 Klargester Alpha Septic Tank Installation Guidelines

 Klargester Alpha 4600L Drawing

Septic Tanks

A septic tank consists of a two or three chamber system that retains sewage from a property for sufficient time to allow the solids to form into sludge at the base of the tank, where it is 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. Spherical septic tanks are manufactured as standard from 2,800 to 4,600 litres net working capacity. Septic Tanks have a 1.0m standard invert depth.

All Klargester tanks are designed to meet both the installation requirements and the standards of discharge specified by EN 12566 Part 1.
