1181.05 SANITARY WASTE DISPOSAL.
   (a)    Public System. When the proposed subdivision is located within five hundred feet of an adequate sanitary sewer line, a connection to the line shall be provided for each lot
by the developer.
   (b)    Independent System.
      (1)    When lots are less than one acre and a sanitary sewer is not available, except as provided in subsection (d)(2) hereof, an adequate sanitary treatment plant and the necessary sanitary sewer lines accessible to each lot shall be provided by the developer. The system, where practicable, is to be designed so it can be integrated into the master plan of sanitary sewers when the public sewers are installed.
      (2)    Where a number of subdivisions are proposed to be on adjacent tracts and/or sufficient buildable property is in close proximity to each other, the legislative authority may cause to have constructed a sanitary treatment plant and the necessary lines, except laterals, to serve the plats, and assess the costs to the benefitted owners.
   (c)    Sanitary Manhole. The minimum elevation at the top of any sanitary manhole casting shall be not less than one foot higher than the estimated twenty-five year high water level.
   (d)    Septic Tanks.
      (1)    Septic tanks may be used for lots of one acre or more in area if soil percolation tests, as prescribed by the appropriate Board of Health, have indicated a reasonably useful life for such disposal methods. Other methods of disposal may be approved by the appropriate Board of Health.
      (2)    Subject to approval of the appropriate Board of Health, septic tanks may be used on lots with less than one acre when the plat is in an area that can expect trunk sewers to be extended to it within a two year period as determined by the Director of Public Service, but sanitary lateral sewers serving each lot, properly installed and blocked off shall be provided. (Ord. 25-70. Passed 5-4-70.)
