The Marsh Ensign Ultra 6 Person Sewage Treatment Plant is the premium Ensign plant, built for the quietest running and the cleanest final effluent. It serves up to 6 people, which suits a typical three or four bedroom house.
What makes the Ensign Ultra 6 Person Sewage Treatment Plant different
The Ultra adds a near-silent advanced compressor with a low-pressure alarm, an RCD protected electrical connection and a Polylok tertiary filter. Together, these give better treatment and early warning if the air supply drops.
Key features
- Near-silent advanced compressor with alarm
- RCD protected electrical connection
- Polylok tertiary filter on the outlet
- Tested to BS EN 12566-3
- No moving parts inside the tank
Options
Before adding the Ensign Ultra 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.
