The Marsh Ensign Ultra 16 is an upgrade on the Ensign Standard sewage treatment plant which also complies with BS EN 12566-3. With a population equivalent of 16, this treatment plant is suitable for 2 x 4 bed  and 1 x 3 bed houses or 25 people in a workplace environment (without a canteen).

The Ensign 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.

Please note this plant is available as an option with of an internal or external air blower.
