets and sewer service rates.
2. Replace aging and substandard sanitary sewer facilities within the City. These
sewers present a significant potential danger to the environment and public health.
3. Continue development of .the gravity sewer system in order to allow the
elimination of existing sewage lift stations. These lift-stations are less reliable,
require higher maintenance and operation costs, and cause more adverse impacts
to downstream facilities than do properly planned gravity sewer systems.
4. Rehabilitate or replace the sewage lift stations that are considered to be permanent
sewage facilities. These improvements will reduce maintenance costs and increase
system reliability.
1-6
•
• Summary and Introduction
5. Examine programs and projects that will reduce wastewater flow rates and
infiltration and inflow within the sanitary sewer system. These may be cost-
effective methods that could possibly reduce thesize of sanitary sewer facilities,
thereby reducing capital expenditures.
6. Implement sanitary sewer rate increases in order to finance capital improvement
costs as well as operation and maintenance costs in accordance- with the utility
rates study.
L. IMPLEMENTATION
In 1990 the Washington State Legislature, in recognition of the.need for growth management
legislation to preserve the environment and quality of life while providing for economic growth,
enacted the Growth Management Act (ESHB 2929). This act requires cities and counties in the
populated' regions of the state to develop coordinated Comprehensive Plans to identify areas
where urban growth is appropriate, and to provide necessary transportation and utility
improvements. The adoption of the Comprehensive Sewer System Plan is the first step that the
Wastewater Utility is taking to implement the requirements of the Growth-Management Act.
The majority of this document presents information that will be used as a foundation as the City
of Renton's Wastewater Utility plans for the future of the system. This information includes a
general overview of the existing sewer system and a definition of terms; a presentation of specific
policies that guide the management and operation of the sewer system;in examination of the
operation and maintenance programs for the utility; and a description and analysis of all
components in the existing system with recommended improvements. These items are specific
toward the effective-and efficient operation of the utility.
The first phase of the Comprehensive Sewer System Plan is a snapshot in time under current land
use policies. It examines the current land use plan adopted in 1986, uses those designations to
develop the saturation flow rates for the model, and establishes an operational plan to allow for
the development of those land uses. It is important that this step be accomplished as nay loans
or grants we receive will be based on this information.
As part of this process the Wastewater Utility's goal is to accomplish, pursuant to adoption of
this plan; the following implementation tasks:
A. Update the financial models developed in the rate management analysis (Water
and Wastewater Rates Management Analysis, RH2 Engineering P.S, November
1989)during 1992,in a manner consistent with the City's budget schedule, so that
rates can be adjusted to accurately reflect the current financial situation within the
utility.
B. Complete the inventory of the sewer system,.verifying the as-built records and
gathering data on those parts of the system that are not recorded.
1-7
C. Develop and implement a program to meter flows in order to gather data to
calibrate the sanitary sewer computer model.
D. Use the sewer model to develop a timetable of availability for sewers in
unsewered portions of the City and the Urban Growth Areas adopted by the City.
E. Prepare an update to the 1991 Long-Range Wastewater Management Plan if
necessary, to incorporate the new adopted land use designations
F. Update the sewer model, if necessary, to reflect the new adopted land use
designations and concurrency standards.
M. . HOW TO.USE THIS PLAN
This plan is arranged in eight major sections:
Chapter I provides a summary of the recommendations and conclusions presented in this
Comprehensive Sewer System Plan:
Chapter II provides a general overview of,the existing sewer system and a definition of
terms.
Chapter III presents specific policies that,guide the operation of the.sewer system.
Chapter IV. examines the land. use policies that guide how the City of. Renton
accommodates growth; and presents the land uses,joint use agreements and design criteria
that were used to develop wastewater saturation flow rates on which the computer
hydraulic analysis was based.
Chapter V describes and analyzes all components in the existing system and presents their
recommended improvements.
Chapter.VI further describes the improvements necessary to resolve existing deficiencies
and accommodate growth. The proposed improvements are also listed by priority and by
project type.
Chapter VII examines the operation and maintenance programs for the Wastewater Utility.
Chapter VIII presents the costs of the proposed improvements and the,anticipated user
increases which will be necessary to support them.

• The purpose of a wastewater utility is to design, operate and maintain a
sewage collection system that is consistent with the public health and water
quality objectives of the State of Washington. Treatment of sewage,
provided by Metro on a regional basis, is addressed in a Metro prepared
comprehensive plan.
To meet the needs of the wastewater utility and the residents and
businesses of the City of Renton, we have prepared this document to
present policy, system design criteria, maintenance/operation standards and
recommended facility improvements.

2. USE
Thus, this plan will be used as a 6.9.idOni0411t0iiiingatidJitiOrditinti. the
sanitary sewer system in order to provide the residents of the City with an
effective, safe, and reliable sewer system)*
3. MATERIAL COVERED
a. SYSTEM DESCRIPTION and DEFICIENCIES
KRenton's sanitary sewer system consists of approximately:
16lifijiii drainage basins consisting of 4211raili-basins y.
