(A) General requirements.
(1) Sanitary sewers shall be located within street or alley rights-of-way or in perpetual, unobstructed easements. When sanitary sewer facilities are located in easements, access easements to all manholes shall be provided. Whenever sewer lines in private easements cross a public street or alley right-of-way, a manhole shall be provided in such public right-of-way.
(2) A minimum horizontal distance of ten feet shall be maintained between parallel water lines and sewer lines. Perpendicular or angled crossings of water and sewer lines shall generally be at a spacing of not less than 18 inches. If the minimum spacing cannot be met, special design details (such as encasement in sleeves) may be approved by the town’s Engineer and the Superintendent of the Zionsville Wastewater Treatment Plant for the town.
(3) Sanitary sewer capacity allocations shall be approved by the Town Council.
(4) All sanitary sewer easements which are to be dedicated to the town on the secondary plat shall use the following language: “All sanitary sewer easements shown on this plat are hereby dedicated to the Town of Zionsville, Indiana.”
(5) The subdivider shall provide sanitary sewer facilities in accordance with the town’s construction standards, and the Great Lakes-Upper Mississippi River Board of State Public Health and Environmental Managers, Recommended Standards for Wastewater Facilities. The design shall be approved by the appropriate town, local, state and federal agencies where required by those agencies.
(B) Individual disposal system requirements.
(1) In the O-1 Zoning District, if a public or semi-public sewer system is not available, the Plan Commission, in its discretion, may approve the use of individual disposal systems for each lot.
(2) An individual disposal system shall be approved by the county’s Health Department prior to the issuance of an improvement location permit for any building or structure on a lot.
(C) Connection to town sanitary sewer utility.
(1) Sanitary sewer facilities, whenever practical, shall connect to a public sanitary sewer facility provided by the town. In those instances where the Plan Commission determines that connection to town sewer facilities would pose an unusual or unnecessary hardship at the time of development, the Plan Commission may make a recommendation to the Town Council to approve a connection to another public or semi-public sewer utility; provided, however, that, the sewer facilities are installed to the town’s construction standards or alternative standards approved by the town’s Engineer, and provision is made in the design and layout of the sewer facilities for connection to the town sewer facilities at such time as the town extends public sewer facilities to the subdivision.
(2) All semi-public sanitary sewer systems shall be approved by the county’s Health Department or the state’s Board of Health prior to the issuance of an improvement location permit for any building or structure on a lot.
