PRELIMINARY

POLYPIG TESTING NOTES

1. POLYPIGGING SHALL BE PERFORMED ON ALL PIPING AS SHOWN ON THE PLANS AND SPECIFIED HEREIN:

1.1. POLYPIGGING LOCATIONS:

1.1.1. FORCE MAIN FROM NEW MECHANICAL VAULT TO SEPTIC LEACHFIELD.

2.MATERIALS

2.1. THE PIG SHALL BE OF POLYURETHANE MATERIAL WITHOUT ABRASIVE COATINGS OR STRIPS THAT

MIGHT DAMAGE THE INSIDE LINING OF THE PIPE. THE PIG DIAMETER SELECTED SHALL BE

APPROPRIATE FOR THE INSIDE DIAMETER OF THE PIPE AND SHALL BE OF A MATERIAL, SIZE, AND

CONFIGURATION RECOMMENDED BY THE PIG MANUFACTURER FOR USE IN CLEANING AND

REMOVING ALL LOOSE DEBRIS FROM INSIDE THE PIPE. A DOUBLE DISH SHAPED PIG SHALL BE USED

UNLESS PREVIOUSLY APPROVED IN WRITING BY THE OWNER. THE MATERIAL, DENSITY, AND SIZE OF

THE PIG SHALL BE SUCH THAT IT WILL NOT DAMAGE THE INTERIOR LINING OF THE PIPE. THE EXACT

INSIDE DIAMETER OF THE PROPOSED PIPE SHALL BE MEASURED TO THE NEAREST 0.10 INCH AND

REPORTED TO THE PIG MANUFACTURER FOR MANUFACTURING TO EXACT PIPE TOLERANCES.

2.2. THE PIG MUST BE CAPABLE OF SUCCESSFULLY PASSING THROUGH THE PIPE WITH DEFLECTIONS OF

90 DEGREES OR LESS, TEES AND OPEN VALVES WITHOUT DAMAGE TO THE PIPE OR PIPE LINING.

3. EXECUTION

3.1. RUN THE PIG FROM THE INSERTION POINT TO THE REMOVAL POINT AS RECOMMENDED BY THE PIG

MANUFACTURER. DURING THE PIGGING PROCESS, WATER USAGE, AND PRESSURE FLUCTUATIONS IN

THE SYSTEM SHALL BE MEASURED. AT A MINIMUM, FLOW AND PRESSURE READINGS MUST BE

RECORDED AT 30 SECOND INTERVALS. ALL OTHER PRESSURE FLUCTUATIONS OR JUMPS SHALL BE

RECORDED AND NOTED ON A RECORD SHEET. PRESSURE INCREASES MAY INDICATE THE PRESENCE

OF A BLOCKAGE. THE CONTRACTOR SHALL BE RESPONSIBLE FOR ENSURING PRESSURE SURGES DO

NOT EXCEED THE RATED WORKING PRESSURE OF THE PIPING, FITTINGS, AND APPURTENANCES. ANY

DAMAGES TO THE MAIN FROM PRESSURE SURGES DURING POLYPIGGING SHALL BE PAID FOR AND

REPAIRED BY THE CONTRACTOR.

3.2. THE TIME AND PRESSURE LOG SHALL BE SUBMITTED TO THE OWNER FOLLOWING THE POLYPIGGING

PROCESS FOR THEIR MAINTENANCE RECORDS INCLUDING; 1) THE NUMBER OF PIG PASSES AND

NUMBER OF PIGS USED; 2) OBJECTS FOUND DURING FLUSHING AND THEIR APPROXIMATE

LOCATIONS IN THE WATER MAIN; 3) APPROXIMATE PIG VELOCITY AND LOCATION; 4) PRESSURE

ZONE OF SYSTEM; 5) FLUSHING TIME BEFORE WATER APPEARED CLEAR; AND 6) DATE.

4.CLEANING

4.1. THE PIG SHALL BE INSPECTED UPON REMOVAL TO DETERMINE WHETHER OR NOT IT HAS BEEN

DAMAGED FROM PASSING OVER OR AROUND A LARGE OBJECT THAT IS WEDGED INSIDE THE PIPE.

IF THE PIG IS DAMAGED, THE LOCATION OF THE BLOCKAGE THAT CAUSED THE DAMAGE SHALL BE

IDENTIFIED USING THE PRESSURE LOG. THE BLOCKAGE SHALL THEN BE REMOVED AND THE PIPELINE

INSPECTED AND REPAIRED TO A LIKE NEW CONDITION. AFTER THE BLOCKAGE(S) HAS BEEN

REMOVED AND THE PIPELINE REPAIRED, A SECOND PIG SHALL RUN THROUGH THE LINE USING THE

SAME PROCESS AND PROCEDURES IDENTIFIED IN THE PREVIOUS PARAGRAPHS.

