INTRODUCTION
t
The purpose of this Preliminary Design Report is to document the planning
and logistic considerations, building alternatives, costs and schedule for
redeveloping Well Nos. 1, 2, and 3 in the City of Renton. The City
currently owns and operates these three wells in the Liberty Park area
' which is located west of Interstate 40d and north of the Cedar River. Well
Nos. 1 : 2 are located to a single building in the southern area of the
park, : r ween the Cedar River, and the City's municipal swimming pool . Well
No. 3 is located in the northeast corner of the park at the intersection of
Houser Way and the Maple Valley Highway. Existing Well Nos. I and 2 will
be abandoned, while No. 3 will be used only on an emergency basis and these
' Wells will be replaced by three new wells in a single building, adjacent to
the building that currently contains Well Nos. 1 and 2.
This report contains the necessary detail to evaluate the well
' redevelopment projr--t and is organized as follows:

well Nos. 1 and 2 (located in a single building) were constructed in the
later 1140's. The wells were drilled and cased to a depth of approximately
100 feet and the casings perforated in the water bearing strata area with
a mill's knife. well No. 1 produces approximately 2,00u gallons per minute
and well No. 2 produces approximately 1.000 gallons per minute. Roth wells
' have operated relatively trouble-free, -nd in 1984 the City examined the
station in detail to dcteimine the general condition of the equipment and
the improvements to be made (if necessary) to produce an additional an
years of reliable service. The following conclusions were reached:
1. The pumps and motors are near the end of their reliable service
life and must be replaced. (In fact, well No. 2 failed in August,
' 1985, and was replaced with an interim unit).
2. The existing well casings show signs of significant corrosion and
' probably would not withstand an attempt to redevelop the wells.
This corrosion is increasing the iron content of the water supply
and will likely increase in the future.
' 3. The mill's knife perforations in the well casing have corroded and
are now holes of 2 to 3 inches in diameter, inrreasing the
probability of a well strata collapse and subsequent failure.
4. The existing well building is deteriorating and is in need of
replacement. Rehabilitation of the existing structure is not
' ecnnomically justifiable.
5. The power supply and pump control equipment is a safety hazard and
does not meet State and local codes.
2
Well No. 3 was constructed in 1962, and was drilled and cased to a depth of
t approximately 100 feet. The well is located in a buried vault, and access
to the station and operation of the equipment is both difficult and
hazardous since power supply and switch gear is in an area where standing
' water collects. The City begat+ plans in 1983 to rehabilitate this
structure and raise the operating components above grade. During eview if
the design drawings, the Department of Social and Health Services stopped
the rehabilitation project because the well is located too close to a
' nearby gasoline service station and was considered a contamination risk for
operation on a sustained basis. The DSHS did state, however, that the
rehabilitation project can be resumed if the well is moved away from the
' service station, possibly to the are,. adjacent to Well Nos. 1 and 2.
As a result of the above events, it is recommended tnat three new wells be
' constructed to the east of existing Well Nos. 1 and 2. The scope of this
Predesign Report includes some final design criteria, figures and
calculations which are presented to illustrate an example of that which can
be expected from a final design effort. Selection by the City of the
' preferred alternative will allow continuation of the design effort and the
development of detailed plans and specifications necessary for construction
of the selected alternative. It is emphasized that the primary objective
t of redeveloping these wells is to minimize the risk of water supply
contamination and/or failure.

CHAPTER 1
EMERGENCY SUP1 T AND SUPPLY CO1R[MlAT ION
' Well Nos. 1, 2, and 3, which produce a combined total of 6.600 gallons per
minute of potable water are the City's most important supply sources.
During the summer months, the City must be able to operate Well Nos. 1, 2,
and 3 to meet water system demands. One of the requirements of this
' construction project is, therefore, that the water supply normally
available from these wells be replaced by or supplemented with supply from
other sources if the well is out of service or the well must be kept in
' service and operational during the construction period. This chapter will
examine the procedures and options for supplying up to 6,600 GPM of water
to the distribution system during the construction of the new wells.
' EMERGENCY SUPPLY OPTIONS
Three options exist for supplying water to the distribution system during
the construction of these improvements.
' 1. Existing wells to remain in service and operational during
construction.
2. Abandon existing wells during construction and provide additional
supply through int,rties or other facilities.
3. Abandon existing wells during construction and do not provide
' additional supply,
Option No. 1, to keep existing wells in service during construction is the
' preferred alternative. This option has the disadvantage of being the most
costly of the three presented, and it is Passible that operation of the
well during or after drilling may produce water with high turbidity. The
impacts of this may be minimized, however, if the new well drilling is
completed in the winter when the existing wells can be shut down.
Restarting the wells after the drilling is complete should produce only
several minutes of tur: :d cater and this can be discharged into the river
' or sands and silts can be settled in the Mt. Olivet Reservoir. This option
has a distinct advantage in that the supply for the summer of 1986 is not
dependent on neighboring districts. this option also does not preclude the
use of interties if they are required for an emergency.
' 4
i
1
i 9ption No. ? to remove the existing wells from service and provide
intertie supply for the summer of 1986. is not a preferred alternative.
Although there is sufficient intertie capacity to match the supply from
1 Well Nos. 1, 2, and 3, the intertie supply is not automatically operated.
It must be manually activated and constantly monitored since some of the
adjacent syscros do not operate at hydraulic elevations (pressures) that
are normally compatible with the City's. This option would also a, .e the
i City dependent on thr reliability end supply capacity of neighboring
districts for it water supply.
' Option No. 3 is unacceptable since it does not provide sufficient supply to
meet system demands.
iINTERTIES FOR EMERGE':--Y SUPPLY
Even though it is the recommendation of this Report that the existing wells
i remain in service, it is possible that the wells could be tenporarily or
permanently damaged durioq construction of the new wells. The following
interties may be used for emergency supply during this type of situation:
1. Seattle supply through Tiffany Park Pump Station to Rolling Hills
590 Zone, Supply Rate - 1,050 gpm,
2. Seattle supply through Fred Nelson Pump Statfcn to Rolling Hills
590 Zone, Supply Rate - 450 gpm.
' 3. Kent supply at Valley General Hospital to Downtown 196 Zone, Supply
Rate - 2.400 gpm,
' 4. Seattle supply through Nest Hill Pump Station pressure relief valve
to Downtown 196 Zone, Supply Rate • 2,600 gpm.
S. District 90 supply though intertie at SE 128th and Union Avenue,
Supply Rate • 2,200 gpm.
Total potertial Intertie Supply Rate - 8.700 gpm

