(A) The subdivider shall construct a complete sanitary sewer system which shall adequately serve all lots and which shall be properly connected to the public sanitary sewer system. Where a public sanitary sewer system is not accessible within 500 feet of the subdivision, the subdivider shall install alternate sanitary sewer facilities, which shall be approved by the Plan Commission and the County Health Officer. In any case, sanitary sewer facilities shall be installed in accordance with plans and specifications as approved by the state’s Department of Environmental Management.
(B) No connection draining stormwater runoff, including roof drains or basement sumps shall be made to a sanitary sewer.
(C) Design of sanitary sewer systems shall be in accordance with the construction standards of the town.
(D) The use of lift stations in the design of the sanitary sewer system shall be avoided wherever possible and practical. The inclusion of lift stations shall be subject to specific approval of the Town Engineer and the state’s Department of Environmental Management.
(E) Whenever a new subdivision will create flows that will exceed the capacity of the existing sewer collection system, the developer shall be required to make those improvements necessary in the downstream portions of the system to ensure adequate capacity to handle the proposed flow.
(F) Selected design criteria.
(1) 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. Unless specifically approved otherwise, sanitary sewer manholes shall not be located within drainage ditches, swales, or other defined drainage areas.
(2) Manholes. Manholes shall be installed at the end of each line, at any change in direction, and at distances not greater than 450 feet on straight sections of sanitary sewer lines. The use of cleanouts other than as required on service laterals shall not be allowed.
(3) Cover. Unless specifically approved otherwise due to topography or limitations caused by connection to existing sewers, the minimum cover on sanitary sewers shall be six feet in streets and three feet in all other areas.
(4) Laterals. Service laterals shall be provided to each lot proposed by the subdivider. Connections other than Y-connections shall be installed on the mainline sewer for the purpose of connecting service laterals. The minimum size of service laterals shall be six inches in diameter.
(5) Government approval. Any lift stations, grinder pumps, and the like that are to be dedicated to and eventually accepted by the town for ownership and maintenance shall come from equipment manufacturers approved by the town and the state’s Department of Environmental Management. All other equipment proposed to be used by the developer must be approved by the town in advance.
