Sanitary facilities shall be designed and constructed by the developer as required for the district in which the proposed subdivision is located for the proper disposal of wastes for each lot, as follows:
(a) Public System. Where the proposed subdivision is located in a district requiring sanitary sewers and such a sewer outlet is accessible within one thousand (1,000) feet, a public sanitary sewer system shall be provided and connected thereto, and a house connection shall be provided for each lot.
(b) Independent System. Where a subdivision of forty (40) or more units is located in a district requiring sanitary sewers but such a sewer outlet is not within one thousand (1,000) feet, the Commission may permit the design and construction of an independent sanitary system including a primary and secondary treatment plant and a house connection for each lot, provided that such a system is designed and the plant located so that it can be integrated into the Sewer Plans of the City and the temporary treatment plant abandoned when public trunk sewers are installed.
Where a number of small subdivisions are proposed for adjacent tracts or in close proximity, and where combined developments will aggregate at least forty (40) units or at least forty (40) acres, the City may construct an independent sanitary system and assess the costs to the benefitted owners.
An independent treatment plant shall be located on a site of sufficient area to serve the entire tributary area and be located at least three hundred (300) feet, or as may be further required, from any dwelling.
(c) Septic Tanks. Where a subdivision of less than forty (40) units and less than forty (40) acres is located in a district permitting septic tanks, or located in a district planned for a sanitary sewer system but an outlet is not accessible within one thousand (1,000) feet, individual septic tanks may be installed on lots of not less than one acre in area or as required by the zoning code if soil percolation tests by the City Engineer have indicated a reasonable useful life for such disposal method.
In addition, the Commission may require the construction of a system of sanitary sewers and laterals for house connections, all of which are to be capped, if the construction of a trunk sewer is planned or programmed for the area.
(d) Design Standards. The sanitary system shall be designed and constructed in accord with the standards and master plans of the City, or the Ashtabula County Sanitary Engineer where he may have jurisdiction. Septic tanks shall be designed and constructed in accord with regulations of the Conneaut or Ashtabula County Board of Health, whichever has jurisdiction.