16pniles of sewer pipe
SiOrlOjmanholes
r.20-Ni stations
Collecting and transporting sewage via Metro trunk lines to the
regional treatment plant.
Our system services approximately 74/%Rib1diitIOAWAho
ppplikatjOYthrough more than IgA00diiitiiiff01 connections. The
remainder of the City is either undeveloped or served by private on-
site septic systems. , '•
e 4
Our system utilizes,a variety of pipe sizes ranging from 6 inch to 24
inch. Typically, 6-inch pipe is old and below current standards while
those pipes 10 inches and above are the interceptors or trunk lines.
The pipe materials used are Concrete, PVC, CLAY, and ductile iron.

b. LEVEL OF SERVICE
By defining the flow:criteriaiand design:,criteriia`in chapter four, we
have identified a level of service that we must maintain for the
benefit of the residents of the city and set criteria that must be met
by future development.
c. SEWER SYSTEM POLICIES
Chapter three pocumenfs, in one place, the ith i1ant policiesxthat are
used in the operation of the Wastewater Utility. This overview and
references to pertinent codes and laws makes it easier for citizens,
staff, and developers to be aware of how we conduct the business of
• providing sewer service and what our requirements are.
The policies cover 1) Funk#0, service, including annexations, land
use, aquifer protection and planning criteria; 2) 4nance4ncluding
user fees and rates; 3)-mil t es including design criteria,
maintenance, reliability; and 4) or..'g lii0lional structure.
This plan was developed consistent with the existing and proposed
land use plans. As land use plans are updated, we will review the
wastewater plan for compatibility and update as necessary.
This plan is consistent with the Water Comprehensive Plan identifying
policies and ranking criteria pertinent to the aquifer.
d. CAPITAL IMPROVEMENT PROGRAM
•
1) PROPOSED IN PLAN
The primary goal and objectives of the Capital Improvement
Program, recommended in Chapter 6, is the replacement=aiic. r
reliabi)itation of the existing sewer system and the gliiriinat'ion
of-lift°stafioris to meet and maintain our level of service.
This plan provides to ik ing e itenWfor Capital Improvement
Projects and a list of proposed projects ranked with this
criteria. This section is required for future work that involves
grants, loans, or franchises. This list should be considered
nothing more than a list of projects that the Wastewater Utility
foresees being necessary in the next 20 years.
2) PROPOSED ANNUALLY AS PART OF BUDGET
PROCESS
Staff will continue our policy of ,annuagyi;°,presenting a:new5°-
earl Capital Improvement Program to Council as part of the
budget process. The adopted plan will be used as a guide in
the preparation of the annual CIP. Staff will prioritize projects
by the given criteria including coordination with other Capital
Improvement Programs (i.e. Transportation, Water,
Stormwater).
e. MAINTENANCE AND OPERATIONS
•
Chapter 7 discusses the Wastewater Utility's maintenance and
operations, detailig .our cu'r"rent;program'and staff and makes
iecommelgAt ons on how the program can be strengthened by
altering the methods we use and staffing we have to run the
utility.
D. SUMMARY & CONCLUSION
The City of Renton adopted its last Comprehensive Sewer Plan in
1983. That plan anticipated growth in the system and proposed
improvements but did not foresee all of the issues that have arisen
since that time:
1) Concerns for groundwater and aquifer protection;
•
2) significant increases in construction cost; and
3) increases in land use densities.
This plan provides a recognized framework for making decisions
about sanitary sewer service in the City of Renton. It is intended to
aid decision makers as well as users, including the Wastewater
Utility, City Council members, The Mayor and staff, builders,
developers, community groups, and other government agencies.
Providing sanitary sewer service is not cheap. We must plan wisely
and use our funds efficiently. We need to develop a sewer system
that will stand the test of time and avoid costly duplication of
projects. This document will be an important tool for guiding the
utility for the planning and operation of the City's wastewater
system.

SUBJECT: SANITARY SEWER COMPREHENSIVE PLAN
We are preparing to take the Sewer Comprehensive Plan to City Council for final
approval. To accomplish this goal, we are proposing the following actions:
March 5 Brief the Utilities Committee on the changes made to the plan
and the presentation we will make for the public hearing.
March 9 Hold the public hearing. Staff will give a brief presentation, take
questions and comments from the Council, and open the floor for
comments from the audience. Comments will be addressed in a
report to Council through the Utilities Committee.
March 19 Report to the Utilities Committee and address the questions and
comments from the public hearing.
We are providing you with a set of insert pages for the revisions made subsequent to
the reviews by adjacent districts and as part of the SEPA process. Please replace the
appropriate pages in Chapters 3 and 4. The format of Chapter 3 has changed so it has
been rewritten. In Chapter 4, we have inserted additional text. For Chapter 4, the
additions are marked by vertical "edit" bars in the margin.
