(A) General requirements. The subdivider shall install sanitary sewer facilities in a manner prescribed by the city construction standards and specifications. All plans shall be designed in accordance with the rules, regulations, and standards of the City Engineer, Health Department, and other appropriate state and federal agencies. In addition, the design shall meet or exceed the minimum standards described in the latest edition of Recommended Standards for Sewage Works as published by the Health Education Service, Albany, New York, and plans shall be approved by all state and federal agencies where required by those agencies.
(B) Sanitary sewerage system requirements. Where provided, sanitary sewerage facilities shall connect with public sanitary sewerage systems, and shall be installed to serve each lot to grades and sizes required by approving officials and agencies. Sanitary sewerage facilities (including the installation of laterals in the right-of-way) shall be subject to the specifications, rules, regulations, and guidelines of the Health Officer, participating jurisdiction, and appropriate state agency.
(C) Individual disposal system requirements. If public sewer facilities are not available and individual disposal systems are proposed, minimum lot areas shall conform to the requirements of the zoning ordinance and any ordinance of any participating jurisdiction (where applicable) establishing lot areas for individual sewerage disposal systems.
(D) Selected design criteria.
(1) Alignment. All sewers shall be laid with a straight alignment between manholes, unless otherwise directed or approved by the City Engineer.
(2) Manhole location. Manholes shall be installed at the end of each line, and at distances not greater than 400 feet for sewers 18 inches in diameter and larger.
(3) Manholes. The difference in elevation between any incoming sewer and the manhole invert shall not exceed 12 inches where required to match crowns. The use of drop manholes requires approval by the City Engineer. The minimum inside diameter of the manholes shall conform to those specified by the City Engineer. Inside drop manholes will require special consideration; however, in no case shall the minimum clear distance be less than that indicated herein. The relationships between intersection sewer lines shall meet the standards required by the City Engineer. (See division (D)(1) above.)
(4) Sewerage locations. Sanitary sewers shall be located within street or alley rights-of-way unless topography dictates otherwise. When located in easements on private property, access shall be provided to all manholes. Where sewer lines in private easements cross public street or alley rights-of-way, a manhole shall be provided in such rights-of-way where possible. Imposed loading shall be considered at all manhole locations. Not less than six feet of cover shall be provided over the top of pipe in street and alley rights-of-way or three feet in all other areas.
(5) Cleanouts. Cleanouts will not be permitted.
(6) Water supply interconnections. There shall be no physical connection between a public or private potable water supply system and a sewer which will permit the passage of any sewage or polluted water into the potable water system. Sewers shall be kept removed from water supply wells or other water supply sources and structures.
(7) Relation of sewers to water mains. A minimum horizontal distance of ten feet shall be maintained between parallel water and sewer lines. At points where sewers cross water mains, the sewer shall be constructed of cast iron pipe or encased in concrete for a distance of ten feet in each direction from the crossing, measured perpendicular to the water line. This will not be required when the water line is at least two feet above the sewer line.
