Septic tanks partially treat effluent and are the simplest and most economic way for sewage disposal where mains drainage is not available, We Stock most models for quick deliveries. We can supply both spherical (2800ltr - 6000ltr) and cylindrical (2800ltr - 54000ltr) septic tanks for all your needs.
Septic tanks consist of either 2 or 3 chamber system which holds sewage solids long enough to allow the solids to form into sludge at the bottom of the tank. It then partially breaks down through anaerobic digestion and the remaining liquid passes through the outlet pipe to a soakaway.
The cylindrical septic tank allows reduced depth excavation in comparison with the spherical septic tank, therefore reducing excavation costs. The cylindrical septic tanks are also used where there is a high water table or difficult ground conditions.