February 27, 1992
Page 2
You may also notice that, with these revisions, we are beginning a transition from
calling this document a "Comprehensive Plan" to the new title of "Long-Range
Wastewater Management Plan". This decision was reached in an attempt to alleviate
the confusion over titles we have noted when dealing with the review of the plan.
This document is one element (as is the Water Plan, Land Use Plan, etc.) of the City's
Comprehensive Plan.

CHAPTER III
OPERATIONAL POLICIES
A. INTRODUCTION
The existing sewer system is designed and operated according to specific ordinances, regulations
and engineering standards (hereafter collectively referred to as policies). All of the policies
originate from seven sources, listed in descending order, from those with the broadest authority
to those with the most narrow:
• Federal Regulations - Environmental Protection Agency
• State Regulations - Department of Ecology
• METRO Policies - Municipality of Metropolitan Seattle
• City of Renton Ordinances - City Council
• Administrative Policies - Mayor
• Department Policies - Public Works Department
• Long-Range Wastewater Utility Policies - Wastewater Utility Staff
Federal regulations, state regulations, METRO policies, and City of Renton ordinances dictate
requirements that are set by law. Policies that originate in the Office of the Mayor,Public Works
Department, or Wastewater Utility cannot be less stringent or in conflict with the laws above
them.
This chapter defines the long-range wastewater policies that will become the official policy of
the Wastewater Utility when the City Council adopts this plan. This chapter also summarizes
relevant federal, state and city ordinances and laws. Where these policies are further developed
in other chapters in this plan, the chapter number is indicated.
All of the policies guide the Wastewater Utility's daily operations as well as its planning
activities. The policies overall goal is to provide adequate, reliable sanitary sewer service at a
minimum cost to the customer. This broad service goal consists of four more narrowly defined
goals:
1. Customer Service
2. Financial • •
3. Facilities
4. Organization

B. WASTEWATER UTILITIES POLICIES
The long-range wastewater policies are presented in their entirety below; the chapters which
present how they will be implemented are also indicated. City and state ordinances and laws are
summarized below; for their actual wording, please refer to the indicated sources. The policies
presented here will become the official policies of the Wastewater Utility when the City Council
adopts this plan. Consequently, they are presented in the traditional policy format rather than the
outline format that the other chapters follow.
1.0.0 CUSTOMER SERVICE GOAL: Ensure the availability of an adequate level of sanitary
sewer service which is consistent with land use,environmental protection, and annexation
goals and policies.
1.1.0 ANNEXATION OBJECTIVES: Ensure the availability of an adequate level of sanitary
sewer service to areas annexing to the City.
POLICIES:
1.1.1 (RCW 35A.14 and RCW 35.13A)
City annexation policies will not conflict with adopted state regulations and guidelines. The City
of Renton will follow state guidelines that define a City's ability to assume facilities in
annexation areas.
1.1.2 (RCW 35.13A.050)
Areas annexed without existing municipal sanitary sewer service shall be served by Renton unless
a service agreement exists or is negotiated with a neighboring utility.
1.1.3 (RCW 35.13A and Long-Range Wastewater Management Plan, Chapter 4)
Areas annexed with existing sanitary sewer service must meet the City's sanitary sewer service
objectives as defined in Section 1.2.0. Upgrading to City standards of sanitary sewer facilities
within all or portions of newly-annexed areas will be required if there is a threat to public health
and safety. If improvements are necessary, they may be accomplished by developer installation
or LID as a condition of the annexation.

The City Council will consider and may allow sanitary sewer service to properties outside the
City's corporate limits when no other reasonable service is available and it is in the City's best
interest. Consideration will be given to the following factors:
a) The applicant is a municipal or quasi-municipal corporation, such as a school,
hospital or fire district, County of King, or similar public entity.
b) Service is necessary to convert from a failing or failed septic system, and the
property owner executes an agreement by which the owners,their heirs, successors
or assigns, agree and covenant to sign a petition to annex the property into the
City of Renton.
c) Service is necessary to protect the City's drinking water supplies.
d) The property to be served is within a drainage basin where service can be
provided with gravity flow via the existing Renton sewer system; the property is
• not within another sewer service district that has service available through existing
or gravity extension of existing facilities; and the property owner executes an
agreement by which the owners, their heirs, successors or assigns, agree and
covenant to sign a petition to annex the property into the City of Renton.
1.1.6 (1992 Long-Range Wastewater Management Plan, Chapter 4)
The City Council shall consider annexations without assumptions of existing sanitary sewer
facilities under the following conditions:
a) The sanitary sewer facilities are or will be operated and maintained by an adjacent
municipal utility; and
b) The adjacent utility has executed a service boundary agreement with the City; and
c) The annexation area is better served by the adjacent utility because either due to
a drainage basin or to the most logical extension of facilities.

