There are three main Septic Systems used in the Shoalhaven area:
1. A.W.T.S or Supertreat System
2. Pump Out System
The pump out system is a two tank system where the household grey and blackwater flows into a septic tank. It is naturally churned over using a bafflewall and the liquids then overflow into the pump out tank. This tank will require a pump out from time to time, usually around 8 weeks for a fully occupied home.
3. Site Disposal System
The site disposal system is a one tank system attached to absorption trenches. The grey and black water runs into the septic tank through the bafflewall and the overflow liquid then goes into an absorption trench where it is dissolved into the ground.
Bennett’s Concrete not only install septic tanks and systems but also can upgrade your existing absorption trenches to satisfy Council’s regulations. We are also able to supply and install new concrete septic tank lids in a range of sizes to replace those old, broken and dangerous lids.
Super-Treat is a wastewater treatment system which employs the principle of “aeration” for the reduction of septic tank effluent to an environmentally acceptable quality. Super-Treat “domestic” systems are package plants which typically treat households of up to 10 persons living in permanent residence. Super-Treat “commercial” systems are purpose designed for each particular application, of any size up to 10 persons.
In unsewered locations, the Super-Treat is a “go anywhere” system which can be installed:
