An adequate sewage disposal system must be provided and must be approved in writing by the health officer. Every effort shall be made to dispose of the sewage through a public sewerage system.

The minimum size of any septic tank to be installed under any condition shall not be less than seven hundred fifty (750) gallons working capacity. This size tank can accommodate a maximum of two (2) mobile homes. For each additional mobile home a such single tank, a minimum additional liquid capacity of one hundred seventy-five (175) gallons shall be provided. The sewage from no more than twelve (12) mobile homes shall be disposed of in any one (1) single tank installation. The size of such tank shall be a minimum of two thousand five hundred (2,500) gallons liquid capacity.

The amount of effective soil absorption area or total bottom area of overflow trenches will depend on local soil conditions and shall be determined only on the basis of the percolation rate of the soil.