CHAPTER 2
' WELL LOCATION
' Following the decision that was made in 1983 to relocate and rehabilitate
the existing wells, a site immediately adjacent to the wells was noted as a
Potential location. Efforts since that time have proven that this location
(approximately 40' east) is the best alternativ-. Efforts to identify a
'better" location have been unsuccessful considering the constraints o• the
final location, and we recommend that the new wells be located adjacent to
' existing Well Nos. 1 and 2. (See Figures 3 and 4 for details). This
location has the following advantages:
1. Adjacent to site of existing water rights. Therefore, there is no
requirement to aply for new riq is in the restricted Cedar River
Basin.
' 2. Area of known high aquifer yields.
3. Level construction site.
' 4. Site owned by the City.
S. Few interfering utilities.
6. Adjacent to distribution system connedion.
T. Pnol chlorination equipment may be relocated to new facility to
' meet code and safety requirements.
' SITE CONSTRAINTS
It is intended that the following constraint will be considered during the
final design effort at the proposed construction location:
1. The existirg maple tree in the southeast corner of the construction
site is to be saved, if possible.
2. Well drilling procedures must not adversely impact the swimming
pool.
' 6
3. Relocate the following utilities: telephone, pool power
transformer, sprinkler piping, abandoned pool side sewer.
' 4. Maintain foot access to pool pipe gallery duriro the construction
operations since access to this facility is required on a regular
basis.
' 5. Oo not damage existing well facilities.
6. New well ca.:ings must be at least 12 feet apart.
' 7. Use existing driveway for construction access to minimize
construction damage and disruption of park activities.

