A. 
All construction of sewage systems shall be under the jurisdiction of the Township, either directly, or through inspectors under the supervision of the Township Engineer.
(1) 
The Township Engineer and the applicant's engineer shall enforce compliance with the approved plans and specifications.
(2) 
The Township Engineer shall have the authority to have work discontinued in the event of non-compliance.
(3) 
The applicant shall furnish the name of the occupant, the street address, and lot and block number to the Township at least two weeks prior to a request for the certificate of occupancy from the Construction Code Official to assure that the lateral inspection has been accomplished, and all fees have been paid.
(4) 
No sewer connections shall be made to the appropriate street main whether tested or not unless under the supervision and inspection of the representative for the Township. Clean-out installations are subject to review and approval by the licensed operator prior to the issuance of a certificate of occupancy.
B. 
A temporary, leak proof bulkhead type plug shall be installed in the upstream (inlet) side of the manhole furthest downstream in any sewer main or branch under construction and shall remain intact and unloosened until permission is received from the Township to remove same. This permission will not be granted until each section of the sewer has been cleaned and flushed in a manner acceptable to the Township.
A. 
All sewer mains shall be subjected to either an infiltration or exfiltration test, or under special circumstances to a low pressure air test. Exfiltration tests shall be conducted in lieu of infiltration tests when the pipe has been laid above the groundwater level. Infiltration tests shall be used only when the groundwater level is above the crown of the sewer and completely surrounds the pipe during the period of testing. The tests shall be performed between two manholes or as otherwise directed by the Engineer for the Township and shall include all related sewerage facilities including house connections.
B. 
The contractor shall furnish all labor, materials and equipment necessary for the testing.
C. 
Exfiltration tests shall be under at least a four-foot head or a pressure corresponding to a head equal to the depth of the lower manhole of the section under the test.
D. 
Allowable infiltration or exfiltration shall not exceed a rate of 100 gallons per mile, per inch of diameter of sewer, per 24 hours.
E. 
In order to ensure that there shall be no gushing or spurting streams entering the sewer, the contractor shall be held responsible for water-tightness of the line, shall satisfactorily repair all joints and other parts not sufficiently watertight and then shall make additional tests of the infiltration or exfiltration until the test results conform to the requirements given herein and until all visible leaks are eliminated.
F. 
Detailed criteria for testing, and special requirements, are included in the Township's "Specifications for Sewer Construction."
G. 
Sewer pipe cleaning. After testing and before final acceptance of the work, the contractor shall clean the entire sewer system, unless such procedures are specifically waived by the Township. The cleaning method employed shall utilize Jet-Vac Sewer Cleaner or approved equal, and all material collected at the downstream end of the system shall be removed by vacuuming, and shall not pass downstream.
H. 
Upon completion and visual acceptance, all lines are to be internally examined using a television camera, to check for improper joints, off-grade pipe, and damaged pipe. The inspection is to be witnessed on a monitor screen by Township personnel, or video tape is to be furnished, as approved.
