A separate and independent building sewer shall be provided for every building on an improved property, except that where one building stands at the rear of another and no private or public 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 then be extended to the rear building and the whole considered as one building sewer. This modification shall require the approval of the City, in writing.
Old building sewers may be used in connection with new buildings only when they are found, on examination and test by the City, to meet all requirements of this chapter.
The size, slope, alignment, materials of construction of a building sewer and the methods to be used in excavating, placing of the pipe, jointing, testing and backfilling the trench shall all conform to the requirements of the Building and Plumbing Code or other applicable rules and regulations of the City.
Whenever possible, the building sewer 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, sewage carried by such building drain shall be lifted by means approved by the City of Laconia and discharged to the building sewer.
No person shall connect roof downspouts, exterior or interior foundation drains, areaway drains or other sources of surface runoff or groundwater or building floor drains to a building sewer or building drain which in turn is connected, directly or indirectly, to a public sanitary sewer. No person shall remove a cleanout cap from any drain, vent waste pipe or fixture for purposes of allowing water, surface or subsurface, by sump pump or by gravity flow, to enter into the sanitary sewage system without first having obtained written permission from the City. No person shall obstruct the free flow of air through any drain or soil pipe.
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 City.
During construction of a new public sewer, the City of Laconia will construct building sewers for existing buildings to the curb or property line. Construction of the remainder of the building sewer, including connection to the structures served, shall be the responsibility of the owner of the improved property to be connected, and such owner shall indemnify and save harmless the City of Laconia and its officers and agents, from all loss or damage that may be occasioned, directly or indirectly, as a result of construction of a building sewer on his premises or its connection to the sewer system. After the initial construction of the building sewer, the owner shall thereafter be obligated to pay all costs and expenses of operation, repair and maintenance and of reconstruction (if needed) of the building sewer beginning at the public sewer and ending at the building.
The building sewer shall be continued to the building from the stub end provided by the City of Laconia at the curb or property line and from no other point, unless authorized to do otherwise by the City. The invert of the building sewer at the point of connection to the stub provided by the City of Laconia at the curb or property line shall be at the same elevation as the stub provided by the City of Laconia. A smooth, neat joint shall be made, and the connection of a building sewer to the stub provided by the City of Laconia, shall be made secure and watertight and acceptable to the City of Laconia, with the cost of said connection to be borne by the owner.
If the owner of any improved property located within the City of Laconia and benefited, improved, served or accommodated by any public sewer or to which any public sewer is available, after 45 days' notice from the City of Laconia, in accordance with § 189-5, shall fail to connect such improved property as required, he shall be subject to the actions and penalties prescribed in RSA 252 and 147 and regulations issued pursuant thereto, or the City of Laconia may make such connection and may collect from such owner the costs and expenses thereof by such legal proceedings as may be permitted by law.
[Amended 5-27-1985 by Ord. No. 105-85.8; 5-17-1993 by Ord. No. 236-93.08; 7-9-2007 by Ord. No. 07.2007.07; 10-22-2018 by Ord. No. 2018-189-20-01]
There shall be two classes of building sewer permits: for residential, commercial and institutional services; and for service to establishments producing industrial wastes. In either case, the owner or his agent shall make application for permission to connect to a public sewer. The permit application shall be supplemented by any plans, specifications or other information considered pertinent in the judgment of the City. A permit and inspection fee of $330 shall be paid to the City at the time the application is filed for each and every connection to the public sewer for each residential, commercial and institutional unit, structure, facility or part thereof. In addition, all costs for labor and material associated with the connection effort shall be borne by said owner or owners.
For either class of building sewer permit a system development fee of $800 shall be paid to the City at the time of the application for connection to a public sewer for each and every new connection to the public sewer for each residential, commercial and institutional unit, structure, facility or part thereof. This fee is in addition to the permit and inspection fee described in § 189-20, Subsection A. A new connection is a sewer connection installed for a unit, structure, facility or part thereof where no previous sewer connection existed.
No person shall uncover, connect with, make any opening into or use, alter or disturb in any manner any public sewer or any part of the sewer system or building sewer without first obtaining a permit, in writing, from the City. Any costs for labor or material incurred by the City during the connection process shall be borne by the owner, where applicable. Said costs shall be paid to the City Treasurer to be charged to the credit of the Sanitary Sewerage Fund. Where excavation in a public street is involved, a digging permit must be obtained.
The applicant for the building sewer permit shall notify the City when the building sewer is ready for inspection and connection to the public sewer. The connection shall be made under the supervision and in the presence of the City or its representative.
The building sewer shall be tested by insertion of a test plug at the point of connection with the public sewer. Suitable provisions must be made at the point of connection for testing, which responsibility shall rest with the holder of the sewer connection permit. Details of connections and bedding of pipe, including provisions for test, shall be as specified by the State Water Supply and Pollution Control Commission. It shall then be filled with water under a head of not less than 10 feet or the equivalent air pressure. The water level at the top of the test head of water shall not drop for at least 15 minutes. If air is used, the test acceptance criteria shall be consistent with the technical paper entitled "Low Pressure Air Test for Sanitary Sewers," as published in the Journal of the Sanitary Engineering Division from the proceedings of the American Society of Civil Engineers, dated April 1964.