CHAPTER 3
' DRILLING III.TE UTI11ES
Recause the proposed site is a City Park, it is very sensitive to
unnecessary damage and encumbrance. Also, because of the importance of
' maintaining operation of the existing wells, drilling procedures must be
carefully monitored and controlled. Three drilling options are available
at this site:
' 1, Rotary Drilling
2. Reverse Rotary Drilling
3. Cable Tool Drilling
DRILLING OPTIONS
' Rotary drilling and reverse rotary drilling are both accomplished by
producing a slurry in the cared ho +nd "floating" the spoils out of the
casing by injecting water into ei wer the interior or exterior of the
dri 'ing column and collecting the mud in a pit for settling. Both of
then, drilling options can produce a large diameter hole for the least
cost, and both have a very low probability of impacting the pool. In
addition, the reverse rotary drilling method offers the lowest probability
of producing high turbidity in the aquifer. Both of these options are
unacceptable, however, because of the large amount of Park area required
' for settling mud and the quantity of water required for the drilling fluid.
' The cable tool drilling method, although offering a slightly higher
probability for aquifer turbidity and surrounding structure damage, is the
preferred drilling option. This method requires very little area for
construction and no water supply for drilling. We recommend that the
' existing wells and the pool he carefully monitored during drilling for
structural damage and that the wells be pumped to the sanitary sewer to
clear the aquifer at the end of each drilling day, during the first well
' construction. This first well can then be pumped during construction of
the remaining two wells to prevent fine material in the aquifer from
migrating to the existing wells and reducing their yield. Since the
adjacent swimming pool is of the double-wall type, and the water retaining
t8
walls are not in contact with the surrounding soil , the probability of
' damaging this facility is very low. :f necessary, an independent
structural examination and/or leakage test can be conducted prior to and
after well drilling.
HYDROGEDLOGIC CONSIDERATIONS
' Well Nos. 1 and 2 currently produce 5.000 gpm with less than 4 feet of
drawdown in the aquifer. Because of this observed high aquifer
transmissivity, we anticipate a high probability of obtaining 6,600 gpm
from the new well facility. The following consideratiuns, Ivowocer. Oill
minimize the potential for lower production rates. All of the wells should
be drilled to -Pe bottom of the aquifer to minimize the drawdown effects
that the wells will have on one another. We anticipate that this depth
will be approximately 100 feet, the same as the existing wells. Minimum
well spacing should be 12 feet to minimize well turbulence from influencing
1 adjacent wells. The wells should be equipped with 24" diameter casings,
the largest normally available to minimize screen velocities, sanding
problems, and interference between the pump and casing.
During a television inspection of the existing w. ' iS in 1984, the material
visible behind the .Rill's knife perforations in .ne casing appeared to be
large rocks, 3 to 6 inches in diameter. We, therefore, recommend the use
t of a reinforced drive shoe during well construction with a cutting edoe to
penetrate this potential rock area.
' Because of the high yield necessary from these wells, each well should be
pump tested as it is completed to calculate the interference effects of
locating the wells with this spacing, and to examine potential well yields
1 and problems before the pumps are specified and ordered.
1 CHAPM 4
' WELL FIELD PROTECTION
' Because of the transmissivity of the geologic strata in the existing %ell
field and the high ground water level (20 feet below grade), the City is
acutely concerned with well field protection. This chapter identifies the
efforts to be taken to minimize the probability of adverse impacts on the
aquifer at the existing wells and at the proposed wells. Recaase of the
importance of the aquifer in this area to the City's water supply, these
procedures should be strictly enforced.
' EXISTING FACILIIIES
The following precautions will minimize the potential for contaminating the
texisting wells during construction!
1. Do not allow vehicles carrying hazardous materials onto the
' construction site.
2. Limit the use of petroleum products and product storage during
construction to that absolutely required. Store all products on
' leak-proof membranes with retaining curbs.
3. Do not allow constriction or other equipment on the site that leaks
fuel or hydraulic fluid.
4. Remove the abandoned pool side sewer.
5. Abandon existing Well Nos. 1 and 2 per AWWA guidelines and DSHS
directions if removal of the casings is unsuccessful. The wells
should be backfilled with clean gravel to the static water level,
' then with bentonite clay to the surface. The top of the casing
should be permanently capped.
The City may choose to monitor water quality at the existing wells on a
weekly basis during new well construction to identify and resolve quality
oronlems as soon as possible.

1 PROPOSED FACILITIES
The following precautions will minimize the potential for contamination of
ithe new wells during their normal service life.
1. Locate the new well pumps and itors on independent. cast-in-place
1 concrete curbs to prevent surface water from entering the casing.
The top of the curb and the pump control valve elevation should
both be above the high water level point if the building is
flooded.
i2. Use a grout or clay surface seal for all wells.
1 3. Leave casings at least 24' above finished grade with a solid welded
top after well drilling.
4. Place a solid, vandal-proof top on the exposed casing at the end of
ieach drilling day.
5. nisinfect all drilling equipment and the casing as required to
prevent contaminants from other drilling sites from entering the
I, aquifer, through .he drilling equipment.

CHAPTER 5
BUILOINC ARCNITECTURE
' This Predesign Report presents two distinct and separate architectural
alternatives for the new well building. Because of the sensitivity of the
project site (City Park, high traffic area, high visibility, adjacent to
River) the success of this project will be determined to a large extent by
the appearance of the completed facility.
Each of the alternatives has been selected because of its desirable
combination of operation And maintenance characteristic for the Water
' Utility and continuity of style with other Park facilities for the Park
Department. The styles are listed herein as: "Option A" - a modified
rectangular building that follows the style of the baseball stadium in
Liberty Park, and "Option B" - a hexagonal building that follows the style
' of the gazebo in Liberty Park and all of the buildings in Coulon Park.
Details of each building can be found 'n Figures 3 through 9, and Chapter
10 contains cost estimates for each facility.
1 We have investigated each style in sufficient detail to determine if the
building is feasible and practical and to prepare a detailed cost estimate.
It is the City's choice to determine which option is to be used for the
' final design effort. Although this Report states no preferred
architectural style, we suggest all appropriate City departments be
involved to the degree needed in the selection.
' During the development of each building type, the following constraints
sere applied to each option:
' 1. Each building must contain three wells in a single room at a
minimum spacing of 12 feet on center,
' 2. Provide a removable skylight/access hatch over each pump for minor
pump removal and maintenance. Provide a double opening door
opposite each pump so that a crane operator can see the pump and
motor during maintenance work.
3. Provide a removable roof and wall section over each pump to permit
a drilling rig to back over the well casing for major repairs or
' well development work.
' 12
1
1
a, Provide a minimum of 5 unobstructed, straight-run pipe diameters
1 upstream of the flow meter.
5. Provide 5 separate rooms in addition to the pump room for the
1 following:
1. Pool chlorine storage
2. Pool chlorine injection
1 3. Well chlorine storage
a. Weil chlorine injection
S. Well fluoridation
1 6. Al' flocr drains are to be connected to the sanitary sewer due to
the possibility of chlorine or sodium fluoride contamination.
1 7. Eaty access to chlorine and fluoride rooms for chemical delivery.
B. Use of low maintenance, non-combustible materials for construction.

