1. ALL WORK AND MATERIALS SHALL BE IN ACCORDANCE WITH THE LATEST EDITION OF THE CITY OF RENTON PUBLIC WORKS
STANDARD SPECIFICATIONS AND SPECIAL PROVISIONS AND WSDOT / APWA STANDARD SPECIFICATIONS, LATEST EDITION AS
AMENDED BY THE CITY OF RENTON. A SET OF CITY APPROVED PLANS SHALL BE KEPT AT THE JOB SITE WHENEVER CONSTRUCTION
IS IN PROGRESS. A PRE -CONSTRUCTION CONFERENCE SHALL BE HELD PRIOR TO THE START OF CONSTRUCTION. THE CONTRACTOR
AND OR DEVELOPER SHALL BE RESPONSIBLE FOR SECURING ALL NECESSARY PERMITS PRIOR TO CONSTRUCTION.
2. ALL EXISTING UTILITIES SHALL REMAIN IN SERVICE DURING CONSTRUCTION UNLESS OTHERWISE NOTED. THE CONTRACTOR SHALL
CALL 1-800-424-5555 TO VERIFY UTILITY LOCATIONS BEFORE BEGINNING EXCAVATION.
3. ALL MATERIALS USED FOR THE CONSTRUCTION OF WATER SYSTEM IMPROVEMENTS SHALL BE NEW AND UNDAMAGED, AND
"CATALOG CUTS" FOR ALL MATERIALS SHALL BE APPROVED IN WRITING BY THE CITY OF RENTON PRIOR TO BRINGING ANY
MATERIALS ON-SITE.
4. ALL WATER MAIN PIPE MATERIALS SHALL BE CEMENT LINED DUCTILE IRON PIPE, THICKNESS CLASS 52 PER AWWA C 151 AND C
104. PIPE JOINTS SHALL BE PUSH -ON OR MECHANICAL JOINT. CAST IRON OR DUCTILE IRON PIPE FITTINGS SHALL BE CLASS 250 AS
PER ANSI/AWWA C110/A21.10-82. ALL DUCTILE IRON PIPE AND FITTINGS SHALL BE WRAPPED WITH 8 -MIL BLACK, TUBE -TYPE,
POLYETHYLENE PLASTIC PER AWWA C105 STANDARDS.
5. MINIMUM COVER FROM TOP OF WATER MAINS TO FINISHED GRADE SHALL BE 36 INCHES FOR PIPE DIAMETER OF 10 -INCH OR LESS
AND 48 INCHES FOR PIPE DIAMETER OF 12 -INCH AND LARGER. MAXIMUM COVER FOR ALL WATER MAINS SHALL BE 60 INCHES.
ANY DEVIATIONS MUST BE APPROVED BY THE CITY OF RENTON PRIOR TO CONSTRUCTION. WHERE UTILITY CONFLICTS OCCUR,
THE PROFILE OF THE WATER MAIN SHALL BE ADJUSTED AS NECESSARY TO CLEAR CONFLICTS AND TO PROVIDE MINIMUM COVER.
PIPE DEFLECTION SHALL NOT EXCEED ONE-HALF OF PIPE MANUFACTURER'S SPECIFICATION FOR SIZE OF PIPE USED. ALL TRENCH
BACKFILL SHALL BE COMPACTED TO 95 PERCENT MAXIMUM DRY DENSITY AS DETERMINED BY THE MODIFIED PROCTOR TEST
METHOD (MDD) IN ROADWAYS, ROADWAY SHOULDERS, ROADWAY PRISM AND DRIVEWAYS, AND 85 PERCENT MDD IN UNPAVED
AREAS. ALL PIPE ZONE COMPACTION SHALL BE 95 MDD.
6. CONCRETE BLOCKING FOR WATER MAINS SHALL BE DESIGNED, INSTALLED AND POURED IN PLACE IN ACCORDANCE WITH CITY OF
RENTON STANDARD DETAILS AND SPECIFICATIONS AND SHALL BE INSTALLED AT ALL VERTICAL AND HORIZONTAL BENDS, FITTINGS
AND BASE OF HYDRANTS. MEGA -LUGS (OR SIMILAR PRODUCT) MAY BE REQUIRED ON ALL MECHANICAL JOINTS IN ADDITION TO
CONCRETE BLOCKING.
ALL NEW WATER MAIN PIPES AND FITTINGS SHALL HAVE A FOAM PIPE PIG RUN THROUGH THEM PRIOR TO BEING FLUSHED,
DISINFECTED, AND TESTED. CLEANING, PRESSURE AND PURITY TESTING SHALL BE DONE IN THE PRESENCE OF AND UNDER THE
SUPERVISION OF A CITY OF RENTON UTILITY INSPECTOR. THE CONTRACTOR SHALL SUPPLY, INSTALL AND REMOVE PLUGS,
CORPORATION STOPS, BLOW -OFF ASSEMBLIES, AND THRUST RESTRAINT / BLOCKING FOR TESTING AND PURITY ACCEPTANCE. NO
CONNECTION SHALL BE MADE BETWEEN THE NEW MAIN OR BETWEEN THE NEW WET -TAP VALVE TO AN EXISTING MAIN UNTIL
THE NEW PIPING HAS BEEN FOAM -PIGGED, DISINFECTED, FLUSHED, AND PASSED BOTH PRESSURE AND PURITY TESTING.
