GRP Septic Tanks
A grp septic tank partially treats effluent and is the simplest and most economic solution for sewage disposal where mains drainage is not possible.
It consists of a 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.
Captrad can supply both fiberglass spherical (2800ltr - 6000ltr) and cylindrical (2800ltr - 54000ltr) GRP Septic Tanks. GRP tanks can used whether it's a domestic dwelling, caravan site or even a leisure park.
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.