BUILDING FEATURES, OPTION A - RECTANGLE
1 The modified rectangle (Figures 5 and 6) follows the stadium architectural
style in Liberty Park with smooth, concrete columns and exposed aggregate
walls. The builuing features a pre-formed corrugated metal roof deck and
1 relites for natural lighting in the building's interior. In this
configuration, the wells would b> placed parallel to the River, and the
interior piping plan would be symmetrical with 10 unobstructed,
1 straight-run pipe diameters upstream of the flow meters for improved
accuracy. The configuration is the least expensive alternative.
1 BUILDING FEATURES, OPTION B - NE%A.GON
The hexagonal shape (Figure 7) matches the buildings in Coulon Park and the
1 gazebo in Liberty Park, This compact shape uses the least amount of park
area while maintaining easy access to the pumps and motors. The removable
roof sections in this design contain no sealing surfaces perpendi G-lar to
1 the stormwater flow line for improved wee her protection. This building
would be constructed with a brick exterior and pre-formed corrugated metal
root decking.

' CHAPTER 6
' UTILITIES
lnis chapter will identify interfering utilities in the construction area, !
and provide recommendations for relocation and/or connection. Refer to
Figure No. 2 for details.
RELOCATED UTILITIES
During the summer of 1985, a contract :vas executed to construct a portion
' of the City's 24" transmision pipeline tram Well Nos. 1 and 2 to the Wells
Street Bridge. Prior to this work, them, were interfering utilities in the
proposed construction area of the new well. The City had the transmission
pipeline contractor perform most if the utility relocation in the planned
' construction area. This relocation included three water mains and a
sanitary sewer pipeline. City-owned telemetry conduit was also relocated
out of the construction area during the winter of 1984-1985 by a contractor
' doing other work in the City. These utilities are now reloc ted and
operational,
INTERFERING UTILITIES
Some utilities have not been relocate' at the planned construction site for
' the new wells lhey include:
1. Tel•�,iione service to pool. This service is currently being used by
' both the bath house for voice service and by the Water Department
for telemetry it the well . The new well facilities till not
require telephone service and, therefore, the Park Department
should request a new service when the old well is abandoned.
2. Gas service to pool. The existing service runs parallel to the
south wall of the bath house and will probably not be affected by
the new construction operations. Care should be Laren in notifying
the well construction contractor of this service.
' 3. Sprinkler system piping. Sprinkler system as-built records may not
be accurate and, therefore, no attempt has been made to relocate
this utility. We suggest that the contractor be allowed to remove
' 14
al piping he encounters or damages during construction and to
' install new piping to fit the final landscaping layout.
4. Side sewer pipeline, Although the replaced section of s le sewer
pipeline for the bath house has been abandoned, we suggest that
this be excavated and removed. This will eliminate the possibility
of trapped waste in the pipeline leaching into and contaminating
the aquifer if this pipe breaks during the construction operations.
UTILITY CONNECTIONS
The well pump discharge piping should be connected to the 240 ductile iron
pipeline at the tee provided as shown on Figure No. 2. This tee stubout
was constructed earlier in 1985 and was placed specifically for connection
to the new well building.
It is anticipated that a new pump bypass pipeline will need to be
constructed froh, the well building to the River since the condition of the
existing pipeline is unknown and, therefore, its remaining life is
unpredictable. Since it would be significantly less expensive to locate
and use this pipeline, if possible, than to construct a new pipe to the
River, this existing line should be exposed during construction of the new
well building and a determination of condition made at that time. All
floor drains should be connected to the sanitary sewer due to the
possibility of fluoride, chlorine, lubricating oil or other chemicals
entering the floor drains. Chapter 7 addresses power supply connection and
requirements while telephone and gas service will not be required at the
site.

