Section 7-09.3(15)A is supplemented and revised as follows:
On long radius curves (500 feet or more), either horizontal or vertical, pipe may be installed with
standard pipe by deflecting the joints. If the pipe is shown curved on the Drawings and no special
fittings are shown, the Contractor can assume that the curves can be made by deflecting the joints
with standard lengths of pipe. If shorter lengths are required, the Drawings will indicate maximum
lengths that can be used. The amount of deflection at each pipe joint when pipe is installed on a
horizontal or vertical curve shall not exceed 50 % of the manufacturer's printed recommended
deflections. The Contractor shall submit to the Engineer the pipe manufacturer's joint deflection
recommendations prior to pipe installation indicating deflections are within allowable AWWA
specification tolerances.
Where field conditions require deflection or curves not anticipated on the Drawings, the Engineer
will determine the methods to be used.
When rubber gasketed pipe is installed on a curve, the pipe shall be jointed in a straight alignment
and then deflected to the curved alignment. Trenches shall be made wider on curves for this
purpose.
Where pipe installation on curves requires the use of special fittings, concrete blocking shall be
used per Section 7-09.3(21).
Where restrained joint pipe is installed on a curve, the Contractor shall submit the pipe
manufacturer's recommendations to the Engineer for approval.
7-09.3(15)B Polyvinyl Chloride (PVC) Pipe (4 inches and Over)
Section 7-09.3(15)B is revised and supplemented as follows:

of all concrete blocking prior to backfilling.
7-09.3(23) Hydrostatic Pressure Test
Section 7-09.3(23) is supplemented and revised as follows:
The Contractor shall obtain a hydrant meter with an attached backflow prevention device from
the City to draw water from the City' water system to fill the water mains for testing, cleaning,
disinfection and for subsequent flushing purposes. The contract shall obtain a hydrant permit
from the City by completing a permit application and making the required security deposits.
There will be a charge for the water used for filling, testing, cleaning and disinfection of the
water mains.
Before applying the specified test pressure, air shall be expelled completely from the pipe,
valves and hydrants. If permanent air vents are not located at all high points, the contractor
shall install corporation cocks at such points so that the air can be expelled as the line is filled
with water. After all the air has been expelled, the corporation cocks shall be closed and the test
pressure applied. At the conclusion of the pressure test, the corporation cocks shall be
removed and plugged.
The Contractor, prior to notifying the Engineer to witness and record the pressure test, shall
have set up beforehand and successfully performed the pressure test to make certain that the
pipe is in acceptable condition. The Contractor shall then notify the Engineer at least 2 Working
Days before recording and conducting the test. The Contractor shall furnish and install
temporary blocking as required for pressure testing. Upon successful testing, temporary
blocking shall be removed.
The water main including related appurtenances and service connections to the meter setters
shall be tested in sections of convenient length under a hydrostatic pressure equal to 150 psi in
excess of that under which they will operate or in no case shall the test pressure be less than
225 psi at the highest point.
Acceptability of the hydrostatic test will be determined by two factors, as follows:
1. The loss in pressure shall not exceed 5 psi during the 2 hour test period.
UTB 1219 Exhibit A Special Provisions Page 4 of 14
2. The quantity of water lost from the main shall not exceed the number of gallons per
hour as listed in the following table.
The quantity of water required to restore the pressure shall be accurately determined by either
1) pumping from an open container of suitable size such that accurate volume measurements
can be made by the Owner or, 2) by pumping through a positive displacement water meter with
a sweep unit hand registering 1 gallon per revolution. The meter shall be approved by the
Engineer.

These standards set forth minimum standards for the planning, design and construction of water
mains and related appurtenances. These standards do not include the design of special
facilities, such as pump stations or reservoirs. These special facilities require unique design
requirements and will subject to individual review by the Water Utility.
Compliance with these standards does not relieve the designer of the responsibility to apply
conservative and sound professional judgment. The Water Utility may at its sole discretion due
to special conditions and/or environmental constraints, require more stringent requirements that
would normally be required.
The construction of all City water system improvements shall comply with the City Development
regulations and standards, the latest City adopted version of Washington State Department of
Transportation (WSDOT) Standard Specifications for Road, Bridge, and Municipal Construction
as amended by APWA and by the City of Renton Public Works Department.
GENERAL REQUIREMENTS FOR EXTENSION OF WATER MAINS
Fireflow requirements
The fireflow requirements for a proposed development, redevelopment, tenant improvements, or
for other types of building improvements or change of building usage shall be determined by the
City of Renton Fire Marshal.
