(A) General Requirements.
(1) Mandatory Connection to Public Sewer System.
(a) For newly platted developments with access to the public sewer system, stub-up sewer lines shall be located at each lot and shall be extended as illustrated in the Noblesville Standards.
(b) If a public sanitary sewer is accessible and a sanitary sewer is placed in a street or alley abutting upon property, the owner of the property shall be required to connect to the sewer for the purpose of disposing of waste, and it shall be unlawful for any such owner or occupant to maintain upon any such property an individual sewage disposal system.
(2) Individual Disposal Systems. If public sewer facilities are not available and individual disposal systems are proposed, minimum lot areas shall conform to the requirements of this chapter. Percolation tests and test holes shall be made as directed by the Planning Director and the results submitted to the Health Department. There shall be at least one percolation test for every three lots, and the test holes shall be distributed throughout the development and not concentrated in any one location. Distribution should be approved by the County Health Officer. Should the test indicate poor percolation in the development, percolation tests may be required on each lot by the Commission. The individual disposal system, including the size of the septic tanks and size of the tile fields or other secondary treatment device, shall also be approved by the Hamilton County Board of Health.
(3) Special Conditions. The Plan Commission shall have the right and discretion to require better or more stringent methods of sewage disposal when it determines that site conditions, such as poor soils, poor drainage, or otherwise, will not adequately or safely handle sewage disposal methods otherwise allowed by this chapter.
(B) Requirements for Public Sewer Systems.
(1) General. The applicant shall install sanitary sewer facilities in a manner prescribed in the Noblesville Standards. 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 Engineer of appropriate jurisdiction and appropriate Health and other officials. Sanitary sewers shall be located within the right-of-way or within a 15 foot easement in the front yard. The center of manhole covers shall be no more than 12 feet from the back of curb.
(2) SR District. In the SR District, individual disposal systems are encouraged, but public sewers may be permitted subject to the requirement for the SR District found in this chapter.
(3) Low and Medium Density Residential Districts (except for SR). Sanitary sewer systems shall be constructed as follows:
(a) Where a public sanitary sewer system is within 1,000 feet of the proposed project, as determined by the Plan Commission, the applicant shall connect with it and provide sewers to each lot in the development.
(b) Where a public sanitary sewer system is not within 1,000 feet, as determined by the Plan Commission, but will become available within a reasonable time, not to exceed 15 years, the applicant may choose to: install individual sewage disposal systems, including conventional septic systems and other types developed through new technology as approved by the Indiana State Board of Health and Hamilton County Health Department provided that sufficient area is available on the lot for two drain fields in the event that the first field would fail.
(c) 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:
1. Medium Density Residential Districts shall have a central sewerage system. Individual disposal systems will be permitted, including conventional septic systems and other types developed through new technology as approved by the Indiana State Board of Health and the Hamilton County Health Department provided that sufficient area is available on the lot for two drain fields in the event that the first field would fail.
2. Low Density Residential Districts may have individual disposal systems including conventional septic systems and other types developed through new technology as approved by the Indiana State Board of Health and Hamilton County Health Department, or a central sewerage system can be used subject to the ISBH approval.
(4) High Density Residential District. 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.
