(A) General.
(1) In all zoning districts, subdivisions with lot sizes under two acres shall be served by a central or public wastewater system.
(2) The applicant shall install a wastewater system in a manner prescribed by the State Department of Environment and Natural Resources construction standards and specifications. All plans shall be designed by a state registered professional engineer in accordance with the rules, regulations, and standards of the State Recommended Design Criteria Manual.
(3) Plans shall be approved by the appropriate agencies. All systems must be installed by a state certified installer.
(4) No person may construct, install, or operate an on-site wastewater system where a public wastewater system is available. In the event a public wastewater system becomes available in an area previously served by individual on-site wastewater systems, an amortization schedule should be determined to bring all effected properties into compliance, and the property owner shall be required to remove or reclaim the old system and hook into the public wastewater system per ARSD 74:53:01:07 and SDCL §§ 9-48 and 9-54-10.
(B) Residential and nonresidential districts. Public wastewater systems shall be required in subdivisions where lots are less than 20,000 square feet in area with individual water systems. Sewers shall be installed to serve each lot and to grades and sizes required by approving officials and agencies. No individual disposal system shall be permitted. Public wastewater systems (including the installation of laterals in the right-of-way) shall be subject to the specifications, rules, regulations, and guidelines of the State Department of Environment and Natural Resources.
