The structural integrity of the tank must be verified. The septic tank shall two-compartment tank, steel with bitumastic undisturbed soil. If depth of 4 feet or less, an overlying layer of 2 polystyrene rigid board be a UPC-approved constructed of 12 gauge coating and set level on the tank is buried at a it must be insulated with inch burial type insulation. (907) ~79-5553 2.3 2.4 2.5 2.6 2.7 The septic tank shall the house foundation, the absorption area. be a minimum of 5 feet from and a minimum of 5 feet from The septic tank and bed shall be a minimum of 100 feet from any private well or body of water, 150 feet from Class "C" wells, and 200 feet from Class "A" or "B" wells, unless otherwise specified.

Piping shall be fitted with a mechanical watertight calder coupling on the outlet and inlet of the septic tank. Piping shall be 4 inch solid PVC ASTM D-3034 or cast iron, sloped a minimum of 1/4 inch per lineal foot on the inlet side and 1/8 inch per foot on the outlet side. If the piping is buried at a depth of 4 feet or less, it must be insulated with an overlying layer of 2 inch burial type polystyrene rigid board insulation. Cleanouts shall be installed as designated and capped with air-tight rain caps (Jim Caps or equivalent), and extend a minimum of 1 foot above ground level. If a lift station is required it shall be a combination lift station septic tank per Anchorage Tank and Welding, Inc. using an 0RENC0 lift station design.
