TESTING AND INSPECTION OF WATER MAINS , RECLAIMED WATER FORCE MAINS , WASTEWATER FORCE MAINS , AND GRAVITY SEWERS 10 . 01 PRESSURE AND LEAKAGE TESTS OF UNDERGROUND PRESSURE PIPING 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 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 10 - 1