1 POWER SUPPLY ALTERMTIVES
1 This chapter discusses options and provide re.ommendations for pourer supply
tc the new well facility.
MOTOR STARTING OPTIONS
1 Four possible motor starting options have been identffied:
1 I. Start all motors "across the line
2. Use reduced voltage starters for all motors.
L Use reduced voltage starters for some motors.
4. Use an engine generator set for load shedding (motor starting).
1 Option No. 1, "across the line" starting is the preferred motor starting
alternative since it uses the least expensive and least complicated
' electrical motor starting equipment. In some cases, however, the power
utility cannot accommodate the large in-rush current associated with
starting large motors across the line. Although Puget Sound Power and
Light Company has indicated that they can start three ISO horsepower motors
1 across the line if they are not started simultaneously, this arrangement
would require a substantially larger standby power generator than motors
using reduced voltage starting. Standby power supply to this and the other
1 well facilities ;s recommended by the City's Comprehensive Water System
Plan; 80, therefore, the ability to start these wells from a generator is
a prime consideration.
1 Starting loads can be reduced by either specifying a motor with a "better"
NENA code rating or by reduced using options 2 or 3. It is advantageous to
the City to ootain an improved NENA code rating because reduced voltage
starter . shorten motor life and reliability, and improved motor NENA code
ratings generally result in a higher quality, longer life motor. The
better NEMA code motors are slightly more expensive to operate because of
1 an increase in rotating mass (higher electrical power consumption during
running); however, the tradeoff in reliability and ease of starting is
justified.
1
1 16
' Optior. No, a would require that a >tandby engine generator be used to
reduce utility loads during motor starting. Since Puget Power can
accommodate starting the %rotors without load shedding assistance, this
option is an unnecessary expense and complication. It should be
' remembered, however, that future utility rate structures may make this
alternative feasible or even mandatory, and power supply equipment design
must consider this eventual possibility.
We recommend that t%- new facility be designed for 'across the line'
starting, using meta, +ith a 'NENA Design R' code rating for minimized
starting loads. This arrangement will minimize future engine-generator
' sizes. Control circuits should be provided with logic to prevent
simultaneous pump starts under any conditions.
TRANSFORNER OPTIONS
Three options exist for locating and sizing power supply transformers for
the new facility.
1. Use existing transformers (do not relocate)
2. Use existing transformers (relocate)
3. Use new transformers
Puget Sound Power and Light has examined the existing transformers at the
well site and have indicated they would not recommend reuse of this
equipment. Replacement transformers are too large to be buried and must be
located above grade on pads; therefore, we have located the transformers
away from the new building to minimize visual impact. Recommended
transformer locations are shown on Figure Nos. 3 and a. Power supply to
the well and pool should be encased in buried, galvanized steel conduit to
maximize reliability and minimize potential digging hazards.

rAUTOMATIC CONTROL
rThis chapter discusses the automatic control requirements of the new
r facility. The new well facility should be operated as three separate
remote sites (Well Nos. 1. 2. and 3) to allow individual flow rate
monitoring and recording of each well at the master console. This
procedure will require that the existing remote telemetry unit (RTU) at
Well Nos. 1 and 2 and the unit at Well No. 3 be reused and an additional
RTU be purchased for the third well. A new master pump unit and digital
switch set will also be required at the master console for the third well
r operation.
The new wells should have the following control features:
' 1. Normal (automatic) start/stop fang Talbot Hill Reservcir level by

2. Low aquifer level shutdown (each pump) - locally controlled.
r 3. Low discharge pressure shutdown (each pump) - locally controlled.
4. High discharge pressure shutdown (each pump) - locally controlled.

ALARMS
rThe telemetry link with the master console should use the existing
City-owned hardware. Alarm sequences should use the format currently in
use by the automatic control system.
rThe following conditions should be alarmed at the master console:
r 1. Pump fail (each pump).
2. High/low discharge pressure (each pump).
3. Low aquifer level (each pump).
r 4. Intrusion.
5. Power fail.
6. Low battery backup on control system.

7. Telemetry link.
' R. Data fail .
9. Fire alarm (any roam).
10. Chlorine gas leak (any room).
11. Low Fluoride concentration.
12. Low Chlorine residual.
' RECORDING (RECOROKEEPING)
Since historical operation is the best measure of a facilities current
' condition and performance. the following conditions should be automatically
recorded by the Telemetry and Supervisory Control System:
' 1. Flow rate at each well (master console).
2. Well level (Nell No. 9 telemetry room).
3. Total flow each well (motor control center).
a. Number of pump starts (motor control center).
5. Running time of pumps (motor control center).
6. Fluoride lnjectior concentration (fluoride room).

