A separate and independent building sewer shall be provided for every building. 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 does not and will not assume any obligation or responsibility for damage caused by or resulting from any such single connection aforementioned. The rights appurtenant to such single connection or extension from a front building to a rear building shall be recorded with each of the respective deeds.
An investigation of private sewers or drains and sewer service connections within the street limits laid prior to November 19, 1985, may be made at the discretion of the Director to determine if such private sewers and sewer connections are properly located, laid at suitable gradient, in good condition, with proper and suitable appurtenances and in every way satisfactory to the Director. If, in the opinion of the Director an existing service connection is significantly deficient in gradient, condition or appurtenances, he may require the reconstruction of all or parts of the service connection. Such reconstruction shall be completed within six months of the official notification of the owner.
All costs and expenses incident to the installation and connections or the reconstruction to correct deficiencies of the building sewer shall be borne by the owner. 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.
Any person developing a plat of land in the Town shall at his own expense install wastewater works including sewer lines and service stubs with wyes in such plat and shall connect the same with the existing sewer system according to Town-approved plans where the system is within 200 feet (60.6 m) of the subdivision. Where the existing sewer system is beyond 200 feet (60.6 m) but the plat is in its entirety or in part located in an area where there are immediate plans to provide public sewers, the developer shall at his own expense install wastewater works including sewer lines and service stubs with wyes in such manner as to make future connection with the Town's sewer system feasible. All work shall be carried out in accordance with the standard construction details available from the Town Clerk. The developer may, at his option, also build private wastewater disposal systems in total compliance with division 2 of this chapter. If the proposed development is located in an area where there are no immediate plans to provide public sewers, each lot shall be designed insofar as feasible to permit the location of an individual sewage disposal system between the street and the house. Connection to the public sewer system shall be in compliance with the terms and conditions set forth in the following:
A. 
The entire cost of the installation of all wastewater works to serve any such plat or any part thereof, shall be paid by the developer. The entire cost shall include the cost of all engineering services, both preliminary to and during the actual installation of such sewer pipes, and other works, and the costs of all materials, services, labor and supplies for constructing and laying out sewers and connecting the same with the sewer system.
B. 
The developer, before proceeding with the installation of sewer lines in any such plat or any part thereof, shall submit plans and specifications to the Director relative to the proposed construction in accordance with the Standard Construction Details available from the Town Clerk. The proposed plans shall include a minimum diameter transmission/collector line as determined by the Director to allow sufficient capacity to carry sewage flows from abutting properties and from properties abutting properties. Unless otherwise approved, the minimum diameter transmission/collector line shall be 12 inches or two sizes above the minimum standard specification. If the Planning Board, upon consideration of the Director's recommendation, approves such plans and specifications, the developer shall submit the name of a qualified contractor to do the work, together with a breakdown of items, quantities and unit prices for the project. After investigating the qualifications of the proposed contractor and reviewing the breakdown submitted, the Director shall make the final determination whether to allow the contractor to proceed or to request that another contractor be submitted for approval.
C. 
The construction and laying out of all sewer lines and other wastewater works pursuant to this section shall be subject to the inspection of the Director. If at any time the Director shall determine that the construction and laying out of such sewer lines and other wastewater works is not being performed in accordance with the plans and specifications as approved, he shall forthwith notify the developer to this effect in writing, who shall then order the suspension of all further work by the contractor until such corrections are made as will produce complete compliance with the plans and specifications.
D. 
All wastewater works constructed pursuant to the provisions of the preceding section shall become the property of the Town. After such wastewater works have been connected with the public sewer, all the normal costs of operating and maintaining them shall be borne by the Town. However, the Town may backcharge the contractor and/or the developer for any abnormal conditions for a period of six months after acceptance.
E. 
Should a developer's plan include necessary pump stations, as approved by the Director, the Town will be in a position of incurring additional maintenance and replacement costs. Prior to construction approval from the Director, the developer shall post a maintenance/replacement fee of $25,000 per pump station with the Town.
The following design standards for sanitary sewers are considered acceptable:
A. 
At the juncture between a sewer and one of larger diameter, the inverts of the sewers shall be designed so that the peak flow lines match.
