The Clearwater Alpha septic tank is manufactured by Kingspan Environmental and is made from Glass Reinforced Plastic (GRP). 

A septic tank consists of one chamber which retains sewage from a property for sufficient time to allow the solids to form into sludge at the base of the tank, where is it partially broken down through anaerobic digestion. The remaining liquid in the tank then overflows from the tank by means of an outlet pipe to a drainage field/soakaway.

Serves up to twelve people in a domestic application.
