The Marsh Ultra Polylok L12 (UPL) is a domestic sewage treatment plant which complies with BS EN 12566-3. With a population equivalent of 6, this treatment plant is suitable for dwellings with up to and including 10 bedrooms or 2 x 4 bedroom houses. 

The UPL is easy to install, reliable, and cost-effective for ongoing operation and maintenance.

The plant works initially by anaerobic digestion in the primary chamber, then aeration in the second chamber, where diffused air and mobile filter media ensure full treatment before the treated water flows to the final settlement chamber. The final effluent is then discharged to a drainage field or watercourse.
