• 4M F (UGCO2660.FMT)aa i SECTION 02660 j TESTING AND INSPECTION OF WATER MAIMS l.o I PRESSURE AND LEAKAGE TESTS O UNDERGROUND PRESSURE 1 PIPING p., Hydrostatic pressure and leakage tests shall conform with Section 4 of the latest edition of AWWA C-600 specifications with the exception that the Contractor shall furnish all gauges, meters, pressure pumps and other equipment needed to test the line= Engineer or designated representative shall be present during all testing, televising and final inspections. B. The pressure required for the field hydrostatic pressure test shall be 1.5 times the normal working pressure at the point of testing, and not less than 1.25 times the working pressure at the highest point along the test section, but not less than 150 psi (100 psi for force main). The Contractor shall provide temporary plugs and blacking necessary to maintain the required test pressure. Corporation cocks at least 1 inch in diameter, pipe riser, and angle globe valves shall be provided at each pipe dead-end in order to bleed air from the line. Duration of pressure test shall be at least 2 hours. The cost of these items shall be included as a part of testing. C. The leakage test shall be conducted concurrently with the hydrostatic pressure test and shall be of not less than 2 hours duration. All leaks evident at the surface shall be repaired and leakage eliminated regardless of total leakage as shown by test. Lines that fail to meet tests shall be repaired and retested as necessary until test requirements are complied with. Defeetive materials, pipes, valves and accessories shall be removed and replaced, The pipelines shall be tested in such sections as may be directed by the Engineer by shutting valves or installing temporary plugs as required. The line shall be filled with water and all air removed, and the test pressure shall be maintained in the pipe for the entire test period by means ora force pump to be furnished by the Contractor. The amount of water required is a measure of the leakage. D, The Contractor must submit his plan for testing to the Engineer for review at least five (5) working days before starting the test. The Contractor shall remove and adequately dispose of all blocking material and equipment after comp!.etion and acceptance of the field hydrostatic test, unless otherwise directed by the Engineer. Any damage to the pipe coating shall be repaired by the Contractor. Lines shall be totally free and clean prior to final acceptance. 42660-1
