(A) General. The applicant shall install sanitary sewer facilities in a manner prescribed by the city or county construction standards as approved by the City Engineer. All plans shall be designed and sewer facilities (including laterals in the right-of-way) installed, subject to the specifications, rules, regulations, and guidelines of the City Engineer and appropriate health and other officials. Where conditions exist that would require a sewer size larger than what is normally required for a particular size subdivision, the city shall bear the additional cost between what would normally be required for the subdivision and the oversized facility.
(B) High density residential and nonresidential districts. Sanitary sewer facilities shall connect with public sanitary sewer systems. Sewers shall be installed to serve each lot and to grades and sizes required by appropriate local officials and agencies. No individual disposal system or treatment plants (private or group disposal systems) shall be permitted.
(C) Low and medium density residential districts. Sanitary sewer systems shall be constructed as follows.
(1) Where a public sanitary sewer system is reasonably accessible (as determined by the Plan Commission), the applicant shall connect with same and provide sewers to each lot in the subdivision.
(2) Where public sanitary sewer systems are not reasonably accessible but will become available within a reasonable time not to exceed 15 years, the applicant may choose to install one of the following alternatives.
(a) Central sewerage system with the maintenance cost to be assessed against each property benefited. Where plans for future public sanitary sewer systems exist, the applicant shall install the sewer lines, laterals, and mains in conformance with the plans and ready for connection to the future sewer mains.
(b) Individual sewage disposal systems, provided the applicant shall install sanitary sewer lines, laterals, and mains to a point in the subdivision boundary where a future connection with the public sewer main shall be made. Sewer lines shall be laid from the individual dwellings to the street line, and a connection shall be available in each dwelling to connect from the individual disposal system to the sewer system when the public sewers become available. The sewer systems shall be appropriately capped until ready for use.
(3) Where sanitary sewer systems are not reasonably accessible and will not become available within an estimated 15-year period, the applicant may install sewerage systems as follows.
(a) Medium Density Residential Districts shall have a central sewerage system. No individual disposal system will be permitted. The Commission may, however, where plans exist for a public sewer system to be built beyond a period of 15 years, require that the applicant install all sewer lines, laterals, and mains in conformance with the plans and ready for connection to the public sewer mains.
(b) Low Density Residential Districts may have individual sewage disposal systems or a central sewerage system can be used.
(D) Mandatory connections to public sewers. If a public sanitary sewer is accessible and a sanitary sewer is placed in a street or alley abutting upon a property, the owner thereof shall be required to connect to the sewer for the purpose of disposing of waste. It shall be unlawful for any owner or occupant to maintain upon the property an individual sewage disposal system.
(E) Individual disposal system requirements. Minimum lot areas shall conform to the requirements of the zoning code, and test holes and percolation tests shall be made as directed by the City Engineer in conformance with Health Department regulations. There shall be at least one percolation test for every three lots, and the test holes shall be distributed throughout the subdivision and not concentrated in any one location. Distribution should be approved by the City Engineer. Should the test indicate poor percolation in the subdivision, percolation tests may be required on each lot by the Commission.