Land Use Policies/Adjacent Systems/Design Criteria
The existing land use pattern of the City of Renton reflects 100 years of settlement and
expansion. The original City was settled in the broad floodplain at the confluence of the Cedar
and Black Rivers along the shore of Lake Washington. This area continues to be the heart of
Renton; its industrial uses, the airport along Lake Washington and the Central Business District
at the foot of Renton Hills are interspersed with older, single-family housing and small apartment
complexes.
Residential areas were the hills and plateaus surrounding the core area originally developed in
the county and annexed to the City. Single-family residential neighborhoods are concentrated
in the Highlands, Kennydale Hill, West Hill, Earlington Hill, Talbot Hill, and the ridges along
Maple Valley.
Along the edges of the single-family neighborhoods and the transportation corridors are
concentrations of multi-family housing. Significant concentrations exist along NE 4th Street,NE
Sunset Boulevard, SW Sunset Boulevard, and Benson Road So.
In addition to the central business district, commercial areas are concentrated along the major
arterials and freeway exchanges, including Rainier Avenue, Grady Way, Sunset Highway,
Bronson Avenue, NE 4th Street, the NE 44th Street exit, and SW 43rd Street.
The Green River Valley was annexed to Renton in the late 1950s with the intention of developing
a second industrial base. This area, which was originally the northern end of a long farming belt
along the Green River, now includes a few residual houses and a significant concentration of
manufacturing, warehousing, and office park development. A hub of commercial services is
located in the southeast corner of the City limits.
Valley Medical Center dominates the land uses along the southern portion of Talbot Hill.
Surrounding the hospital is a concentration of support facilities, including medical and dental
offices and laboratories.
Parks in the Renton area tend to be located along river channels and lake shores. Many parks
are located along the Cedar River, including: Liberty Park, Maplewood Golf Course, Cedar
River Park, Jones Park, and the Cedar River Trail. Gene Coulon Memorial Beach Park and
Kennydale Beach Park are situated directly on the shore of Lake Washington.
The City is currently bounded in the south and west by Kent and Tukwila, and to the north by
Lake Washington. Future land use is primarily a function of the location of existing vacant land
within the City and the rezoning of existing designations. The zoning designations for the vacant
land within the City are listed in TABLE IV-4.
4-7
CHAPTER FOUR
2. AQUIFER PROTECTION ORDINANCE
The City of Renton drafted an Aquifer Protection Ordinance to protect its water supply from
being contaminated, which is scheduled to be adopted in 1992. Once the ordinance is adopted,
it will regulate land use within two specified zones in order to protect the aquifer from
contamination. Although the City has not yet adopted the ordinance, it has adopted an aquifer
protection area (APA), which is that area within the zone of capture for the City's aquifers and
spring. The APA is divided into two zones. Zone 1 is that area in which contamination would
reach the aquifer within a year. Zone 2 is that defined as the remaining area within the APA that
is within capture area for the City's water supply wells.
Land use in Zone 1 will be more strictly regulated than in Zone 2. All new development within
Zones 1 must connect to the sewer system. Existing development must connect if it is within
330 feet of a sewer line. In Zone 2, all new platted single-family, multi-family and commercial
development must connect to the sewer system. However, a single-family residence is required
to connect only if it is within 330 feet of a sewer line. Existing development in Zone 2 that is
within 330 feet of a sewer line must connect to the sewer system within either 12 months of the
ordinance passing, or the availability of a new sewer line. A more detailed description of the
proposed aquifer protection policies can be found in Chapter 3.
3. UNINCORPORATED KING COUNTY
Land use within the unincorporated portions of the study area is controlled by the 1985 King
County Comprehensive Plan. All of the study area in unincorporated King County is designated
"urban." Urban areas are those areas where most new housing and jobs will be located and
where most public spending for facilities, services, and open space is normally focused.
Comprehensive Plan Policies R-201 and R-202 establish a goal of achieving an average density
of seven to eight dwelling units per acre within the urban area. Such an overall density goal
cannot be achieved without providing sanitary sewer service to residential development.
King County is divided into smaller planning areas called Community Planning Areas. Two
community plans, Newcastle and Soos Creek, cover most of the unincorporated areas within the
study area of this Plan. The Soos Creek Community Plan was adopted in November 1979 and
is currently in the process of being updated. According to County staff, it is expected that a
revised Soos Creek Community Plan will be forwarded to the King County Council for review
and adoption in 1991. The Newcastle Community Plan was adopted in 1983. The update
process for the Newcastle Community Plan has not been scheduled.

4. ANNEXATION
When areas outside of the city limits annex to the City, they must be provided with an adequate
level of sewer service. Annexed areas that do not have sewer service will be served by the City
of Renton unless another utility has agreed to serve the area. Annexed areas with existing
sanitary sewer service must meet the City's sanitary sewer service objectives as they are defined
in Section 1.2.0 in Chapter 3. However, upgrading sanitary sewer facilities to all City sanitary
sewer standards will be required only if there is a threat to public health and safety. As a
condition of the annexation, improvements may be required, which can be constructed by
developer installation or Local Improvement District (LID). A more detailed description of the
City's annexation policies can be found in Chapter 3.
