Current through Register Vol. 51, page 10, July 15, 2024
The installation requirements for septic tanks are as follows:
(1) Septic tanks shall be installed on a
  solid, level base, with access hole covers 6 inches to 12 inches below the
  finished grade. If the cover is airtight, equipped with a hasp, and kept locked
  to prevent unauthorized access, the cover may be shallower or above grade. The
  tank shall be installed at a depth that provides adequate gravity flow from the
  building or facility sewer which meets the requirements of the South Dakota
  state plumbing code, § 20:54:11:09;
(2) The tank shall be installed on
  undisturbed soil. If over-excavation occurs, it shall be backfilled with sand
  to the correct elevation and compacted. Backfilling around the tank shall be
  accomplished in a manner to prevent settlement and to prevent undue stresses on
  the tank and to the inlet and outlet pipes;
(3) When multiple tanks are used to obtain
  the required liquid volume capacity, the tanks shall be connected in series.
  The interconnecting pipes between tanks shall be at least 6 feet in length and
  unperforated. No more than 4 tanks in series are permitted to obtain the
  required liquid volume capacity. The first tank shall not be smaller than any
  of the subsequent tanks in the series;
(4) All tanks shall be located in an area
  which is accessible for the pumping of their contents. There shall be no
  constructed building or facility of any kind covering any of the
  tanks;
(5) Flotation collars shall
  be used in areas with high groundwater potential;
(6) The inlet and outlet pipes shall be made
  watertight by grouting with cement or corrosion-resistant sealants. The pipes
  shall be supported on the outside of the tank to prevent failures due to
  settling. The pipes connecting septic tanks installed in series shall be cast
  iron soil pipe of 4-inch minimum diameter; and
(7) During installation, any damage to the
  watertight coating or interior of a tank shall be repaired and tested by
  filling with water.

Current through Register Vol. 51, page 10, July 15, 2024
The minimum capacities for septic tanks serving individual or small
	 on-site systems shall be determined as follows:
(1) All septic tanks receiving wastewater
  flows of 750 gallons per day or less shall have a minimum capacity of at least
  1,000 gallons of liquid before there will be an overflow into the septic tank
  outlet. When a housing unit or units served by a septic tank contains more than
  three bedrooms, each bedroom in excess of three shall require an additional
  250-gallon increase in the capacity of the septic tank beyond the 1,000
  gallons. If a septic tank receives wastes from a garbage disposal, the overall
  capacity of the tank shall be increased by an additional 20 percent;
(2) Septic tanks serving premises other than
  housing units or receiving wastewater flows of more than 750 gallons per day
  but equal to or less than 1,500 gallons per day shall have a minimum liquid
  volume capacity to permit retention of incoming sewage at 150 percent of the
  average daily flow;
(3) Septic
  tanks receiving wastewater flows greater than 1,500 gallons per day shall have
  a minimum liquid volume capacity (V) equal to at least 1,125 gallons plus 75
  percent of the daily wastewater flow (Q), or V = 1,125 + 0.75Q; and
(4) Septic tanks serving premises where high
  amounts of oil or grease are anticipated shall be preceded by grease
  interceptors. Wastewater from garbage disposals may not be discharged to grease
  interceptors. Grease interceptors shall have a grease retention capacity of not
  less than 2 pounds for each gallon per minute of flow. The minimum size of
  grease interceptors shall be 750 gallons. Construction and installation of
  interceptors shall meet the requirements of chapter 20:54:06 of the South
  Dakota state plumbing code.