4.2. DO NOT ALLOW THE SWABBED DEBRIS TO REENTER THE PIPE FOLLOWING A POLYPIG PASS. PIPE

ENDS SHALL BE CAPPED OR FITTINGS REPLACED TO PREVENT DEBRIS FROM ENTERING THE CLEANED

PIPE. ANY FITTINGS OR VALVES NOT CAPABLE OF PASSING A POLYPIG SHALL BE FLUSHED OR SWEPT

CLEAN. AFTER THE PIG HAS BEEN REMOVED, WATER SHALL BE FLUSHED THROUGH THE PIPING

SYSTEM UNTIL THE WATER IS CLEAR AND APPROVED IN WRITING BY THE OWNER.

OR REPLACE THE GASKET, REINSTALL OR RE-TIGHTEN THE BOLTS AND NUTS, AND RETEST THE

JOINTS. REPLACE THE GASKET IF DAMAGED.

2.10.5. VERIFY THE SIZE, MATERIAL, AND LOCATION OF THE EXISTING MAIN AT THE CONNECTION POINT

PRIOR TO INSTALLING THE NEW SEWER FORCE MAIN.

DEMONSTRATE THE INTEGRITY OF THE FINISHED INSTALLATION FOR THE APPROVAL OF THE OWNER

AND ALL AGENCIES HAVING JURISDICTION.

3.2. BACKFILL THE PIPELINE TRENCH SUFFICIENTLY TO PREVENT MOVEMENT OF THE PIPE UNDER PRESSURE.

ALL THRUST BLOCKS SHALL BE IN PLACE AND SUFFICIENTLY CURED TO REACH DESIGN STRENGTH

BEFORE TESTING. FURNISH, INSTALL, AND REMOVE TEMPORARY BLOCKING WHERE PERMANENT

BLOCKING IS NOT REQUIRED AND REMOVE IT AFTER TESTING.

3.3. ALL PUMPS, GAUGES, PLUGS, SADDLES, CORPORATION STOPS, MISCELLANEOUS HOSE AND PIPING, AND

TEST AND INSPECTION NOTES

1. TESTS AND INSPECTION

1.1. HYDROSTATIC PRESSURE TESTING

1.1.1. COVER ANY EXPOSED PRESSURIZED PVC OR HDPE PIPE TO PROTECT FROM DIRECT SUNLIGHT

IF THE AIR TEMPERATURE IS ABOVE 70°F.

1.1.2. TEST ALL PIPELINES AND APPURTENANCES UNDER A HYDROSTATIC TEST PRESSURE EQUAL

TO THAT SPECIFIED UNDER DIVISION 1.81.40 OF THESE SPECIFICATIONS. IF NOT STATED, THE

HYDROSTATIC TESTING PRESSURE SHALL BE 150 PSI OVER WORKING PRESSURE OR 250 PSI,

WHICHEVER IS GREATER, MEASURED AT THE LOW POINT OF THE TEST SECTION. THE OWNER

HAS THE RIGHT TO REQUIRE MORE STRINGENT TEST CRITERIA THAN STATED IN THIS

SPECIFICATION OR IN THE PRESSURE RATING SECTION IF IT IS DETERMINED THAT FIELD

CONDITIONS WARRANT SUCH MEASURES.

1.2. THE OWNER WILL FURNISH THE WATER NECESSARY TO FILL THE PIPELINES AND FOR TESTING AT

A TIME OF DAY WHEN SUFFICIENT QUANTITIES OF WATER ARE AVAILABLE FOR NORMAL SYSTEM

OPERATION.

1.3. FILL THE PIPELINES WITH WATER AND ALLOW TO STAND UNDER PRESSURE FOR A MINIMUM OF

24 HOURS TO ALLOW AIR TO ESCAPE AND ALLOW THE LINING OF THE PIPE TO ABSORB WATER.

THE CONTRACTOR IS RESPONSIBLE FOR THE PROPER DISPOSAL OF ANY WASTE, INCLUDING

WATER.

1.3.1. FITTINGS AND SECTIONS OF PIPE THAT CANNOT BE PRESSURE TESTED, SUCH AS

CONNECTIONS TO THE EXISTING SYSTEM, SHALL BE LEFT EXPOSED FOR A VISUAL

INSPECTION UNDER SYSTEM PRESSURE. ANY VISIBLE LEAKAGE SHALL BE CORRECTED BY THE

CONTRACTOR TO THE SATISFACTION OF THE OWNER REGARDLESS OF THE ALLOWABLE

LEAKAGE SPECIFIED HEREIN. SHOULD THE TEST SECTION FAIL TO MEET THE SPECIFIED

PRESSURE TEST SUCCESSFULLY, THE CONTRACTOR SHALL LOCATE AND REPAIR THE DEFECTS

AND THEN RETEST THE PIPELINE AT THEIR EXPENSE.

