No person 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 Town Board or the AHJ.
There shall be two classes of building sewer permits: for residential and commercial service and for service to establishments producing industrial wastes. In either case, the owner or his agent shall make application on a special form furnished by the Town. The permit application shall be supplemented by any plans, specifications or other information considered pertinent in the judgment of the Town Engineer. A permit and inspection fee shall be paid to the Town Clerk at the time an application is filed, such fees being established by resolution of the Town Board.
A separate and independent building sewer shall be provided for every building. Where building sewers are to serve multiple-dwelling structures, there shall be provided at least one separate building sewer for each group of eight apartments (or less).
Existing building sewers may be used in connection with new buildings only when they are found, on examination and test for the Town, to meet all requirements of this Part 3.
Building and street lateral pipe materials shall be one of the following:
A. 
Tar-coated, service grade, ductile iron soil pipe conforming to ASTM Specification A-74, Ductile Iron Soil Pipe and Fittings. All dimensions, weights, and markings of the pipe shall conform to the requirements of ANSI Designation A112.5.1, except spigot ends shall be "plain end" if gasket joints are used.
B. 
Polyvinyl chloride (PVC) pipe and fittings conforming to ASTM Specifications D3034-85b, Type PSM Polyvinyl Chloride (PVC) Sewer Pipe and Fittings or ASTM F789-85, Type PS-46 Poly (Vinyl Chloride) (PVC) Plastic Gravity Flow Sewer Pipe and Fittings. All pipe shall be suitable for gravity sewer service. Provisions shall be made for contraction and expansion at each joint with a rubber ring. The bell shall consist of an integral wall section stiffened with two PVC retainer rings which securely lock the solid cross-section ring into position. Minimum pipe stiffness (F/()y) at five-percent deflection shall be 46 psi when tested in accordance with ASTM Specification D2412.
C. 
Any part of the building or street lateral that is located within five feet of a water main or water service shall be constructed of ductile iron soil pipe encased in concrete and may be required by the Town where the building or street lateral is likely to be damaged by tree roots. If installed on fill or unstable ground, the building or street lateral shall be of ductile iron soil pipe, although other pipe material may be permitted if such pipe is uniformly supported on a poured concrete cradle approved by the Town. The distance between consecutive joints, as measured along the center line of the installed pipe, shall not exceed 10 feet, except under abnormal circumstances, in which case this dimension may be exceeded if approved by the Town. The size and slope of building or street laterals shall be subject to approval by the Town, but in no event shall the internal diameter be less than four inches, nor shall the slope of the pipe be less than 1/4 inch per foot.
At the point of connection of a street lateral to a main sewer, a standard wye fitting and sufficient one-eighth (45°) bend fittings shall be used. The wye fittings shall be installed so that flow in the "arm" shall transition smoothly into the flow in the public sewer. No lateral connection shall be made to the public sewer which permits the flow into the public sewer from the lateral to enter at right angles.
The size and slope of the building sewer shall be subject to the approval of the Town, but in no event shall the diameter be less than four inches, nor shall the slope of the pipe be less than 1/4 inch per foot.
The building sewer shall be brought to the building at an elevation as approved by the AHJ. No building sewer shall be laid parallel to and within three feet of any bearing wall which might thereby be weakened. The depth shall be sufficient to afford protection from frost, but in no event shall be less than four feet. The building sewer shall be laid at uniform grade and in straight alignment insofar as possible. Changes in direction shall be made only with properly curved pipe and fittings. The ends of the building sewers which are not connected to the building drain of the structure for any reason shall be sealed against infiltration by a suitable stopper, plug or other approved means.
In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sewage carried by such drain shall be lifted by approved mechanical means and discharged to the building sewer, except where a permit has been granted to the contrary under the provisions of Article XIV.
All excavations required for the installation of a building sewer shall be open trench work unless otherwise approved by the Town. Pipelaying and backfill shall be performed in accordance with Sections 3 through 6 of ASTM Specification C12, except that no backfill shall be placed until the work has been inspected.
