No person shall uncover, make any connection with or opening into, use, alter or disturb any public sewer or appurtenance thereof, or dispose of wastes in any public sewer until a permit is obtained from the Town, and unless the connection and discharge of wastes has been shown to be in accordance with standards promulgated pursuant to the Act, and all regulations promulgated pursuant thereto, all pretreatment requirements, and any applicable standards of the State of New York, this chapter, or other local requirements.
There shall be two classes of building sewer permits: sanitary sewage service, and service to establishments discharging industrial wastes.
A. 
The application for sanitary sewer service shall describe the quantity and character of the waste to be discharged to the public sewer. The permit application shall be supplemented by any plans, specifications, or other information considered pertinent in the judgement of the Superintendent. A fee for sanitary sewer service permit and inspection shall be as set forth in § 135-56. This fee does not include any actions carried out by the Town under any other articles of this chapter.
B. 
Industrial waste dischargers shall, in addition to paying a permit fee equal to the amount set forth in § 135-56, make application in accordance with Article VI and Article VII of this chapter.
All costs and expense incident to the installation, connection and maintenance of the building sewer from the building to the public sanitary sewer connection shall be borne by the owner. If the Town performs the sewer tap to public sewer, a fee set forth in § 135-57 shall be paid to the Town upon completion of the tap. The owner shall indemnify the Town from any loss or damage that may directly or indirectly be occasioned by the installation of the building sewer. The connection to the public sanitary sewer shall be made under the supervision and in the presence of the Superintendent.
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 building sewer from the front building may be extended to the rear building and the whole considered as one building sewer. The Town assumes no obligation or responsibility for damage caused by or resulting from any single building sewer which serves two buildings.
Existing building sewers or house connections may be used in connection with new buildings only when they are found, on examination and test by the Superintendent, to meet all requirements of this chapter.

(3) 
All approved building sewer pipe to be bedded with four-inch (ten-centimeter) minimum compacted cushion of No. 1 or No. 1A broken stone under the pipe and up to the spring line (vertical midpoint of pipe) and covered at least six inches (15 centimeters) over top with compacted fine dirt and gravel by hand. Pipe shall be bedded carefully on the compacted material so that it does not ride on bells or joints. Backfill shall be free from stones larger than four inches (10 centimeters) in its greatest dimension. No slag material is to be allowed for house connections.
(4) 
In certain cases where the building sewer is being replaced, the Superintendent may allow the use of high-density polyethylene pipe to serve as the building sewer, by placing the polyethylene pipe inside the existing building sewer. In this situation, the pipe shall have a minimum SDR of 18 and shall conform to all applicable ASTM specifications for this material. The joints shall be thermal butt-fused between lengths of polyethylene pipe with the inner bead removal as per ASTM D-3261, latest revision. Joints between the polyethylene and other pipe shall be by a coupling acceptable to the Superintendent. Written approval of the Superintendent shall be obtained prior to proceeding with this type of installation. Application for permission shall be accompanied by a plan and a list of materials, sizes and depths.
E. 
Where any work is performed in street or highway right-of-way, the owner or his agent shall first obtain a permit from the proper state, county or Town highway authorities. Notice or request for inspection or final approval by highway authorities will be the responsibility of the owner or his agent. Utility companies are to be notified if work may affect their facilities.
F. 
All building sewers, at the discretion of the Superintendent, shall be air-tested and/or smoke-tested for leakage after installation. The test shall be conducted on all joints that would be exposed to infiltration of groundwater, surface water or other extraneous sources of unpolluted waters. The test shall be conducted from the point as close to the connection to the public sewer as possible, to the building plumbing system; and shall be carried out prior to backfilling the building sewer. Testing may also be carried out after backfilling if in the discretion of the Superintendent it is deemed necessary. The tests shall be conducted by the Superintendent or his authorized representative.
G. 
No backfill shall be placed until the work has been inspected to the satisfaction of the Superintendent. In the event of unstable soil conditions, special construction methods may be required but shall be approved by the Superintendent.
H. 
