A. Acceptable types of systems. The DEVELOPER shall provide the most effective type of sanitary sewage disposal consistent with the natural features, location and proposed DEVELOPMENT SITE. The following types of sanitary sewage disposal are listed in order of preference:
1. Connection to a public sanitary sewage disposal and treatment system.
2. Provision by the DEVELOPER for a community sanitary sewage disposal system capable of being tied into a public system in accordance with the requirements of the Department of Environmental Protection and acceptable to the township.
3. Capped sewers with temporary, approved on-lot facilities.
4. On-lot sewage disposal systems consisting of septic tanks with tile fields or other approved system.
B. Connection to a public sewer system. Connection to a public sanitary system shall be required where such a system can feasibly be provided to adequately fulfill the sewage disposal needs of the proposed SUBDIVISION or LAND DEVELOPMENT tract.
C. Installation of capped sewers. Where a public sanitary sewer system is not yet accessible to the site but has been scheduled and a preliminary design has been prepared for such an extension to the SUBDIVISION within a ten-year period, the DEVELOPER shall install sewer lines, including lateral connections as may be necessary to provide adequate service to each lot when connection with the sewer system is made. The sewer lines shall be suitably capped at the STREET
right-of-way line. When capped sewers are provided, on-site disposal facilities shall also be provided. Design of the capped system shall be in accordance with the standards of the Pennsylvania Department of Environmental Protection and subject to the approval of the BOARD of Supervisors.
D. Provision of community sewerage system.
1. Where a public sanitary sewer system cannot feasibly be provided to the proposed SUBDIVISION or LAND DEVELOPMENT tract or is not planned for extension to the proposed SUBDIVISION or LAND DEVELOPMENT tract, the BOARD, upon recommendation by the Township Engineer, may require the submission of a community sewerage system feasibility report.
2. When a sewage feasibility report is required, it must be prepared by a registered engineer and submitted to Marshall Township, the county and the Pennsylvania Department of Environmental Protection.
E. Provision of on-lot sewage disposal. In SUBDIVISIONS or LAND DEVELOPMENTS where neither connection to a public sewerage system nor a community sanitary sewer system is required, sewage disposal consisting of septic tanks and absorption fields shall be provided on individual lots. The physical features of the tract on which on-lot disposal is provided shall meet the criteria established by the Pennsylvania Department of Environmental Protection, the Allegheny County Health Department and/or Marshall Township for on-lot sewage disposal systems.
