A. 
Before connecting to an existing main or Town service lateral, the resident or owner shall contact the Town Sewer Inspector and notify him of the work to be done. He shall obtain a written permit as required.
B. 
All building sewers shall be six inches in diameter, and no connection shall be made to the public sewer system except in the presence of the Town Sewer Inspector.
A house trap is optional and may be provided inside structures at the point where the sewer leaves the building. This shall be a four-inch minimum house trap, with two hand-hold cleanouts inside the house wall. These cleanouts shall be easily accessible. A three-inch or four-inch fresh air vent to the outside building wall shall be provided. A cleanout pipe is recommended outside the building on the building drain with a forty-five-degree connection and brought up to a point about three inches above grade. This cleanout shall be about two feet from the outside face of the foundation wall. If an outside cleanout is not provided, an inside cleanout shall be provided. The cleanout or backwater valve, if required, and the sewer line, to a point four feet outside the building wall, shall be approved material at least four inches in diameter.
A. 
Sewer pipe to be connected between the building drain and the Town service lateral at the property or easement line shall be as follows:
(1) 
Ductile iron water pipe, Class 50, latest ANSI A21.51 push-on joints.
(2) 
Cast-iron soil pipe, Service Class, latest ASTM A74; rubber gasket joints, latest ASTM C564.
(3) 
Solid wall ABS pipe, latest ASTM D-1788; six-inch solid wall, extra-strength SDR 35, latest ASTM D2751; solvent weld couplings.
(4) 
Vitrified clay pipe, extra strength 2400, latest ASTM C700; rubber ring compression joints, latest ASTM C425.
(5) 
PVC plastic pipe, latest ASTM 3034; rubber gasket joints, Class SDR 35.
(6) 
Asbestos-cement pipe, Class 2400, latest ASTM C428 or C644; rubber ring joints, latest ASTM D1869.
(7) 
Fiber wall pipe is not acceptable.
B. 
Appropriate and compatible fittings, connectors, joint lubricants and adhesives shall be used with all the above alternate materials. The Town Sewer Inspector shall require an air or water test on all building sewers of questionable air and water tightness.
A. 
The sewer pipe trench shall be excavated approximately one inch deeper than the inside bottom of the pipe, and the pipe shall be laid in a straight line on undisturbed soil. Where the trench is in rock, six inches beneath the invert shall be excavated, and in this space, a cushion of sand or pea stone shall be laid to give full support to the pipe for its full length. Where there is an existing six-inch capped Town service lateral, this cap shall be removed very carefully and airtight connection shall be made with the necessary adapter or fitting.
B. 
The building sewer pipe shall be tamped underneath to give it solid support for its full length. All pipe used shall be sound and free from cracks and defects. All joints shall be made air and water tight. The pipe shall be laid at a uniform pitch (at least 1/4 inch per foot of two-percent slope) to the building drain near the foundation, where an increase or other necessary fitting work shall be installed to provide a leakproof connection. Special permission may be obtained from the sewer district to use a lesser grade, which in no case shall be less than 1/8 inch per foot (or about one-percent grade). Backfilling shall be done with fine selected material and thoroughly tamped so that there will be no future settlement. There shall be at least two feet of backfill cover over the top of the pipe adjacent to the house and in excess of this amount where the pipe runs under driveways, sidewalks, etc. Where any discontinued sewer lateral is discovered, this line shall be properly capped.
[Amended 11-16-2020 by L.L. No. 10-2020]
Where it is necessary to tap the existing sanitary sewer in the street because no Town service lateral has been previously installed, it will be necessary to make these connections, excavations, backfillings, etc., in accordance with Town law or state or County Public Works Department regulations, as jurisdiction may apply. Work done in streets and other public rights-of-way shall be the responsibility of the property owner, including the installation of the service lateral to the property line. All of this work, including any permit fees or expenses, shall be paid for by the owner. See also § 136-55.
All work shall be done in accordance with these regulations. Notice must be given to the Town Sewer Inspector by the owner or his agent prior to the time the work is ready for inspection, and no part of the work shall be covered until it has been examined, tested and approved by the Town Sewer Inspector.
