The Marsh Ultra Polylok L 6 Person Sewage Treatment Plant is a domestic treatment plant that complies with BS EN 12566-3. It serves up to 6 people, which suits a typical three or four bedroom house.
How the Ultra Polylok L 6 Person Sewage Treatment Plant works
First, solids settle and break down in the primary chamber. Next, the liquid moves into an aeration chamber, where air and mobile media help bacteria remove the pollutants. Finally, the treated water settles once more before it leaves the plant, so maintenance stays simple and running costs stay low.

Before adding the Ultra Polylok L 6 Person Sewage Treatment Plant to your basket, choose a gravity or pumped outlet and a deeper inlet if your drain arrives lower than standard. The price updates as you pick each option.
Servicing and permits
Like all treatment plants, this unit needs desludging from time to time, and the compressor should be serviced regularly. For this reason, we recommend a service contract with a local engineer. In addition, please check with the Environment Agency, SEPA or Natural Resources Wales whether your discharge needs a permit or falls under the General Binding Rules.