8. NEW WATER MAINS INCLUDING SERVICE LATERALS SHALL BE TESTED AT A STATIC PRESSURE OF 150 PSI ABOVE WORKING
PRESSURE WITH A MINIMUM OF 225 PSI TEST PRESSURE FOR 120 MINUTES WITH A MAXIMUM OF 5 PSI PRESSURE DROP DURING
THE ENTIRE TEST PERIOD. UPON SATISFACTORY COMPLETION OF THE PRESSURE TEST, THE LINE SHALL BE DISINFECTED, FLUSHED,
AND THEN WATER SAMPLES SHALL BE TAKEN FOR PURITY TESTING BY THE PUBLIC WORKS INSPECTOR.
9. THE CONTRACTOR SHALL NOTIFY THE CITY OF RENTON WATER UTILITY AND MAINTENANCE DEPARTMENTS AT LEAST 10 WORKING
DAYS PRIOR TO MAKING CONNECTIONS TO THE EXISTING WATER SYSTEM. THE CONTRACTOR SHALL EXPOSE THE EXISTING WATER
MAIN AND FITTINGS AT THE CONNECTION POINT BEFORE ORDERING THE NECESSARY ADAPTORS AND FITTINGS REQUIRED FOR
THE FINAL CONNECTION. THE CONTRACTOR SHALL EXCAVATE, REMOVE ALL SURFACE MATERIALS, AND PROVIDE SHORING AND
ALL MATERIALS REQUIRED FOR THE CITY OF RENTON TO PERFORM THE CONNECTION TO THE EXISTING WATER SYSTEM. THE
CONTRACTOR SHALL PROVIDE AND INSTALL BACKFILL, CONCRETE BLOCKING, AND COMPLETE SURFACE RESTORATION.

FUNCTION
THE FUNCTION OF A PRESSURE REDUCING VALVE IS TO REDUCE
HIGH-WATER PRESSURES IN THE SERVICE CONNECTION TO AN
ACCEPTABLE RANGE OF 55 TO 75 PSI INSTALLATION OF A
PRESSURE REDUCING VALVE IS REQUIRED WHERE THE SERVICE
CONNECTION PRESSURE EXCEEDS 80 POUNDS PER SQUARE INCH
IN ACCORDANCE TO THE UNIFORM PLUMBING CODE.
INSTALLATION
THE PRESSURE REDUCING VALVE SHALL BE LOCATED ON
THE CUSTOMERS PROPERTY 'DOWNSTREAM" OF THE
METER BOX. RESPONSIBILITY FOR PROPER INSTALLATION,
OPERATION, AND MAINTENANCE OF THE VALVE SHALL BE
ASSUMED BY THE CUSTOMER. THREE POSSIBLE
CONFIGURATIONS FOR INSTALLATION OF THE VALVE ARE
SHOWN ABOVE. A BUILDING DEPARTMENT PLUMBING

GENERAL NOTES
1. The concrete vault shall be either a precast vault made by Utility Vault Co. or equal as
specified in the Standard Details, or shall be cast—in—place with 8" walls and slabs. All joints
shall be sealed so vault will remain watertight.
2. The vault cover shall be three 3' x 3' spring loaded hinged steel plate, lockable doors with
recessed lift handles, as made by Utility Vault Co. or approved equal.
3. Pipe supports shall be adjustable steel pipe support Stanchions bolted to floor of vault.
4. The vault shall contain one ladder constructed of galvanized steel. A detail plan of location
and construction shall be submitted to City prior to installation.
5. The exterior of the vault shall be sealed with two coats of ATCO Bitumastic No. 2221
6. The interior walls and ceiling of the vault shall be painted with two coats of Koppers
Ramuc Utility Enamel Flat, or approved equal. The floor shall not be painted.
7. The piping and equipment in the vault shall be given a complete field coat of Inertol Rust
Penetrating Primer No. 621 or approved equal. Two finish coats of Torex 800 Enamel, or
approved equal, shall be applied over the field coated primer.
8. The Standard PRV Station Site Plan shall be used for all new PRV station construction
except when limited right—of—way or existing buildings are restrictive. In such cases, and with
City approval, the in—line option may be used.
9. All isolation and zone valves outside the PRV station shall be provided with a valve box
when valves are 10" in size or smaller or a valve chamber when valves are 12" in size or
larger.
10. Pressure gauges shall be provided on both inlet and outlet pipes in the PRV vault.
Secondary gauges shall be mounted on the ceiling in easy view to be read from outside the
vault. Gauges shall read from 0-300 psi. Gauge installation shall include petcock between
pipe and gauge.
11. Joints on all valves and fittings outside the vault shall be mechanical joints unless
otherwise specified. Joints on valves and fittings inside vault shall be flanged or screwed as
specified. 12. Vault drain shall be piped to the nearest storm drain sewer or open drainage
ditch in lieu thereof. If no storm drain or drainage ditch is available, vault shall be
constructed with a sump on the outlet side of the vault. A sump pump shall be installed and
the discharge from the pump released onto a concrete pad outside the vault.
13. Cut 3" thick x 5" wide ethafoam 220 or equal to a length necessary to fit the size
of pipe installed and compressed into place. The contractor shall make sure the foam is
compacted tightly between pipe and vault wall with no voids. Lightly grout interior around pipe.
14. Pipe extending through vault shall be ductile iron, class 53, cement lined
