The Clearwater Sigma shallow septic tank is manufactured by Kingspan Environmental and is made from Glass Reinforced Plastic (GRP).
The shallow design of the Clearwater Sigma reduces both time and cost of installation and is suitable for installations where spherical septic tanks could not practically be installed. Typically, in areas where there is granite rock or when you’re on a high-water table.
A septic tank retains the solid waste 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 five people or three bedrooms in a domestic application.
