TESTING AND INSPECTION OF WATER MAINS, RECLAIMED WATER FORCE MAINS, WASTEWATER FORCE MAINS, AND GRAVITY SEWERS r 10.01 PRESSURE AND LEAKAGE TESTS OF UNDERGROUND PRESSURE PIPING r A. No hydrostatic testing will be permitted until as-built drawings have been submitted and approved by IRCDUS . — B . At the beginning of the test period , thoroughly clean all new pipelines by whatever means necessary , including flushing , to remove all dirt, stones, - pieces of wood , other material that may have entered the pipeline during the construction period , and all dirty and/or discolored water from the pipelines . If after this cleaning , any obstructions remain , they shall be removed . All debris cleaned from the pipelines shall be removed from the job site. Hydrostatic pressure and leakage tests shall conform to AWWA Standard Specifications C-605-94, or latest edition, for PVC pipe, with the exception that Specifications C-600-99 , or latest revision , for D . I . P, and - AWWA Standard Specifications. 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 . 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 for water mains and 100 psig for sewer - force mains. The Contractor shall provide temporary plugs and blocking necessary to maintain the required test pressure. Corporation cocks at least 1 inch in diameter, pipe riser and angle glove 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 part of testing . — C. The leakage test may 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 r regardless of total leakage as shown by test. Lines that fail to meet tests shall be repaired and re-tested as necessary until satisfactory test requirements are complied with . Defective materials, pipes , valves and accessories shall be removed and replaced . The pipe-lines 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 of a force pump to be furnished by the Contractor. Accurate means shall be provided for measuring the water required to maintain this pressure. The amount of — water required is a measure of the leakage . Testing shall be in accordance with the applicable provisions as set forth in Section 13 of AWWA Standard Specification c-600-99 , or latest revision . The allowable r 10 - 1
