Marsh Industries sewage treatment plants have been tested for pH levels, a test that is included in BS EN 12566-3 the new standard for sewage treatment plants. A version of the UNI ENsign is also available for use in areas with a particularly high water table including a built-in effluent pump if required. With a 25 year internal and external structual warranty, these units will give you a long term solution for treatment of your sewage. The Marsh ENsign also benefits from very few moving components plus there is very little servicing to be carried out. This has the significant benefit of helping to reduce long term running costs of sewage treatment plants.
The Marsh ENsign is also on the Enviroment Agency's certified products list. This means the plant can qualify to register for exemption from a permit to discharge. This speeds up the process of having to wait, sometimes up to 4 months, for Environment Agency Approval - the E.A. aim to give an exemption certificate within 15 working days.
In addition to new / replacement installations, Bates Environmental Ltd offer full servicing and replacement parts, such as compressors, for Marsh Industries sewage treatment plants.