A. The City Water Utility will determine the available fireflow using its computer simulated
hydraulic model of the City water system.
B. The minimum system pressure during fireflow analysis is 20 psi at the fire location and
30 psi throughout the rest of the distribution system.
New developments or redevelopment of existing sites are required to meet the minimum City
fireflow requirements. The developer shall provide information to the City to determine the
fireflow requirements for the development or redevelopment. The developer is responsible for
the design and installation of all necessary water main improvements to provide the required
fireflow including off-site and on-site water mains. The change of use of existing buildings or
areas may also require the installation of the water main improvements.
Water main Sizing
The diameter of transmission main(s) shall be determined by hydraulic analysis to verify that the
main(s) can deliver the required fire flow demand for a proposed development or redevelopment
project. The minimum size distribution system line shall not be less than eight inches (8") in
diameter and for a looped system and for a future looped system.
The minimum size distribution system in single family residential areas shall not be less than
eight inches (8") in pipe diameter when the main is serving hydrants and domestic water
services. Exception to the minimum diameter might be made in short cul-de-sacs and in areas
where looping of a water main is not feasible and when no future extension will be required. In
these cases the main stubs could be a minimum of six inches (6") in diameter if no fire hydrants
are connected. The sizing of dead-end water main without fire hydrants shall provide sufficient
flow to the domestic meters and water services.
Water mains in multi -family residential and in non-residential areas shall be sized to provide the
required fire flow demand and shall not be less than eight inches (8") in pipe diameter.
Water main Oversizing
If it is determined that it would be to the best interests of the City and the general locality to be
benefited thereby to install a larger size main than one then needed or considered by the
owners or developers immediately abutting the street, alley or easement in which such a main is
to be placed, then the City may at its own discretion, require the installation of such a larger
main in which case the City shall pay the difference in cost between the installation cost of the
similar main and of the larger main.
Any party required to oversize the water mains may request the City Water Utility participate in
the cost of the project.
Pipeline Velocities
In accordance with the Department of Health (DOH) recommendations, the City of Renton
requires that the design of new distribution mains provide for operating velocities less than or
equal to eight feet per second (8 ft/sec) under fire flow conditions and other emergency demand
conditions, and under peak hour demand.
Water Main Extension and Location
All water main extensions within the City of Renton will be extended in a manner in and along
routes which comply with the City's comprehensive water system plan.
All water main extensions shall extend through and across the full frontage of the properties to
be served and shall also be extended through and to the extreme boundaries of the properties
being developed or redeveloped. Whenever possible, provisions shall be made for looping all
existing and new dead-end mains associated with the proposed development or redevelopment
projects. An easement with minimum width of 15 feet shall be provided to the adjacent property
line or right-of-way for looping of a temporary dead-end main.
Preferred location for new water mains in City streets, absent conflict with other existing utilities,
is as follows:
(a) Water mains to be located on the north or east side of the street
(b) Water mains with diameter of 10 inches or less to be located within the paved area of a
roadway and 4 feet from the face of the curb line.
(c) Water mains with diameter of 12 inches or larger to be located within the paved area of
roadway and 6 feet from the face of curb line.
UTB 1219 Exhibit A Attachment 1 Design & Construction Standards Page 2 of 9
(d) Fittings (horizontal bends and blocking) shall be used when necessary to maintain the
uniform offset from the face of the curb line. Pipe deflection may be used on long radius
curve (radius of 500 feet) and shall not exceed one-half of the pipe manufacturer's
recommended maximum joint deflection.
(e) Water mains shall be installed with no less than three (3) feet cover from finish grade for
pipe with diameter of 10 inches or less and with no less than four (4) feet of cover for
pipe with diameter 12 inches or larger. Water mains shall have no more than six (6) feet
of cover from finish grade.
(f) When water mains are constructed on private properties and within paved areas, the
water mains shall be located outside of the parking stalls when possible.
(g) Easements are required for all water mains to be located on private properties and shall
have a minimum width of fifteen (15) feet.
(h) Water mains shall be encased in a steel casing when crossing under improvements
where the ability to remove and replace the pipe without disturbance to the improvement
is needed. Casings are required when water mains crossings occur under rockeries
over 4 feet high, under retaining wall footings, under reinforced earth retaining walls, and
under railroad tracks. Casings shall extend a minimum of 5 feet past each edge of the
improvements, or a distance equal to the depth of pipe whichever is greater. The carrier
pipe shall be supported by casing spacers, where casing length exceeds 10 feet. The
minimum clearance between the bottom of the rockery and top of pipe casing shall be 2
feet. The trench for the casing pipe shall be backfilled with crushed rocks.
