§ 156.137 SANITARY SEWERS AND SEPTIC SYSTEMS.
   (A)   All sanitary sewers and appurtenant facilities shall be designed and constructed in accordance with standard specifications for sanitary sewers in the Statewide Urban Design and Specifications (SUDAS) design manual and standard specifications manual. Stormwater pipe, foundation drains, sump pumps and any groundwater collection system shall be separate from the sanitary sewer and shall not discharge to the sanitary sewer.
   (B)   Where a city-approved sanitary sewer is accessible within 400 feet of the subdivision boundary, the developer shall be required to connect thereto and provide adequate sewer lines and stubs to benefit each lot. Sanitary sewer lines shall be extended to the edge of the plat when necessary for development of unplatted or platted adjoining land.
   (C)   Plans shall be prepared by an engineer and approved by the Public Works Director and the Iowa Department of Natural Resources prior to commencing construction. The developer is responsible for obtaining the Iowa Department of Natural Resources approval.
   (D)   Sewer lines and appurtenances shall be designed to meet wastewater flow requirements and standards established and adopted by the city and other regulatory agencies. In any area officially designated as flood plain zone, sanitary sewers shall be designed to withstand flooding.
   (E)   In the case sanitary sewer facilities are not accessible to the subdivision and individual private sewage disposal systems are proposed, minimum lot areas shall be one acre.
   (F)   If individual private sewage disposal systems are proposed soil percolations, tests shall be made and a report on these tests prepared by an engineer will be submitted to the Public Works Department and the County Environmental Health Director for approval. Approval must be obtained prior to installation of any private sewage disposal system. In any area officially designated as flood plain zone, private sewage disposal systems shall be prohibited.