5. SPHERE OF INFLUENCE
The City of Renton has entered into an interlocal agreement with the Cities of Bellevue and
Issaquah to establish sphere of influence lines. This agreement was signed by the three
jurisdictions in 1979. The sphere of influence agreement places responsibility for long-range
planning with the City of Renton within its sphere of influence
6. ADJACENT UTILITY SYSTEMS/JOINT USE AND SERVICE AGREEMENTS
The City has entered into several joint use and service agreements with neighboring districts and
private customers when it has been economically beneficial. A list and a summary of these joint
use and service agreements is presented below. The full text for each of these agreements is
presented in Appendix B.
• The Tiffany Park Interceptor Joint Use Agreement with the Soos Creek Water and Sewer
District.
• Apollo School Lift Station Service Agreement with King County Water District 90.
• Earlington Elementary School Service Agreement.
• King County Water District No. 107 Utility Franchise Agreement.
• King County Water District No. 107 Joint Use Agreement.
• . King County Sewer and Drainage District No. 4 Agreement.
• City of Kent Agreement.
• Cascade Sewer District Service Boundary Agreement.
• Bellevue/Issaquah/Renton Sphere of Influence Agreement
The City is surrounded by eight adjoining utility entities, seven of which provide sanitary sewer
services. These eight utility entities are shown on FIGURE 7. It is evident that some sewer
franchise boundaries overlap with the City limits. These areas are also shown in FIGURE 7.
4-9
CHAPTER FOUR
The study area for the City's Comprehensive Sewer Plan is shown on FIGURE 5. It includes
parts of drainage basins within adjoining utility entities. Areas which may be considered for
service boundary adjustments are also shown in FIGURE 5.
a. KING COUNTY WATER DISTRICT NO. 107
King County Water District No. 107 provides sewer service in part of the May Creek
Basin. The District adopted a Comprehensive Sewer Plan in 1988. Its plan for serving
May Creek Basin includes diverting approximately 1,000 acres from the May Creek Basin
to the Coal Creek Basin on an interim basis. This plan is based upon two assumptions:
first, that it would be too difficult and expensive to construct a May Valley Interceptor
at this time, and second, that the City of Renton's service in the southern part of the
Basin is adequately provided by the Honey Creek Interceptor. In order to accomplish this
diversion, the District is proposing to construct three lift stations and to complete a Coal
Creek Interceptor Improvement Project.
The sewer franchise boundary for King County Water District No. 107 is shown on
FIGURE 7. Two small service area overlaps occur because the City annexed part of the
District, but the District has not yet redrawn its boundaries.
The District and the City have entered into joint use agreements in the past in order to
provide for the construction of sanitary sewer facilities. Joint use agreements will
continue to be needed as the May Creek Basin develops. The existing service area gap
which is located south of May Creek and east of Honey Creek may best be served by the
City. This service area gap is shown on FIGURE 5.
b. • KING COUNTY WATER DISTRICT NO. 90
King County Water District No. 90 does not currently provide sanitary sewer service.
However, the District does have a sewer franchise boundary which is shown on FIGURE
7. The District had a Comprehensive Sewer Plan prepared in 1970, but has not proceeded
with the formation of a sewer district due to opposition from the community.
Since the District is reluctant to provide sewer service within its franchise boundaries,the
Cityis experiencing annexation pressures from property owners adjacent to the City limits.
These annexation requests are forthe purpose of obtaining sewer service. For this reason
and due to natural drainage patterns, the study area shown on FIGURE 5 extends outside
the current City limits.
4-10
Land Use Policies/Adjacent Systems/Design Criteria
c. CEDAR RIVER WATER AND SEWER DISTRICT
Cedar River Water and Sewer District provides service to parts of the Lower Cedar River
Basin. However, only a small fraction of the wastewater from Cedar River Water and
Sewer District ultimately flows through the City of Renton's system by flowing through
the Soos Creek Water and Sewer District. The majority of sewage from Cedar River
Water and Sewer District flows directly into METRO's Cedar River Interceptor located
along the Maple Valley Highway. The District's last Comprehensive Sewer Plan was
adopted in 1983. According to the District's engineer, a revised Sewer Plan for Cedar
River Water and Sewer District is expected in 1991.
The sewer franchise boundary for Cedar River Water and Sewer District is shown on
FIGURE 7. A service area overlap occurs as a result of the City's recent annexation of
the park area located east of the Maplewood Golf Course. Currently, no sewage facilities
are required; the City will provide these services.
The Wasmeta Park area is a service area gap between the City and the District. Currently
no sanitary sewer facilities exist within this area. If sewer service is needed or required,
the City should provide it because it is on the north side of the Cedar River, and the
remaining service area of the Cedar River Water and Sewer District is on the south side.
d. SOOS CREEK WATER AND SEWER DISTRICT
Soos Creek Water and Sewer District adopted a Comprehensive Plan in 1987. The plan
acknowledges several service area overlaps with the City of Renton. The District also
proposes providing sewer service within portions of the Black River Basin within the City
of Renton.
