Pump Tanks are designed to be utilized where a normal gravity system will not work and in conjunction with a septic tank and effluent pump.  Shoaf Precast manufactures watertight mid-seam pump tanks from 1,000 gallon up to 20,000 gallon for traffic rated applications.  All pump tanks can be fitted with concrete risers or cast in plastic risers (EZset or Orenco).  Orenco adapters are used for AdvanTex Pretreatment Systems.