A. 
All joints and connections shall be made gastight and watertight. No cement joints will be permitted.
B. 
Premolded gasket joints for hub and plain end cast-iron soil pipe shall be used and shall be a neoprene compression-type gasket which provides a positive double seal in the assembled joint. The gasket shall be a premolded one-piece unit, designed for joining the cast-iron hub and plain end soil pipe and fittings. The assembled joint shall be sealed by compression of the gasket between the exterior surface of the spigot and the interior surface of the hub. The joint shall be assembled following the manufacturer's recommendations, using acceptable lubricant and special pipe-coupling tools designed for that purpose. The plain spigot end shall be forced into the hub end of the pipe for the full depth of the hub itself. Lubricant shall be a bland, flax base, nontoxic material and shall not chemically attack the gasket material.
C. 
Joints for PVC sewer pipe shall follow the manufacturer's recommendations using properly designed couplings and rubber gaskets pursuant to the published information relating thereto and conforming to the applicable ASTM specification.
A. 
The connection of the building sewer into an existing public sewer shall be made at the main sewer line, except as provided under §§ 102-98 and 102-99. A cleanout to grade located at the public street right-of-way shall be included in said installation. The owner shall indemnify the Town from any loss or damage that may directly or indirectly be occasioned by the installation of this portion of the building sewer.
B. 
All subsequent costs and expense for the installation, maintenance or replacement of the remaining portion of the building sewer from the main sewer to the residence or place of business shall be borne by the property owner, including the cost of connecting the building sewer to the public sewer at the public street main sewer.
C. 
If, in the judgment of the Town, it is determined that a building sewer without a public street right-of-way cleanout needs repair or replacement, the Town can install, at the owner's expense, a cleanout at the public street right-of-way such that the portion of the building sewer located in the public street or right-of-way can be maintained independent of the remaining portion of the building sewer.
D. 
Any existing portion of the building sewer located in the public street or right-of-way which, upon examination by the Town, is determined to be in need of replacement will be replaced with a new portion with a public street right-of-way cleanout. The replacement portion shall be constructed by an approved contractor. The cost of constructing the replacement portion and cleanout will be at the owner's expense.
E. 
An interior cleanout fitting shall be provided for each building sewer at a readily accessible location, preferably just inside the building's basement wall. The fitting shall contain a 45° branch with removable plug or test tree and so positioned that sewer cleaning equipment can be inserted therein to clean the building lateral.
A. 
The applicant for the building sewer permit shall notify the Town when the entire building sewer and the portion of building drain extending from the building sewer to the outer face of the building wall is ready for inspection and connection to the public sewer. The connection shall be made under the supervision of the Town or its representative, and the method used shall receive the prior approval of the Town.
B. 
When trenches are opened for the laying of entire building sewer pipes and portions of building drains extending from the building sewer to the outer face of building walls, such trenches shall be inspected by the Town before the trenches are filled, and the plumber performing such work shall notify the Town when the laying of building sewer and said portion of building drain is completed. The filling of a trench before inspection is made will subject the plumber to whom a permit is issued to a penalty of $100 for each offense.
C. 
In case of a violation of any of the rules and regulations of the Town by a plumber, his journeymen plumbers or other persons of his employ, his permit (the plumber's) may be suspended or high recognition may be revoked by the Town.
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 the work shall be restored in a manner satisfactory to the Town.
When any building sewer is to serve a school, hospital or similar institutional or public building, or is to serve a complex of industrial or commercial buildings, or which, in the opinion of the Town, will receive sewage or industrial wastes of such volume or character that frequent maintenance of said building sewer is anticipated, then such building sewer shall be connected to the public sewer through a manhole. The Town shall determine if and where this type of connection to the public sewer is required. Connections to existing manholes shall be made as directed by the Town. If required, a new manhole shall be installed in the public sewer pursuant to § 102-100, and the building sewer connection made thereto as directed by the Town.
