Title 124 - NEBRASKA DEPARTMENT OF ENVIRONMENTAL QUALITY
Chapter 7 - SEPTIC TANK; CONSTRUCTION: MATERIALS USED
001 A septic tank shall be constructed of materials not subject to excessive corrosion or decay and shall be water tight. Concrete, concrete blocks, fiber reinforced plastic (FRP), high density plastic, and fiberglass are acceptable.
001.01 When precast and cast in place reinforced concrete tanks are used they shall be properly cured and of watertight construction.
001.02 All concrete interior surfaces exposed to air shall be coated with a bitumastic or similar compound beginning at an elevation 3 inches below the normal operating level to minimize corrosion.
001.03 Concrete block tanks shall be laid on a solid foundation and mortar joints shall be filled. The interior of the tank shall be surfaced with two one-fourth inch thick coats of portland cement, sand plaster, or shall be coated with a bitumastic material. Special attention shall be given to job-built tanks to insure water tightness.
001.04 The tank shall be designed to withstand soil pressures when empty and not collapse or undergo excessive deflection which would prevent the proper operation of the system, crack or distort components of the system such as the baffles, prevent proper sealing of lids over manholes and inspection ports, or reduce the volume of the system.
001.05 All septic tanks shall be permanently marked to specify the capacity in gallons, manufacturer, and the manufacturer's address. The gallon and manufacturing identification label shall be located next to the manhole towards the inlet side.
