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/properties 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.