Renton has an agreement with Soos Creek Water and Sewer District for joint use of a
sewer interceptor in the Tiffany Park Subbasin, and for joint use of the Springbrook
Interceptor,located on So. 192nd Street. The Springbrook Interceptor will provide service
to the southernmost portions of the City of Renton.
The sewer franchise boundary for Soos Creek Water and Sewer District is shown on
FIGURE 7. Several service area overlaps occur because the City and the District are
currently negotiating revisions to the service area boundaries between them. These
proposed revisions are shown on FIGURE 5. This agreement proposes that the City
serve some areas outside the City limits, and that the District serve some areas inside the
City limits.
4-11
CHAPTER FOUR
e. CITY OF KENT
SW 43rd Street is the principal dividing line between the cities of Renton and Kent.
Renton has an agreement with Kent to serve a small area south of SW 43rd Street east
of 72nd Avenue So. and west of the Puget Sound Electric Railway right-of-way. The
City of Kent Comprehensive Sewer Plan was adopted in 1980. The Renton and Kent
City limits adjoin each other as shown on FIGURE 7, and there are no service area
overlaps or gaps between the two entities, except for that one small area.
f. CITY OF TUKWILA
A portion of the City of Tukwila east of the Burlington Northern Railroad and south of
Longacres is served by the City of Renton. Tukwila also discharges from a lift station
into the METRO Sewer System within the City of Renton along SW 10th Street.
Tukwila prepared a Comprehensive Sewer Plan in 1984. This Plan shows the extension
of sanitary sewer service by the City of Tukwila into the City of Renton in the vicinity
of Longview Avenue So. and SW 33rd, ultimately connecting into the existing Renton
system along the railroad right-of-way. The 1984 Tukwila Plan also shows relocating two
sewer mains north of I-405 in the vicinity of 72nd Avenue So. and SW 10th Street within
the City of Renton in order to eliminate a pump station within the City of Tukwila.
The Renton and Tukwila City limits adjoin each other as shown on FIGURE 7.
However, a natural service area boundary between the two entities is the Green River,
which might be considered for a service area adjustment as shown on FIGURE 5.
g. SKYWAY WATER AND SEWER DISTRICT
A copy of the 1984 Comprehensive Sewer Plan for Skyway Water and Sewer District was
obtained from the District's engineer. The Plan appears to be a compilation of previous
plans that were done for King County and the predecessor to Skyway Water and Sewer
District. It appears, however, that no facilities within the Skyway service area directly
discharge to, or would affect, facilities within the Renton sewer system.
The Skyway Water and Sewer District does not have a sewer franchise boundary
according to records provided by King County. However, the franchise boundary may
still be under the former King County Sewer and Drainage District No. 4. The service
area from the District's Comprehensive Sewer Plan is shown on FIGURE 7.
Approximately 60 percent of the District is served with sanitary sewer facilities. A large
area within the District, as well as in the service area gap to the south of the District,
could be served by gravity to the Renton sanitary sewer system. This area is shown on
FIGURE 5.
4-12
Land Use Policies/Adjacent Systems/Design Criteria
h. BRYN MAWR-LAKERIDGE WATER AND SEWER DISTRICT
According to maps provided by the District, Bryn Mawr-Lakeridge Water and Sewer
District serves a small area of Renton along Rainier Avenue near So. 117th Place.
Sewage from Bryn Mawr/Lakeridge discharges into the METRO System within the City
of Renton at the north end of the Renton Airport.
The sewer franchise boundary for Bryn Mawr-Lakeridge Water and Sewer District is
shown on FIGURE 7. The eastern part of the District could be served by gravity to the
Renton system. This area is shown on FIGURE 5. However, unless this area is annexed
to the City, there is no advantage to this service area transfer.
D. ANALYSIS AND DESIGN CRITERIA
This section presents the design criteria for sanitary sewage collection system analysis and design. •
Analysis is necessary to determine the adequacy of the existing system and to identify needs for
future facilities. The analysis and design criteria are based on "Criteria For Sewerage Works
Design" prepared by the Washington State Department of Ecology, the Municipality of
Metropolitan of Seattle (METRO), the City of Renton Standards, actual water usage records, and
other accepted engineering criteria and standards for sanitary sewer design and construction.
1. WASTEWATER FLOW RATES - DEFINITION
Wastewater in the service area is generated by the population and by non-residential users within
it. The Renton Comprehensive Land Use Plan identifies eleven, separate land use categories.
For sanitary sewer planning purposes, these eleven categories were used to determine wastewater
flow rates for the hydraulic computer model. The eleven land use categories are listed in
TABLE IV-3.