B. 
Velocities greater than 12 feet per second (3.7 mps) or less than two feet per second (0.61 mps) when flowing will be unacceptable, except near ends of laterals.
C. 
Installing a smaller sewer downstream from a larger sewer in general will be considered unacceptable.
D. 
Sewers of a diameter from eight inches (20.3 cm) through 21 inches (53.3 cm) shall be designed so that they are flowing at a depth no greater than 0.6 times the diameter of the sewer at peak flow rates.
E. 
Sewers of a diameter larger than 21 inches (53.3 cm) shall be designed so that they are flowing at a depth no greater than 0.7 times the diameter of the sewer at peak flow rates.
F. 
Sewers shall be designed using a Manning's “n” of 0.10 to 0.013 constant with depth, depending on material of the sewer.
G. 
No public sewer shall be less than eight inches (20.3 cm) diameter, and all public sewers shall be constructed in streets, easements or right-of-ways.
H. 
Manholes shall be installed at the end of each line; at all changes in grade, size, or alignment; at all intersections; and at distances not greater than 400 feet (121.4 m) or as approved by the Director.
I. 
Manholes shall be constructed of precast reinforced concrete, American Society for Testing and Materials Designation C478, latest edition; concrete masonry units, ASTM designation C139, latest edition; or as approved by the Director.
J. 
All sanitary sewers and appurtenances shall be designed and constructed in accordance with WPCF Manual of Practice No. 9, Design and Construction of Sanitary and Storm Sewers, latest revision, and TR-16; Guides for the Design of Wastewater Treatment Works, as prepared by the Technical Advisory Board of the New England Interstate Water Pollution Control Commission.
K.

(4) 
Acrylonitrile-butadiene-styrene (ABS) meeting ASTM specification D2751 with gasket-type joints.
Sewer service connections from the public sewer to the street line shall be laid at such depth and gradient and in such location as the Director may determine. No sewer service connection shall serve more than one building, except by permission of the Director. All pipe shall have compression joints. The following design standards for buildings sewers, are considered acceptable:
A. 
The pipes for building sewers from the public sewer to the property line shall be six inches (15.2 cm) in diameter, but larger sizes may be required by the Director. The building sewer from the property line to the building drain shall be a minimum of four inches (10.2 cm) in diameter, but larger sizes may be required by the Director. All such pipes shall conform to § 207-37K. Building sewer pipes shall be laid with a minimum gradient of at least 1/4 inch per foot (2.1 cm/m), without 90° bends. The pipes shall be laid accurately to straight lines and gradients, except that junctions with public sewers shall be made at an angle, by installing a six-inch (15.2 cm) by six-inch (15.2 cm) wye or tee, such that flow from the building sewer shall be not opposite in direction to the flow in the public sewer. Where depth of the public sewer is such that a chimney is required, such chimney shall be installed per Town specifications. Special means for flushing and cleaning (cleanouts) in accordance with the particular requirements of the Director shall be provided in the building sewer at seventy-five-foot increments, at all significant changes in direction and as otherwise required by the Director. The connection of the building sewer into the public sewer shall be made at the wye or tee branch, if such branch is available at a suitable location. If no branch is available, a connection must be made by tapping the existing sewer by an approved method, then inserting an approved wye or tee saddle, all encased in concrete. Approval of tapping method and saddle shall be made by the Director.
B. 
No service pipes for other utilities, such as water, gas and the like, whether Town-owned or privately owned, shall be laid in the same trench with a building sewer, except by written approval of the Director.
Whenever possible, the building sewer for new buildings 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 means of a sewage pump, and discharged to the building sewer, upon approval of the Director. However, the Town shall have no responsibility for the operation and maintenance of such equipment.
No person shall make or keep a connection of roof downspouts, exterior 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 sewer.
The connection of the building sewer into the public sewer shall conform to the requirements of the building and plumbing code or other applicable rules and regulations of the Town and/or the procedures set forth in appropriate specifications of the ASTM and WPCF Manual of Practice No. 9, latest edition. All such connections shall be made gastight and watertight. Any deviation from the prescribed procedures and materials must be approved by the Director before installation.
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.[1]
