A.    The contractor shall furnish all facilities and personnel for conducting the air-acceptance test under the observation of the engineer. The equipment and personnel shall be subject to the approval of the engineer.

B.    The pipe installation shall be tested with low-pressure air. Air shall be slowly supplied to the plugged pipe installation until the internal air pressure reaches 4.0 pounds per square inch greater than the average back pressure of any groundwater that may submerge the pipe, if:

1.    The total rate of air loss from any section tested in its entirety between manhole and cleanout structures does not exceed 2.0 cubic feet per minute; or

2.    The section under test does not lose air at a greater rate than 0.0030 cubic feet per minute per square feet of internal pipe surface.

C.    If the pipe installation fails to meet these requirements, the contractor shall determine at his own expense the source or sources of leakage, and he shall replace all defective materials or workmanship or repair them to the satisfaction of the engineer. The extent and type of repair which may be allowed as well as results shall be subject to the approval of the engineer. The completed pipe installation shall then be retested and required to meet the requirements of this test.

D.    Side sewers may, upon approval of the city building inspector, be tested for visible leakage before backfilling by inserting a removable test plug at the lower end of the line and filling the line with water to its highest point. The contractor shall make this test before calling for inspection so that the inspector can observe and approve the installation in one visit. A tee shall be provided in the sewer for insertion of the plug and shall be capped tightly and securely against back pressure upon completion of the test.

(Ord. 78 § 21, 1972)

13.28.210 Exfilteration test.

A.    Exfilteration test shall be used only if specifically authorized by the engineer. Leakage, unless otherwise provided for in the special provisions, shall not exceed the provisions that follow. Leakage after backfill shall be no more than five tenths gallon per hour per inch of diameter per one hundred feet of sewer pipe, with a minimum test pressure of six feet of water column above rounding ground water table whichever causes the greater head on the pipe. The length of pipe tested shall be limited so that the pressure on the invert of the lower end of the section tested shall not exceed sixteen feet of water column. For each increase in pressure of two feet above the basic six feet measured above the crown at the lower end of the test section, the allowable leakage shall be increased by ten percent.

B.    Side sewers shall also be tested for their entire length from the public sewer in the street to the connection with the building plumbing. Testing of side sewers shall be as required by the local sanitary agency. Within the boundaries of the city, in no case shall testing be less thorough than that of filling the pipe with water before backfill and visually inspecting the exterior for leakage. The decision of the engineer as to acceptance of the side sewer shall be final.

C.    The contractor may fill the pipe any time up to twenty-four hours prior to the time of exfilteration testing to permit normal absorption into the pipe walls.

D.    It shall be the contractor’s responsibility to determine the level of the water table at each manhole. This may be done by installing a pipe nipple through the manhole wall or by some other means satisfactory to the engineer.

Allowable Leakage in Gallons per 100 Linear Feet of Sewer per Hour (Based on 0.5 gph/100 feet of pipe per inch of diameter plus 10% for every 2 feet of head above 6 feet)
