Provide a minimum notice of 10 working days prior to startup and testing.// TESTING OF SANITARY SEWERS Gravity Sewers and Manholes (Select one of the following): Air Test: PVC Pipe, Uni-Bell Uni-B-6. Clean and isolate the section of sewer line to be tested. Plug or cap the ends of all branches, laterals, tees, wyes, and stubs to be included in the test to prevent air leakage. The line shall be pressurized to 28 kPa (4 psi) and allowed to stabilize. After pressure stabilization, the pressure shall be dropped to 24 kPa (3.5 psi) greater than the average of any groundwater above the sewer. The minimum test time shall be as specified in Uni-Bell Uni-B-6. Exfiltration Test: Subject pipe to hydrostatic pressure produced by head of water at depth of 900 mm (3 feet) above invert of sewer at upper manhole under test. In areas where ground water exists, head of water shall be 900 mm (3 feet) above existing water table. Maintain head of water for one hour for full absorption by pipe body before testing. During one hour test period, measured maximum allowable rate of exfiltration for any section of sewer shall be 11 L (3.0 gallons) per hour per 30 m (100 feet). If measurements indicate exfiltration is greater than maximum allowable leakage, take additional measurements until leaks are located. Repair and retest. Infiltration Test: If ground water level is greater than 900 mm (3 feet) above invert of the upper manhole, infiltration tests are acceptable. Allowable leakage for this test will be the same as for the exfiltration test. Pressure (Force) Mains: Test at 690 kPa (100 psi) for two hours. Leakage shall be per the following: L=J*D*P/4500 Where: L = Maximum Allowable Leakage in Gallons per Hour J = Number of Joints in Test Area D = Diameter of Pipe in Inches P = Average Test Pressure (Psi)
