Title 18 Water and Sewers
Chapter 6 Sewer Use Regulations
18-605 : Building sewers and connections.
-
General. No unauthorized person shall uncover, make any connections with or opening into, use, alter, or disturb any POTW sanitary sewer or appurtenance thereof without first obtaining a written permit from the control authority.
All cost and expense incidental to the installation and connection of the building sewer to the POTW sanitary sewer shall be borne by the user. The user shall indemnify the town from any loss or damage that may directly or indirectly be occasioned by the installation of the building sewer.
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 building 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.
Old building sewers may be used in connection with new buildings only when they are found, on examination and testing by the control authority, meeting all requirements of this chapter. All others must be sealed to the specifications of the control authority.
- Building sewer construction. Building sewers shall conform to the following requirements:
- The minimum size of a building sewer shall be six (6) inches.
- The minimum depth of a building sewer shall be eighteen (18) inches.
- Six (6) inch building sewers shall be laid on a grade equal to or greater than 1/8-inch per foot. Larger building sewers shall be laid on a grade that will produce a velocity when flowing full of at least 2.0 feet per second.
- Slope and alignment of all building sewers shall be neat and regular.
- Building sewers shall be constructed only of (1) cast iron soil pipe or ductile iron pipe with compression joints or (2) polyvinyl chloride pipe with rubber compression joints. Under no circumstances will cement mortar joints be acceptable.
- Cleanouts shall be located on building sewers as follows: one located five (5) feet outside of the building, one at the tap onto the POTW sanitary sewer and one at each change of direction of the building sewer which is greater than 45 degrees. Additional cleanouts shall be placed not more than seventy-five (75) feet apart in horizontal building sewers of six (6) inch nominal diameter and not more than one hundred (100) feet apart for larger pipes. Cleanouts shall be extended to or above the finished grade level directly above the place where the cleanout is installed. A "Y" (wye) and 1/8 bend shall be used for the cleanout base. Cleanouts shall not be smaller than four (4) inches on a six (6) inch pipe.
- Connections of building sewers to POTW sanitary sewer shall be made at the appropriate existing wye or tee branch using compression type couplings or collar type rubber joint with corrosion resisting or stainless steel bands. Where existing wye or tee branches are not available, connections of building services shall be made by either removing a length of pipe and replacing it with a wye or tee fitting or cutting a clean opening in the existing public sewer and installing a tee-saddle or tee-insert of a type approved by the control authority. All such connections shall be made gastight and watertight.
- The building sewer may be brought into the building below the basement floor when gravity flow from the building to the POTW sanitary sewer is at a grade of 1/8-inch per foot or more, if possible. In cases where basement or floor levels are lower than the ground elevation at the point of connection to the sewer, adequate precautions by installation of check valves or other backflow prevention devices to protect against flooding shall be provided by the user. In all buildings in which any building drain is too low to permit gravity flow to the POTW sanitary sewer, wastewater carried by such building drain shall be lifted by an approved means and discharged to the building sewer at the expense of the owner.
- The methods to be used in excavating, placing of pipe, jointing, testing, backfilling the trench, or other activities in the construction of a building sewer which have not been described above shall conform to the requirements of the building and plumbing code or other applicable rules and regulations of the town or to the procedures set forth in appropriate specifications of the ASTM and Water Pollution Control Federal Manual of Practice No. 9. Any deviation from the prescribed procedures and materials must be approved by the Control Authority before installation.
- An installed building sewer shall be gastight and watertight.
- 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 control authority.
- No person shall make connection of roof downspouts, exterior foundation drains, area drains, basement 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 POTW sanitary sewer.
- Inspection of connections.
- The connection to the POTW sanitary sewer and all building sewers from the building to the POTW sanitary sewer shall be inspected by the control authority before the underground portion is covered.
- The applicant for discharge shall notify the control authority when the building sewer is ready for inspection and connection to the POTW sanitary sewer. The connection shall be made under the supervision of the control authority.
- Maintenance of building sewers. Each user shall be entirely responsible for the maintenance of the building sewer located on private property to insure that the building sewer is watertight. This maintenance will include repair or replacement of the building sewer as deemed necessary by the control authority to meet specifications of the town. If, upon smoke testing or visual inspection by the control authority, roof downspout connections, exterior foundation drains, area drains, basement drains, building sewer leaks or other sources of rainwater, surface runoff or groundwater entry into the POTW sewer system are identified on building sewers on private property, the superintendent may take any of the following actions.
- Notify the user in writing of the nature of the problem(s) identified on the user's building sewer and the specific steps required to bring the building sewer within the requirements of this chapter. All steps necessary to comply with this chapter must be complete within 60 days from the date of the written notice and entirely at the expense of the user.
- Notify the user in writing of the nature of the problem(s) identified on the user's building sewer and inform the user that the town will provide all labor, equipment and materials necessary to make the repairs required to bring the building sewer within the requirements of this chapter. The work on private property will be performed at the town's convenience and the cost of all materials used will be charged to the user. The town will be responsible for bringing any excavations back to original grade, replacing topsoil and hand raking all disturbed areas; however, the user shall be responsible for final landscaping, including but not limited to seeding, fertilizing, watering, mulching, sodding and replacing any shrubbery or trees displaced or damaged by the town during the execution of the work.
