Description

Horizontal septic tanks provide settlement and some biological treatment to raw domestic sewage (wastewater), however, the domestic wastewater is not fully treated and must receive additional treatment before discharge to the water environment – the most common method being to spread the waste to land via an underground drainage field.

As an optional extra, Marsh can supply horizontal septic tanks with a unique Polylok filter that is designed to further reduce suspended solids by up to 40% – prolonging system efficiency and drainage field life.

Horizontal septic tanks up to 20,000 litres are also tested and certified to EN12566-1.
