SECTION 02660 <br /> TESTING AND INSPECTION OF WATER MAINS <br /> 1 . 01 PRESSURE AND LEAKAGE TESTS OF UNDERGROUND PRESSURE <br /> PIPING <br /> A. Hydrostatic pressure and leakage tests shall conform with Section 4 of <br /> the latest edition of AWWA C-600 specifications with the exception that <br /> the Contractor shall furnish all gauges , meters , pressure pumps and other <br /> equipment needed to test the line . Engineer or designated representative <br /> shall be present during all testing , televising and final inspections . <br /> B . The pressure required for the field hydrostatic pressure test shall be 1 . 5 <br /> times the normal working pressure at the point of testing , and not less <br /> than 1 . 25 times the working pressure at the highest point along the test <br /> section , but not less than 150 psi ( 100 psi for force main . ) The Contractor <br /> shall provide temporary plugs and blocking necessary to maintain the <br /> required test pressure . Corporation cocks at least 1 inch in diameter, <br /> pipe riser, and angle globe valves shall be provided at each pipe dead- <br /> end in order to bleed air from the line . Duration of pressure test shall be <br /> at least 2 hours . The cost of these items shall be included as a part of <br /> testing . <br /> C . The leakage test shall be conducted concurrently with the hydrostatic <br /> pressure test and shall be of not less than 2 hours duration . All leaks <br /> evident at the surface shall be repaired and leakage eliminated <br /> 1 regardless of total leakage as shown by test . Lines that fail to meet tests <br /> shall be repaired and retested as necessary until test requirements are <br /> complied with . Defective materials , pipes , valves and accessories shall <br /> be removed and replaced . The pipelines shall be tested in such sections <br /> as may be directed by the Engineer by shutting valves or installing <br /> temporary plugs as required . The line shall be filled with water and all air <br /> removed , and the test pressure shall be maintained in the pipe for the <br /> entire test period by means of a force pump to be furnished by the <br /> Contractor. The amount of water required is a measure of the leakage . <br /> D . The Contractor must submit his plan for testing to the Engineer for review <br /> at least five (5 ) working days before starting the test. The Contractor <br /> shall remove and adequately dispose of all blocking material and <br /> equipment after completion and acceptance of the field hydrostatic test, <br /> unless otherwise directed by the Engineer. Any damage to the pipe <br /> coating shall be repaired by the Contractor. Lines shall be totally free and <br /> clean prior to final acceptance . <br /> E . The Engineer or the Engineer's representative must be present during <br /> testing . <br /> F . No thrust blocks shall be backfilled until inspected by p IRCDUS inspectors . <br /> 02660 - 1 <br /> FAUtilities\UTILITY - ENGINEERING\WTP - North RO\N RO Brine Line Discharge - UCP#2208\BID DOCUMENTS North County <br /> ' RO\BID DOCUMENTS\02660 Testing and Inspection of Water Mains . doc <br />