Eleven saturation land use populations were determined by calculating the areas of each
designated land use category. This was accomplished by assigning land use designations to all
parcels within a land use boundary on a computer base map that was used for producing the
figures for this plan. Saturation was defined as the point at which development is complete
within a land use designation.
2. WASTEWATER FLOW CRITERIA
Wastewater flows can be divided into four major components, which are 1) domestic wastes, 2)
industrial wastewater, 3) infiltration, and 4) inflow. The wastewater flow criteria used for each
or these four components is presented in TABLE IV-5.
4-13
CHAPTER FOUR
a. DOMESTIC WASTEWATER
Domestic wastewater flows are essentially equal to winter-time water consumption and
are are typically established on a per capita basis. The average domestic wastewater flow
• used for analysis and design of the sanitary sewer system is 80 gallons per day per
person.
b. COMMERCIAL/INDUSTRIAL WASTEWATER
Commercial and industrial wastewater is defined as the wastewater generated from a
specific commercial or industrial operation. Commercial and industrial wastewater does
not include waste generated by employees of the industry, which is considered domestic
waste and excluded from this category.
c. INFILTRATION •
Infiltration is the entrance of groundwater into the sanitary sewer system through cracks,
pores, breaks, and defective joints in the sewer piping network. Additional infiltration
also results from the entrance of storm- water through manhole covers. The quantity of
water that may infiltrate into a sanitary sewer system depends upon many variables, such
as the age of the system, materials used in construction, and the service area's hydrology,
soils and groundwater level. However, the design of the sewer system, including mains,
laterals, and individual connections, along with inspection during construction, will have
substantial impact on the quantity of infiltration.
Due to improvements in construction materials and practices, systems installed after 1960
generally show a decrease in the quantity of groundwater infiltration. The use of non-
porous piping materials and rubber-gasketed type joints will help reduce infiltration and
will improve the condition and life of the sanitary sewer system. The design allowance
for infiltration is shown in TABLE IV-5.
d. INFLOW
Inflow refers to direct flows of stormwater into sanitary sewer systems through hookups
from stormwater collection facilities and illegal connections. Stormwater inflow is due
mainly to unauthorized connections to the sanitary sewer system. The enforcement of
regulations banning the illegal connections to the sanitary sewer system along with
continued efforts to identify and correct previously unauthorized connections minimize
stormwater inflow. The design allowance for stormwater inflow is shown in TABLE IV-
5.

3. SANITARY SEWER DESIGN CRITERIA
All sewer lines within the City of Renton shall be designed in accordance with good engineering
practice by a professional engineer with minimum design criteria presented in Chapter 2 of the
"Criteria for Sewerage Works Design," prepared by the State of Washington Department of
Ecology,October 1985,or as superseded by subsequent updates. This chapter includes standards
and guidelines for design considerations (minimum pipe sizes, pipe slopes and wastewater
velocities),maintenance considerations,estimating wastewater flow rates,manhole locations,leak
testing and separation from water pipelines. These criteria have been established to ensure that
the sanitary sewers convey the sewage and protect the public health and the environment. The
sewer lines shall also conform to the latest City of Renton Standards and Specifications. Detailed
standards are included in Title 8, Chapter 5 of the City Code which is presented in Appendix D.
Requirements relating to design are listed below.
a. DESIGN LOADING FOR SANITARY SEWER FACILITIES
Sanitary sewer system flows are composed of residential, institutional, commercial, and
industrial sewage, along with infiltration and stormwater inflow. Sanitary sewer systems
must be capable of conveying the ultimate peak flows of these wastewater sources. No
overflows shall be permitted.
b. DESIGN PERIOD
The design period is the length of time that a given facility will provide safe, adequate
and reliable service. The period selected for a given facility is based on its economic life,
which is determined by the following factors: the structural integrity of the facility, rate
of degradation,cost of replacing the facility,cost of increasing the capacity of the facility,
and the projected population growth rate serviced by the facility. Collection and
interceptor sewers are designed for the ultimate development of the contributing area.
The life expectancy for new sanitary sewers, using current design practices, is in excess
of fifty years.
c. DESIGN OF SANITARY SEWER FACILITIES
Allowable sewer pipe shall be ductile iron, cast iron, PVC, or concrete. For normal
depth, PVC is generally preferable, because it has longer laying lengths, which results in
fewer joints, reducing the potential for infiltration.