' CHAPTER 10
MECHANICAL
1
' This chapter examines and detailsthe mechanical equipment required for the
new well facility, including pumps and motors, piping and valves, flow
meters, ventilation, and chlorination. and fluoridation chemical delivery
' systems.
PUMPS AND VOTORS
It is recommended that new pumps and motors be used since the existing
wells are to remain in operation during construction. Further, the
existing equipment is reaching its reliable service life and the capacity
should be divided equally which is not possible with the existing pumps and
motors. Each of the three pumps should have a design pumping rate of 2,200
' GPM at 220 feet TDH for a total supily rate of 6,600 GPM. This capacity
will match the existing total water right quantities.
' PIPING
Although the three wells are being located in a single roan, for reasons of
' accurate recordkeeping and system reliability each well pump and motor are
to be controlled and maintained as an independent well . In this manner,
the performance and efficiency of each pump can be closely and individually
' monitored. In the event of a malfunction of a flow meter or pump control
valve, this would ensure that the repair could be accomplished without
affecting the operation of the other two wells. In view of the above, the
following recommendations are made:
1. Use a pump control valve on each pump and pipe the startup flow to
the river.
2. Utilize a check valve with opening and closing speed controls on
each pump.
3. Use a 12-inch flow meter on each pump before the discharge piping
is manifolded together,
' 4. Use an isolation valve on the system side of each flow meter.
' 22
5. Locate valves and meters in easy-tc-service locations.
1
FLOP METERS
' The piping plan should be designed to accommodate five pipe diameters of
straight unobstructed piping upstream of each flow meter. This is a
standard recommended minimum to ensure accurate meter recording, and is
1 possible with either architectural alternative. Each meter is to be 12
Inches in diameter and have a flow range of at least 0-2,500 GPM with a
0-20 pulse per second (PPS) output for the avtemetir control system. Each
' flow meter should S� a propeller type meter, since this design has the
advantage of high reliability at tow cost. The flow meters are to be
interfaced with a local and remote flow rate indicator and flow totalizer
for monitoring of each pump, permitting a rapid recognition of pump
problems should they arise.
VENTILATION
Pror^- ventilation design is an important consideration when dealing with
potentially harmful gases. Each room including the chlorine storage rooms,
shall have separate torced air ventilation to ensure that gases are not
mixed from room to room and that equipment leaks will be contained to the
' room in which they originate.
The fans shall be sized so as to fully exchange the air in each roan once
every five minutes. From their location on the ceiling or high on the
' wall , the ventilators should blow fresh air into the room, with the exhaust
leaving the room through louvers near the bottom of the doors. The
relative location of all the ventilation equipment shall be si-ch that there
' is maximum air circulation throughout each room, thereby minimizing any
areas of stagnant air.
' CHLORINATION
Both building alternatives include two chlorine rooms in their design, one
' for potable water and the second for the swimming pool. Each facility is
to be built and maintained separately. However, the same type of chlorine
equipment can be used for both the pool and potable water systems. Each
' well is to have its own chlorinator and a separate injector downstream of
the flow meter but before the header. The pool chlorinator shall have
manual pacing controls. For safety reasons, the chlorine tanks should be
stored in a separate room from the chlorinators. The cylinder storage
' roans are to have their o" heat controls as well as ventilation,
' FLUORIDATION
The proposed facilities include a roan to be used for the well fluoridation
equipment. The fluoride roam should he equipped with an emergency shower
' in case of sodium fluoride dos'. contamination. The room should be large
enough to accommodate the fluoride equipment while providing an ample
23
working area, as well as a Storage area for one week's supply of sodium
fluoride. It is ,recommended that a pacing system not be used due to its
complexity, and the possibility of over fluoridating the water. The
following recommendations are made concerning the fluoridation equipment
tftsel f:
1. Use a bag feeder with dust control for sodium fluoride crystal
transfer.
2. Size the saturator for the addition of one bag of sodbmn fluoride
Der day at maximum well capacity.
t7, The day tanks shall be sized for continuous solution makeup.
4. Provide two day tanks with the ability to use either one.
5. Provide a separate Injection pump for each well with one spare
' pump which is manifolded to pump to any well.
6. Use a water softener for the makeup water to reduce injector
clogging from magnesium and calcium precipitates.
' 1. Use a dehumidifier in the fluoride room to help prevent the sodium
fluoride from caking and, therefore, cut down on material waste
' and equipment cleaning.

pproximately 4% to reflect a 4th quarter of 1986 bidding condition. Since
this project will relocate the withdrawal point of Well No. 3, and is being
accomplished for water quality as well as other reasons. the Department of
Social and Health Services has indicated that this project will be
considered for a 40% State grant. This funding should be pursued and the
grant application submitted as soon as this 'eFort is approved.

