7.2 HYDROSTATIC (LEAKAGE:) TEST: AFTER COMPLETION OF THE PIPELINE INSTALLATION, THE LINE SHALL BE
TESTED UNDER THE HYDROSTATIC PRESSURE TEST OF 150 PSI FOR A PERIOD OF NOT LESS THAN 4 HOURS
FOR EACH SECTION OF PIPE TESTED. THE PRESSURE SHALL BE MAINTAINED BY RESTORING THE TEST
PRESSURE WHENEVER IT FALLS AN AMOUNT OF 25 PSL AT THE CONCLUSION OF THE 4 HOURS, THE TEST
PRESSURE SHALL BE RESTORED AND ALL WATER USED DURING THE TESTS SHALL BE ACCURATELY MEASURED
TO DETERMINE THE ACTUAL LEAKAGE.
7.2.1 THE CONTRACTOR SHALL PROVIDE SUITABLE CALIBRATED TANKS FOR MEASUREMENT OF LEAKAGE AND
SHF+LL FURNISH NECESSARY BULKHEADS, PIPING, PUMPS, POWER, LABOR, AND SHALL PERFORM ALL WORK
REQUIRED FOR FILLING THE PIPELINE AND FOR MAINTAINING THE REQUIRED WATER PRESSURE. THE
DEPARTMENT OR INSPECTOR WILL PROVIDE CALIBRATED GAGES AND WILL MAKE NECESSARY READINGS.
7.2.2 THE CONTRACTOR, AT HIS OWN EXPENSE SHALL MAKE ALL NECESSARY REPAIRS OF THE WATER SYSTEM
UNTIL THE PIPE IS FOUND TO BE SATISFACTORY.
7.2.3 ALLOWABLE 1_1=AKAGE RATE: RESOARDLESS OF THE RATE OF LEAKAGE, A DETECTABLE LEAKAGE POINT
SOURCE SHALL BE =1XED. THE FOLLO`ING ARE MAXIMUM ACCEPTABLE LEAKAGE RATES FOR A.C. AND P.V.C.
PIP1= OVER A 24 HOUR PERIOD. P.V.C. AND MOLECULARY ORIENTED P.V.C. PIPE: MAXIMUM ACCEPTABLE
LEAKAGE RATE IS 10 GALLONS PER DAY PER INCH PIPE DIAMETER PER MILE OF PIPE OVER A 24 HOUR
PERIOD.
7.3 DISINFECTION OF WATER LINES: AFTER HYDROSTATIC TESTING HAS BEEN COMPLETED, THE ENTIRE NEWLY
CONSTRUCTED WATER SYSTEM, INCLUDING PIPE, VALVES, FITTINGS, HYDRANTS, AND OTHER ACCESSORIES
SHALL BE DISINFEC TED IN ACCORDANCE WITH AWWA C-601 AND THE MOST RECENT STANDARDS AND
SPECIFICATIONS FOR DOMESTIC WATEF' SYSTEMS FOR THE CITY OF BAKERSFIELD.
7.5 FIRE FLOW TEST: THE CITY OF BAKERSFIELD FIRE DEPARTMENT WILL TEST NEWLY CONSTRUCTED WATER
SYSTEMS TO DETERMINE IF MINIMUM STANDARDS FOR THE FIRE FLOW HAVE BEEN MET.
7.6 COSTS FOR TESTING: THE CONTR NCTOR SHALL BE RESPONSIBLE FOR ALL COSTS ASSOCIATED WITH THE
VARIOUS ACCEPTANCE TESTS AND ANY NECESSARY REPAIRS, EXCEPT AS OTHERWISE STATED IN THESE
SPECIFICATIONS.
Q±SITE WATER SPECIFICATIONS

5. THE MINIMUM WIDTH OF TRENCH SHALL BE THE OUTSIDE DIAMETER OF THE PIPE PLUS 12". A
MINIMUM OF 6" OF CLEARANCE SHALL, BE PROVIDED FROM THE OUTSIDE FACE OF THE PIPE TO
THE TRENCH WALL. WATER LINES ANC SERVICES SHALL HAVE A MINIMUM OF 30" OF COVER
FROM THE TOP OF PIPE TO FINISHED GRADE. THE BOTTOM OF THE TRENCH SHALL BE
EXCAVATED TO THE ESTABLISHED GRi0E UNE OF THE PIPE AND SHALL BE SMOOTH, EVEN AND
FLAT FOR THE ENTIRE WIDTH OF THE TRENCH. AT EACH JOINT THE BOTTOM OF THE TRENCH
SHALL BE RECESSED IN SUCH A MANNER AS TO RELIEVE THE PIPE BELL OR COUPLING OF ALL
LOAD AND TO ENSURE CONTINUOUS E EARING ALONG THE PIPE BARREL.
6. BACKFILL SHALL BE INITIALLY PLACED AND COMPACTED FROM THE PIPE BED TO THE SPRING
