A.    A sanitary sewage disposal system shall be designed and constructed by the subdivider to provide adequate sewage service for all lots in the subdivision. Except for administrative or agricultural subdivisions, sewage treatment shall be provided by a municipally owned or controlled sewage treatment plant.

    B.    Reserved.

    C.    Improvement plans for a permanent sewage system shall be provided showing pipe sizes, gradients, type of pipe, invert and finished grade elevations, location and type of manholes, service line locations, and the location, type and size of all lift or pumping stations. The following standards shall apply to all sewer systems:

    1.    At least eight-inch sewer lines will be installed whenever more than one single-family residence is to be served. If force mains are to be used, the line shall be sized to provide adequate service to the proposed development.

    2.    At least six-inch service connections from the sewer line to the property line of each lot will be installed with the location marked.

    3.    Manholes or inspection holes, will be provided at all interceptor and lateral junctions, at the end of each line, and at all changes in direction, grade and size.

    D.    For properties unable to be served by public sewer collection systems:

    1.    Each lot must be served by an individual subsurface disposal system of sufficient size to accommodate the wastewater generated by the uses permitted on the property. The permeability ratings contained in the Soil Survey of Bartholomew County shall be used as a basis for determining land suitability for subsurface disposal systems, unless an on-site soil evaluation by a qualified soil scientist shows that other soil types are found on the property. The department or commission may request that any such evaluation be reviewed by the Soil Conservation Service. (Ord. 99-24 § 3 (part), 1999: Ord. 94-5 § 3 (part), 1994; prior code § 28-49)
