Alignment - 0.l0 foot maximum deviation off true center line.

Grade - 0.02 foot maximum deviation above or below true grade.

Protection and Cleaning of Pipe Interior: Close the pipe end with a watertight stopper at the end of each days work. Clean sewer lines of all rocks, sticks, and other debris at the completion of construction.

Manhole Connection: Connection shall be watertight. Contractor must insure manhole gasket is uniformly seated around structure adapter. Extra precautions must be taken to prevent differential settlement between pipe and manhole.

Approval: Do not begin backfill until pipeline installation is approved in writing by the CO.

3.2 - Installation of Cleanouts Install cleanouts flush with surrounding ground as SHOWN ON DRAWINGS.

3.3 - Testing - Low Pressure Air Test Test all sections of the gravity sewer line, using the low pressure air test described below. Perform test in the presence of the CO.

Equipment: Supply all test equipment required including air test stand, test plugs, stop watch, calibrated test gage reading 0 to 15 psi maximum with 1/4 or 1/2 psi divisions, hoses and air compressor. Calibrate test gage with a standardized test gage and maintain calibration record for all gages in the test kit.

Timing of Test: Perform final acceptance air test after trench has been backfilled sufficiently to provide a minimum of 3 feet of cover over the pipe, or backfill is completed, whichever is less. Leave lateral ends exposed for testing prior to completing service connections.

Performance Required for Acceptance: Perform low pressure air test on plugged section of sewer line to determine the time required to lose 1.00 psi air pressure. To be acceptable, the time required to lose 1.00 psi must be equal to or greater than the time computed using the table and instructions below.
