Product Description

Suitable for One 4 bed residence & Two 3 Bed Residences - 16 People or 25 people working.

The Ensign domestic sewage treatment plant comes with lifting eyes to make unloading and installation faster and safer. We designed the Ensign plant to self-level on the base and with our unique pipe connections ensure the installation is undertaken efficiently and correctly. The six person Ensign Sewage plant is extremely strong and is only 1.95m in depth with an inlet invert of 500mm, this design reduces both the time and cost of installation, in normal ground conditions the unit only requires a pea-shingle surround. For guidance ideally the Ensign plant should be 7m from a dwelling or10m from a stream.

Package Sewage Treatment Plants (or PSTP's) are often a suitable option where groundwater in the surrounding environment is vulnerable, drainage field percolation values are restrictive, or direct discharge to watercourse or surface water sewer is the preferred discharge method. Marsh Industries Ensign range of sewage treatment plants treat final effluent to British and European Standards to allow it to be discharged back into the watercourse whilst reaching national consent standards. Our tanks can be manufactured with either a gravity or pumped outlet to meet your site requirements. At Marsh Industries we only use 100% virgin resin (no chalk fillers) in all our products. Lead times for Domestic Sewage Treatment Plants are normally only 5-7 working days. Comes with external compressor as standard.

In addition to anaerobic digestion taking place in the primary settlement chamber the Ensign: Ultra unit allows the clarified water to pass into a second 'aeration' chamber where it is treated to remove the dissolved constituents. Here aerobic bacteria supported by diffused air and mobile media, ensures full treatment is achieved before the treated effluent and 'sloughed off' bacteria flows to a final settlement chamber. The final effluent is then discharged to the drainage field or watercourse via polylok filter.

External Cabinet can be supplied free of charge, please state when ordering.