' CHAPTER 12
EXISTING FACILITY DEMOLITION AND PARK RECLAMATION
' This chapter discusses the demolition of the existing wells I and 2
facility, the procedures for salvaging existing equipment and
recommendations for the reclamation or the Park area.
' DEMOLITION
As discussed in the introduction to this Report, the existing Well Nos. I
' and 2 facility is to be abandoned and demolished at the completion of the
new well construction. The proc Mures for maintaining operation of the
wells during construction have been outlined in other chapters of the
Report. The purpose of the demolition effort will be to remove all parts
of the existing Wells I and 2 facility that will interfere with returning
the Park to a condition equal to or better than that prior to the
construction of the well and includes removing the well building to below
finish grade, removing the chlorination building, removing the power supply
transformers, and removing the paved asphalt parking area.
' It is recommended that an attempt be made to remove the existing casings
since this will minimize the possibility of iron bacteria contamination in
the aquifer. We have reason to suspect, however, that the casings are too
weak to be removed, and that this effort will be unsuccessful, if the
' casings cannot be removed, they should be abandoned by backfilling the
holes with clean gravel to the static water level, and then filling to
grade with bentonite clay. After the casings are filled, they should be
' covered by a welded steel cap.
It is suggested that the floor of the pump station be perforated or
broken to permit surface water drainage through the structure after it is
covered. We do not recommend removing all of the old building foundation
since the excavation necessary to do th-ls might impact the swimming pool
and the new well building.
The demolition and reclamation contract should be separate from the well
construction contract, since many contractors specialize in this type of
work and this allows the City close control over the scheduling of the
' contractors. The demolition Cont.ract documents shwld require providing
pedestrian access to the swimming pool at all times.
' 27
' SALVAGE
Several items in the existing well facility are in good operating condition
and should be salvaged and kept as spare equipment. with the exception of
the fluoridation equipment and the telemetry equipment, it is our
recommendation that the existing equipment not be placed in the new
facility for the following reasons: 1) the existing facility must remain
wholly operational during new facility construction, and 2) used equipment
' would not be covered under the warranty period provided by the contractor.
It is recommended that the following equipment be salvaged and kept as a
' spare with the exception of 6 and 7 below which would be used in the new
facility:
1. Well Dumps and motors.
' 2. Chlorination equipment.
3. Check valves.
4. Automatically controlled valves.
5. Motor starters.
6. Fluoridation equipment.
7. Automatic control (telemetry) equipment.
' The fluoridation and telemetry equipment can be used in the new facility
sinw.e this equipment will be provided in 1986 under separate contract, and
a failure of this equipment will not reduce the capacity to supply water to
' the distribution system.
Previous discussions with the City have revised the question of rel neat;ng i
' the chlorination building intact to the West Hill Pump Station for
chlorinating the West Hill area. Our discussions with va^ious contractors
have shown that this is not economically feasih'.e, and therefore, it is
recommended that the existing chlorine building be demolished.
PARK RECLAMATION
Since it is the recommendation of this Report to demolish the existing
Wells 1 and 2 facility, that area of the Park currently occupied by this I`
building will be available for use by the Park Department. Since the
' existingstructures are opposite the municipal DD D Pool. the Park Department
maw wish to consider several options:
' 1. Return the Park to a lawn condition.
2. Provide grandstand or other seating for pool viewing. '
3. Improve access to the swimming pool pipe gallery.
4. Expand the bath house.
We suggest that the Park Department have direct input into the reclamation
contract so that the area is left in a condition that will most benefit
' their future plan•,

Subject: Comprehensive Water System Plan Amendment for the
,' Reconstruction of Well Nos. 1, 2, and 3 and for the
Fluoridation of the City's Water Supply
0ear Mr. Houghton:
The City's Comprehensive Water System Plan prepared and adopted in 1983 d'd
not contemplate the reconstruction of Well Mos. 1, 2, and 3, nor the
Implementation of fluoridation of the City's Water Supply. To ensure that
the City has maximum opportunity to secure DSMS grant funding for these
projects, it is necessary to amend the Comprehensive Water System Plan, In
accordance wltn our authorization, we have prepared the Amendment to the
Comprehensive Plan addressing these items. Attached as Exhibit 1, the
Amendment sets forth the changes in the Comprehensive Plan Engineering
Report necessary to accommodate the projects as currently proposed, and
provides background information explaining these changes. The cost of
these projects results in a substantial impact on the City's Water and
Sewer Capital Improvement Program. We have prepared an amended Water and
' Sewer Capital Improvement Program for the period ending 1990. Adjustments
In previous scheduled improvements have been made to accommodate the
changed cost of the Well Nos. 1 , 2, and 3 and the addition of the
' fluoridation project not anticipated in the original Capital Improvement
Program,
The adjustments to the Capital Improvement Program are illustrated in a
3-page tabulation attached as Exhibit 2. This Exhibit compares the original
planned expenditures to the actual amounts budgeted and spent in the years
1983-1985 and then to the budgeted or proposed budget for 1986-1990. These
proposed expenditures identified in the years 1986-1990 as budget or
estimated budget constitute the revised Capital Improvement Program
Proposal , Gt the end of Page 3 of Exhibit 2, we have compared the total
Capital Improvement Program Budget for each of the years 1986-1990 to the
funds available for capita' improvements based on the already enacted 17%
water/sewer rate increase for 1986 and a proposed water/sewer rate increase
of 12% each year for the years 1987-1990. This comparison illustrates that
adequate capital improvement funds can be provided through the enactment of
annual rate increases of approximately 12% through 1990.

Ine required rate ;ncreases have Deen evaluated using the program
Utility Plan by Microflex. Exhiu.t 3 contains the results of this
analysis. The analysis is based on realistic parameters developed from a
review of the Utility's historical operating results. Annual growth of the
Utility is projected at 1.8% where historically the growth has exceeded
this rate for the past it years. Water consumption which is used as the
basis for the rate increase requirement has been projected cased on the per
customer average of the past siy. years. Per customer water consumption
data was examined for the past it years, but higher industrial usage in the
early part of this 11-year period unreasonably skewed the average
consumption figures; and, therefore, the use of average figure; for the
past six years has resulted in a more conservative projection.
Exhibit 4 presents for the Staff an annual listing of the capital
improvements proposed for both the Water and Sewer utilities for each year
beginning in 1987 and ending with 1990.
Exhibit 5 is prepared for presentation to the Council Utility Committee and
to the full Council in support of the Comprehensive Water System Plan
Amendment. This Exhibit is a 2-page summary of the Water/Sewer Utility
Capital Improvement Program as amended for the years 1986 through 1990.
The tabulation presents the 1986 budgeted items and estimated budgets for
1987, 1998, 1989. and 1990. On Paye 2 we also compare the resulting total
capital improvement budgets for each year to the total available for
capital improvements based on proposed water rate increases in each year.
This tabulation is a reduced and condensed form of the tabulation set forth
in Exhibit 2.
We are enclosing 12 copies each of Exhibit 1 and Exhibit 5 which can be
used in presentation to the Council Utility Committee and to the full
' Council.
I trust the items, as transmitted herewith, will be sufficient to proceed
with the Comprehensive Water System Plan Amendment by the City Council. If
' we may assist further in any way during this process, please advise us.