Each building sewer must be provided with a cleanout at house wall end, at bends greater than 45°, at road crossings and at least for every 100 feet (30.5 meters) of length; the openings to be a minimum of three inches (7.6 centimeters) above cellar floor or the ground surface outside buildings and shall be constructed of suitable material to prevent damage. Double hand traps are required when trap is in the wall or outside the building. No trap or vent shall be placed less than five feet (1.5 meters) from any window, door or ventilation intake.
I. 
Connection of the building sewer into the public sanitary sewer shall be by:
(1) 
Plastic, reinforced concrete, cast or ductile iron, ABS truss, or asbestos cement wye branch and/or riser installed at the time of construction of the sanitary sewer. All wye branches or risers shall comply with appropriate pipe specifications referenced elsewhere in this chapter. Joints shall be compatible with the above-referenced specifications for the type of pipe used and shall be approved by the Superintendent. All damaged branches shall be replaced. All connections shall be watertight. Concrete encasement of branches, or mortar joints, shall not be deemed watertight. Risers shall be braced against trench wall or supported otherwise.
(2) 
Saddle-type connections to the public sanitary sewers carried out by the Superintendent shall be made in a smooth, machine-drilled, round hole. The fitting used shall be made to insure that it will not protrude into the main sewer. The fitting shall fit the contour of the inside of the main sewer and be designed for the size of pipe into which construction is being made. One-eighth inch (0.3 centimeter) clearance shall be provided between the fitting and the hole, and between the shoulder of the fitting and face of the main pipe. These spaces shall be completely filled with waterproof joint material capable of withstanding any stress or strain likely to be encountered in normal sanitary sewer construction or maintenance. The fitting shall be manufactured of an aluminum alloy, stainless steel or other approved material and shall be capable of receiving all types of pipe approved for house service connections. It shall be held in place until adhesive is set.
J. 
All excavations for building or sanitary sewer installations 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 the work shall be restored in a manner satisfactory to the Superintendent. Ditches and culvert pipes for storm and surface water or other utilities disturbed during installation of sewers shall be replaced to their original condition. All driveways and parking areas shall be backfilled with select fill and thoroughly compacted.
K. 
Upon connection to the public sewer, any septic tank, cesspool and similar private wastewater disposal facility shall be abandoned, emptied and filled with a suitable material. Suitable material shall be as approved by the Superintendent.
L. 
In all buildings in which any building sewer is too low to permit gravity flow to the public sewer, sanitary sewage carried by such sewer shall be lifted by a method approved by the Superintendent and discharged to the public sewer at the expense of the owner.
The main building drain for any building shall be hung below the first floor and exit through the foundation wall at least 12 inches (30.5 centimeters) above the cellar floor. All devices producing wastewater installed in cellars shall discharge into the main building drain at a point within the building above the level of the exterior finished grade of the building sewer. Where a house trap is provided, the sewage ejector shall discharge on the sewer side of the trap.
No person shall make connection of: roof downspouts, foundation drains, areaway drains, sump pumps, floor drains such as garage or basement, 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. Any such connection now in existence shall be removed. A sump pump will be provided by the owner wherever required to carry ground and surface water to a natural outlet or storm sewer.
The connection of the building sewer into the public sewer shall conform to the requirements of this chapter and other applicable rules and regulations of the Town, with guidance from the procedures set forth in appropriate specifications of the ASTM or the WEF Manual of Practice No. 9. 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 Superintendent before installation.
The Superintendent shall be allowed to inspect the construction at any stage of completion and the applicant shall notify the Superintendent when the work is ready for final inspection, which notification shall be before any underground portions are covered and prior to connection to the Town sanitary sewer. The inspection shall be carried out within normal Town business hours. The actual connection to the public sanitary sewers shall be made by the Town or by the owner if prior approval is obtained by the Superintendent and the connection is carried out under the supervision of the Superintendent or his representative.
The Superintendent shall not issue a permit for any class of connection to the Town's wastewater treatment system unless there is sufficient capacity, not legally committed to other users, in the wastewater treatment system to convey and adequately treat the quantity of wastewater which the requested connection will add to the system.