1.3.2. PRIOR TO CALLING OUT THE OWNER TO WITNESS THE PRESSURE TEST, THE EQUIPMENT

SHALL BE COMPLETELY SET UP, READY FOR OPERATION, AND HAVE SUCCESSFULLY

PERFORMED THE TEST TO ASSURE THAT THE PIPE IS IN A SATISFACTORY CONDITION. THE

OWNER SHALL WITNESS THE TEST; IF THE TEST DOES NOT PASS INSPECTION FOR ANY

REASON, ADDITIONAL TRIPS REQUIRED TO WITNESS ANOTHER TEST SHALL BE DONE AT THE

CONTRACTOR'S EXPENSE.

1.3.3. BEFORE APPLYING THE SPECIFIED TEST PRESSURE, AIR SHALL BE EXPELLED COMPLETELY FROM

THE PIPE, VALVES, AND APPURTENANCES.

1.3.4. THE TEST SHALL BE ACCOMPLISHED BY PUMPING THE MAIN UP TO THE REQUIRED

PRESSURE; STOP THE PUMP FOR A MINIMUM OF 15 MINUTES UP TO A MAXIMUM OF 60

MINUTES AS DIRECTED BY THE ENGINEER, AND THEN PUMP THE MAIN UP TO THE TEST

PRESSURE AGAIN. DURING THE TEST, THE SECTION BEING TESTED SHALL BE OBSERVED FOR

VISIBLE LEAKAGE. A CLEAN CONTAINER SHALL BE USED FOR HOLDING WATER FOR PUMPING

PRESSURE ON THE MAIN BEING TESTED. THIS MAKEUP WATER SHALL BE STERILIZED BY THE

ADDITION OF CHLORINE TO A CONCENTRATION OF 50 MG/L (PPM).

1.3.5. SECTIONS TO BE TESTED SHALL NORMALLY BE LIMITED TO 1,500 FEET. THE OWNER MAY

REQUIRE THAT THE FIRST SECTION OF PIPE, NOT LESS THAN 1,000 FEET IN LENGTH,

INSTALLED BY EACH OF THE CONTRACTOR'S CREWS BE TESTED IN ORDER TO QUALIFY THE

CREW AND/OR THE MATERIAL. PIPE LAYING SHALL NOT CONTINUE MORE THAN AN

ADDITIONAL 1,000 FEET UNTIL THE FIRST SECTION HAS BEEN TESTED SUCCESSFULLY.

1.3.6. SECTIONS TO BE TESTED SHALL BE ISOLATED AND PUMPED TO TEST PRESSURE. TEST

PRESSURE SHALL BE SUSTAINED FOR A MINIMUM OF 60 MINUTES WITH LESS THAN

2-PERCENT (5 PSI) LOSS IN PRESSURE THROUGHOUT THE TEST DURATION WITH OWNER

PRESENT AND ON SITE THROUGHOUT TEST DURATION. IF TEST RESULTS DO NOT COMPLY,

CONTRACTOR SHALL REPAIR LEAKS AND RETEST UNTIL TESTING IS PASSED IN PRESENCE OF

OWNER. OWNER MAY BLEED OFF PRESSURE FROM PUMP TO PIPING CONNECTION ONCE

TEST IS PASSED TO VERIFY SYSTEM PIPING WAS TESTED.

2. VALVE TESTING

2.1. ALL VALVES SHALL BE PRESSURE TESTED. DO NOT EXCEED THE RATED WORKING PRESSURE OF

THE VALVE WHEN OPERATING THE VALVE. BLEED OFF TEST PRESSURE PRIOR TO OPERATING.

CHECK ALL VALVE BONNET FASTENERS FOR TIGHTNESS.

2.2. PRE-INSTALLATION

2.2.1. ALL BURIED VALVES SHALL BE PRESSURE TESTED OUTSIDE THE TRENCH. GATE VALVES SHALL

BE TESTED ON ONE SIDE OF THE CLOSED SEAT. BUTTERFLY AND ECCENTRIC VALVES MUST

BE TESTED ON BOTH SIDES OF THE CLOSED SEAT.

2.3. POST-INSTALLATION

2.3.1. TEST ALL VALVES FOR WATER TIGHTNESS UNDER DIFFERENTIAL WORKING PRESSURE. TO

PERFORM THIS TEST, PRESSURIZE PIPE SECTION WITH VALVE IN PLACE, CLOSE VALVE AND

RELIEVE PRESSURE ON SEAT SIDE OF THE VALVE. THE VALVE SHALL NOT PASS WATER

DURING A 5-MINUTE TEST PERIOD.

2.3.2. OPERATE ALL VALVES AT LEAST ONCE FROM CLOSED-TO-OPEN-TO-CLOSED POSITIONS WHILE

VALVE IS UNDER WORKING (NOT TEST) PRESSURE.