BACKGROUND
1, Wells 1, 2 and 3
Prepared in 1983, the City's Comprehensive Water System Plan provided
for improvements to existing Wells 1, 2, and 3 to ensure that they
would continue as the City's longterm, reliable and contaminant-free
source of water supply. In 1984, the City initiated investigations of
M
Amendment No. I

Wells 1 and 2 to determine the extent of rehabilitation necessary for
assuranre of continued `o item (40 years) i-liable service from rh�se
wei'S. AS e rr,,il t or
were reached:
1. The pumps and motors are near the end of their reliable
service life and must be replaced. (In fact, Well No. 2
failed in August, 1985, and was replaced with an interim
unit).
2. The existing well casings show signs of significant
corrosion and probatly would not withstand an attempt to
redevelop the wells. This corrosion is increasing the
!run content of the water supply and will likely
increase in the future.
3. The mill's knife perforations in the well casing have
corroded apd are now holes of 2 to 3 inches in diameter,
increasing the probability of a well strata collapse and
subsequent failure.
4. The existing well building is deteriorating and is in
need of replacement. Rehabilitation of the existing
structure is not economically justifiable.
5. The power supply and pump control equipment is a safety
hazard and does not meet State and local codes.
In 1983 the City initiated the development of engineering construction
plans for improvements to Well ;io. 3. The primary objective of these
improvements focused on elimination of the below-grade vault in which the
well equipment was housed, and construction of a new pump house with
' equipment and pump located above-grade.
During a review of this -e-design, the Department of Social and Health
' Services stopped the rehabilitation program due to the proximity of the
well to a gasoline station; the well's location was considered to pose a
contamination risk to operation on a sustained basis. Improvements to
gasoline storage facilities have eliminated immediate contamination
concerns at this well . However, proximity to similar adjacent developments
and arterial streets provides future exposure to similar contamination.
The proposal to relocate Well 3 by drilling a new well adjacent to Wells 1
and 2 in conjunction with their redevelopment will increase the protection
of source of supply by removing it from a location adjacent to potential
contaminant survey. Existing Well No. 3 will be maintained as an emergency
back-up facility in the event of facility failures at Wells 1, 2 and 3.
rvnemmment No. t
Page 5
As a result of these preliminary findings, the scope-of-work of the
Pre-Design Study and Report for Wells 1 mid 2 was expanded to include Well
t ' .
Redevelopment, January, 1963 sets torin the aetailed recomnendaU ons,
cost, and time schedule for the redevelopment of Wells 1, 2, and 3. The
redevelopment will assure the City of a longterm, contaminant-flee source
of supply at this location.
The Amendment to the Water Comprehensive Plan as proposed herein is based
on the findings of this Report. Implementation of the recommended
improvements is essential to the City's continued use of this vital supply
source.
2. Fluuridation
"Fluoridation of the City's water supplies with levels recommended by the
State Department of Social and Health Services with program costs funded
through water utility rate adjustments" was supported by the voters of the
November 5, 1985 General Election. The staff report of July 31, 11184.
provided an overview of the public benefits and opposition to fluoridation,
the facilities necessary to fluoridation of the City's water supply, and
the capital and annual costs.
The professional consultant engineer retained to design the equipment ..nd
facilities necessary to fluoridation of the water supply has provided tie
following recommendations:
a, Process Chemistry - Sodium fluoride compound in a crystalline form
to be used,
h. Application Points - Application to be only those sources of
normal water suppl., and that water supply sources only used
intermittently or on an emergency basis, not to he equipped for
fluoride treatment (treatment of Wells 1, 2 A 3; Wells 8 A 9; and
Springbrook Springs).
C. Application Method and Process Equipment - Application be by
' injection of a saturated sodium fluoride solution to the water
supply by metering through r positive displacement pump.
Equipment at each locatio-i to include (1) up-flow saturation tank
with flow control , (2) day tank and transfer pump, (30 positive
displacement metering pump, and (4) auxiliary equipment.
d. Equipment Location - Equipment should be located at the new Wells
1, 2 and 3 Building; a new building adjacent to Wells 8 A 9; and
in ti,e unused roan at the Springbrook Springs chlorination
facility. Equipment at Wells 1 and 2 would temporarily be
installed in the pool filter gallery until the new 5uilding is
completed. Space for dry chemical storage can b- provided either
at the new Fluoridation Building for Wells 8 A 9 or Wells 1, 2, A
3 Building.
