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.

Normally the simplest and most economical means of treating wastewater from small developments, a septic tank holds sewage and allows solids to settle into sludge at the bottom of the tank. Here it is naturally broken down by a process known as anaerobic digestion, which provides settlement and some biological treatment. The effluent is not fully treated and must receive additional treatment before discharge to the water environment – the most common method being to spread the effluent to land via an underground drainage field.
