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) MAYBE REQUIRED ON ALL MECHANICAL JOINTS IN ADDITION TO
CONCRETE BLOCKING.
7. 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.
B. 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
