Septic Tank & Percolation Area
A Septic Tank System, comprising a septic tank and sub-surface percolation area, is the conventional method of on-site treatment of wastewater from the dwelling: from toilets and sinks, showers & washing machines. Sewage from the dwelling enters the septic tank where separation of solids takes place. The effluent leaves the septic tank and enters the Distribution Box (D-Box) by gravity or by pump if site elevations require it.
Tuf tite D-box
The Tuf tite D-box ensures equal distribution (by means of the adjustable weir system) to the perforated piping in stone filled trenches where final treatment and disposal of the effluent takes place.
Soil conditions must be suitable with good soakage and low water tables.