Gravity sewers are sized to provide capacity for peak, wet-weather flows. The smallest
diameter sewer allowed is 8-inches. All sewers will be laid on a grade to produce a mean
velocity when flowing half-full of at least 2 feet per second. Manholes will be at least
4-16
Land Use Policies/Adjacent Systems/Design Criteria
48-inches in diameter and will be spaced at intervals not to exceed 400 feet on sewer
lines 15-inches in diameter or less, and 500 feet on sewer lines 18-inches in diameter or
larger. The design parameters are summarized in TABLE IV-6.
d. ROUGHNESS COEFFICIENT
The Manning equation shall be used to design and analyze wastewater flow characteristics
of the sanitary sewers. The Manning roughness constant [n] shall vary depending on the
pipe material. Typical values are summarized in TABLE IV-6.
e. REFERENCE DATUM
The King County Aerial Survey (K.C.A.S.) is the common datum used within the City
of Renton for design and construction of sanitary sewer facilities.
f. SEPARATION BETWEEN SANITARY AND OTHER FACILITIES
The Department of Ecology requires separation of water and sewer facilities for health
reasons. Sanitary and storm sewer facilities shall have basic separation requirements for
construction purposes. A minimum horizontal separation of five (5)feet between sanitary
and other facilities shall be maintained. Wherever possible, a horizontal separation of
seven (7) feet is desirable. These distances are measured edge to edge.
g. HYDRAULIC ANALYSIS
The sanitary sewer system hydraulic analyses will be performed using the City's hydraulic
computer model. All new developments, with the exception of developments involving
less than five single-family residences, will require an analysis. The developer shall be
responsible for paying the cost of the analysis of the sanitary sewer system. If the
analysis concludes improvements need to be made, the developer and the City may need
to negotiate about who will pay the costs.
4. LIFT STATION DESIGN CRITERIA
Sewage lift stations within the City of Renton shall be designed in accordance with good
engineering practice by a professional engineer using the minimum design criteria presented in
Chapter 3 of the "Criteria For Sewerage Works Design," prepared by the Washington State
Department of Ecology,October 1985,or any subsequent updates,and shall conform to the latest
City of Renton standards and specifications. Detailed standards are included in Title 8, Chapter
5 of the City Code, which are presented in Appendix D. Requirements relating to the design are
listed below.

a. DESIGN LOADING FOR LIFT STATIONS
Lift stations shall be designed to handle the peak, wet-weather flow from the contributing
area. All lift stations shall have a minimum of two pump units, each with the capacity
to handle the expected maximum flow.
4-18
Land Use Policies/Adjacent Systems/Design Criteria
b. DESIGN PERIOD
The design period for lift stations shall take into consideration long-term needs,
replacement or expansion difficulties, service area growth rate and useful life. A lift
station should have a minimum design period of twenty years for the facility and ten
years for mechanical and electrical equipment. Consideration should be given to longer
design periods for lift stations that are expected to serve an indefinite life. Consideration
must also be given to the ability of the consumers to pay for the facilities.
c. DESIGN OF LIFT STATION FACILITIES
Lift stations shall be designed with a minimum of two pumps, both of which have the
capacity to convey peak, wastewater flow rates. If wide variations in wastewater flow
rates are expected into the lift station, then consideration should be given to the use of
three or more pumping units. If three pumps are used, two of them must have the
capacity to convey peak, wastewater flow rates. Each pump shall be capable of passing
spheres of at least 3-inches in diameter. .,
Each lift station will be provided with either an on-site or portable power backup. A lift
station designed for portable power backup will be provided with sufficient wet-well
storage to allow adequate time for City maintenance personnel to transport, setup, and
provide the necessary backup, during a power outage. Wet-well storage will be designed
on the basis of the peak, wet-weather flow.
Force mains shall be sized to maintain a minimum velocity of 2 feet per second. The
force main shall have a maximum velocity of 10 feet per second when all pumps are
operating together. Regardless of these velocity criteria, minimum size shall be 4-inches
in diameter.
5. ELIMINATION OF LIFT STATION FACILITIES
Lift station facilities are typically eliminated through the development of the gravity sewer
system. Highest priority should be given to elimination of lift station facilities because of their
high degree of vulnerability and high operation and maintenance costs. These considerations
include environmental risks, life-cycle costs, lift station impacts on downstream sanitary sewer
facilities, vulnerability to vandalism, and lift station accessibility.

February 24, 1992 Renton City Council Minutes Page 88
Mr. Fawcett said that since all properties benefit from the existence of
wetlands, every citizen is responsible for their preservation; and suggested
that it would be more equitable if the City required that all new
commercial, industrial, residential, and public development purchase
existing or create new wetlands.
Citizen Comment: Ruth Brandal, 1309 Sunnyside Blvd., Everett, 98205, requested that the
Brandal - Notification City notify non-resident property owners by first class mail of proposed
of Property Owners land use or zoning changes within 1,500 feet of their property, and that
such notification include information on the appeal process.
Ms. Brandal said that non-resident property owners could provide the
City with valuable information on site use, environmental, geological,
demographic, financial, and aesthetic considerations, and are vitally
concerned about the impact that legislation will have on their property
rights. She also expressed concern that the proposed Comprehensive Plan
and Growth Management restrictions will have a negative effect on
property value.
Citizen Comment Gregg Fawcett, 5408 324th Street, Fall City, owner of property in
Fawcett - Wetlands Renton, urged caution in defining specific wetland sites since property
Ordinance owners may have the right to be compensated for the decrease in property
value which could result from the designation.
