No unauthorized person(s) shall uncover, make any connections with or opening into, use, alter or disturb any public sewer or appurtenance thereof without first obtaining a written permit from the Township Superintendent.
A. 
There shall be three classes of building sewer permits:
(1) 
For residential service.
(2) 
For commercial service.
(3) 
For service to establishments producing industrial wastes.
B. 
In any case, the owner(s) or his agent shall make application on a special form furnished by the Township. The permit application shall be supplemented by any plans, specifications or other information considered pertinent in the judgment of the Township Superintendent. A permit fee as set forth in Article VI of this chapter shall be paid to the Township at the time the application is filed.
All costs and expenses incidental to the installation and connection of the building sewer shall be borne by the owner(s). The owner(s) shall indemnify the Township from any loss or damage that may directly or indirectly be occasioned by the installation of the building sewer.
The Township Committee may prohibit any person, firm or corporation from connecting into the public sewer system of the Township if, in the opinion of the Township Committee, the sewage or waste to be discharged into the system would be detrimental to the health, welfare or safety of the Township or the inhabitants thereof.
A separate and independent building sewer shall be provided for every building; except that where one building stands at the rear of another on an interior lot and no private sewer is available or can be constructed to the rear building through an adjoining alley, court, yard or driveway, the front building sewer may be extended to the rear building and the whole considered as one building sewer, but the Township does not and will not assume any obligation or responsibility for damage caused by or resulting from any such single connection aforementioned.
Old building sewers may be used in connection with new buildings only when they are found, on examination and test by the Township Superintendent, to meet all requirements of this chapter.
A. 
The size, slope, alignment and materials of construction of a building sewer and the methods to be used in excavating, placing of the pipe, jointing, testing and backfilling the trench shall all conform to the requirements of the building and plumbing codes or other applicable rules and regulations of this Township or the procedures set forth in appropriate specifications of the Water Pollution Control Federation Manual of Practice 9.
B. 
The connection of the building sewer into the public sewer shall conform to the requirements of the building and plumbing codes or any other applicable rules and regulations of the Township. All such connections shall be made gastight and watertight and verified by proper testing. Any deviation from the prescribed procedures and materials must be approved by the Township Superintendent and code officials before installation.
C. 
The applicant for the building sewer permit shall notify the Township Superintendent when the building sewer is ready for inspection and connection to the public sewer. The connection and testing shall be under the supervision of the Township Superintendent or his representative.
D. 
All excavations for building sewer installation shall be adequately guarded with barricades and lights so as to protect the public from hazard. Streets, sidewalks, parkways and other public property disturbed in the course of work shall be restored in a manner satisfactory to the Township or other public entity having jurisdiction of the involved public property.
E. 
Fixtures below grade.
[Added 8-5-1993 by Ord. No. 410]
(1) 
All structures having plumbing fixtures that are or will be below grade shall, in accordance with the provisions of the National Standard Plumbing Code of 1990, and additions and amendments thereto, install backwater or check valves for all said below-grade fixtures to prevent the backup of sewage into any structure with plumbing fixtures below grade from the trunk lines or sewer lines comprising the sewer system of the Township of Upper Deerfield.
(2) 
All structures with plumbing fixtures below grade that are now connected to the Upper Deerfield Township sanitary sewer system shall have 90 days from the date of the adoption of this subsection in which to install a backwater or check valve for their affected plumbing fixtures as required hereinabove.
Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by such building drain shall be lifted by an approved means and discharged to the building sewer. Upon request and where deemed reasonably justified based on sewage or waste flow generated, cost to connect and public health, welfare and safety, the Township Committee may waive the requirement of connection in those cases where the building drain is too low to permit gravity flow to a public sewer.
No person(s) shall make connection of roof downspouts, foundation drains, areaway drains or other sources of surface runoff or groundwater to a building sewer or building drain which, in turn, is connected directly or indirectly to a public sanitary sewer, unless such connection is approved by the Township Superintendent for purposes of disposal of polluted surface drainage.
[Added 4-5-1990 by Ord. No. 350]

D. 
Testing.
(1) 
All sewers are to be tested using low-pressure air after installation of the house connections. (For testing procedures, see Subsections E and F herein.)
(2) 
All PVC pipe installed shall be tested for deflection by pulling a mandrel through the pipe.
(3) 
The total vertical wall deflection of the PVC sewer pipe shall not exceed 7.5% of the inside pipe diameter.
(4) 
Prior to testing, the lines shall be cleaned and flushed.
(5) 
Final acceptance tests shall be conducted by the contractor and witnessed by a Township representative following pavement placement.
E. 
Leakage and testing.
(1) 
If an inspection of the completed sewer or any part thereof shows any manholes, pipes or joints which allow the infiltration of water in a noticeable stream or jet, the defective work or material shall be replaced or repaired as directed.
(2) 
Before final acceptance of the sewers, the contractor shall furnish all equipment and personnel to conduct an acceptable test using low-pressure air. Tests shall be conducted on all mainline sewers after the installation of the house connections and all utilities.
(3) 
The contractor shall first clean and flush all lines, and all debris flushed out shall be removed at each downstream manhole.
(4) 
All test plugs, gauges, an air compressor and personnel for conducting the acceptance test shall be furnished by the contractor. The test shall be conducted under the supervision of the Township Engineer or his duly appointed representative.
(5) 
The section of the line being tested shall be securely plugged at each manhole. All stoppers shall be adequately braced.
(6) 
For the acceptance test, air shall be slowly supplied to the plugged section of the pipe to be tested 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. At least two minutes shall be allowed for temperature stabilization before proceeding further. The back pressure of any groundwater caused by the water head above the invert of the pipe must be determined by a method approved by the Township Engineer. This back pressure must be added to the standard test pressures to compensate for the groundwater effect on the air test.
(7) 
The rate of air loss shall then be determined by measuring the time interval required for the internal pressure to decrease from 3.5 pounds per square inch to 2.5 pounds per square inch greater than the average back pressure of any groundwater that may submerge the pipe.
(8) 
The pipeline shall be considered acceptable when the drop of one pound per square inch pressure is not less than the holding time listed in the Air Test Table A herein, attached and made a part hereof this chapter.
(9) 
If the pipe installation fails to meet these requirements, the contractor shall determine at his own expense the source or sources of exfiltration, and he shall repair or replace all defective materials or workmanship. The complete pipe installation shall meet the requirement of this test.
F. 
Vertical deflection limitations.
(1) 
The contractor shall also furnish all equipment and personnel to conduct deflection testing on all PVC pipe installed. The total vertical wall deflection of the PVC sewer pipe shall not exceed 7.5% of the inside pipe diameter. Deflection testing shall not be conducted earlier than seven days after placement and compaction of the backfill.
(2) 
The vertical deflection shall be checked by manually pulling a "go, no-go" deflection testing mandrel through the pipe. The mandrel shall be specifically designed for this purpose, and the contractor shall submit shop drawings to the Township Engineer detailing the type of mandrel to be used. The mandrel shall be as manufactured by Armco, Inc., or equal and shall have the specified accuracy in all positions of rotations.
(3) 
The contractor shall conduct all deflection testing in the presence of the Township Engineer or his duly appointed representative. Should any pipe section exceed the maximum deflection specified, the contractor shall undertake any remedial action as required to reduce the deflection to within that limit.
