(A) The subdivider shall provide the subdivision with sanitary sewage facilities in accordance with one of the three following procedures.
(1) Public collection system. In all cases where such is possible, the developer shall construct a sanitary sewer system connected to a town sewer.
(a) The plans for the system shall be approved by the respective town council if the plat of the subdivision is proposed to be located in a town, the County Highway Supervisor if the plat is proposed to be located in the unincorporated territory, and shall be designed and constructed in accordance with the Ripley County Area Sanitary Sewer Design and Construction Specifications.
(b) Service laterals shall be installed between the street main and the property line before the street is paved.
(2) Local treatment system. Where it is not possible to connect the subdivision sanitary sewer system to a town sewer, as determined by the Commission, the subdivider shall construct a local treatment system consisting of the necessary house laterals, service mains and interceptors required to conduct the subdivision’s sanitary sewage to a single treatment facility. All aspects of such system, including the treatment facility, shall be designed with the requirements of the Ripley County Area Sanitary Sewer Design and Construction Specifications and the Ripley County Area Recommended Standards for Sewage Works, and constructed by the subdivider in accordance with the requirements of the respective town council or the County Sanitarian, as the case may be.
(a) Roadway cross drains: 12 inches;
(b) Entrance culverts: 12 inches; and
(c) Perforated under-drains: eight inches.
(3) Private disposal system. Where alternatives in divisions (A)(1) and (A)(2) above are not practical, the Commission may permit the subdivider to install on each lot an individual sewage disposal system consisting of a septic tank and tile absorption field or other approved disposal system. Such systems shall be designed and constructed by the subdivider in accordance with the Recommended Standards for Individual Sewage Systems and the requirements of the County Sanitarian and the State Department of Environmental Management. In no case, however, shall private disposal systems be permitted where soil conditions exist which would prevent percolation or effluent.
(B) The plans for the installation of the sanitary sewage facilities shall be provided by the subdivider, prepared by a registered professional engineer and approved by the State Department of Environmental Management and the County Environmental Management and the County Sanitarian. Upon the completion of sanitary sewer installations, two sets of the as-builts plans for such system shall be filed with the Commission.
(C) In this section and § 155.065 of this chapter, the phrase THE SUBDIVIDER SHALL PROVIDE shall be interpreted to mean that the subdivider shall install the facility referred to, or whenever a private sewage disposal system or an individual water supply is to be provided, that the subdivider shall require, as a condition of the sale of each lot or parcel in the subdivision, that the facilities referred to in these sections shall be installed by the developer of the lots in accordance with these regulations.
