Septic tanks are a traditional solution for domestic sewage disposal, they are ideal for situations where access to mains sewer is not possible or practical.

Formed from a single chamber, the sewage from a domestic property or small business premise is collected and retained in the tank. Time allows it to be anaerobically digested, breaking the solids down into sludge. The excess effluent liquid then flows from the tank, via the outlet, and into a suitable drainage field system.

These Kingspan Clearwater Alpha septic tanks are made from Glass Reinforced Plastic (GRP), strong but light, watertight and also chemically resistant. These septic tanks are traditionally shaped like an onion, with the most popular being manufactured by Clearwater and Klargester. They are performance tested in accordance with EN-12566 (Part 1) to make sure that they meet installation requirements and that the standards of discharge are as they should be. 

When planning your installation, make sure that these systems are installed at least 7 metres away from any sort of dwelling and that they are at least 10 metres away from any watercourse. 

Please note: this tank comes complete with A15/pedestrian cover and frame. Max inhabitants is indicative usage of 150 litres/per person/per day.
