Common sewage treatment plants on the market often exceed 2.3m high. Marsh Industries offer a range of Shallow Ensign Ultra sewage treatment plants from 4-35PE that are only 1.6m in height, meaning installation is not only possible, but easier and safer too.

*Shallow Ensign’s are often favoured when hard rock site conditions mean deeper alternatives, involving costly and time-consuming excavation.

The Marsh Ensign is widely regarded as one of the most efficient, reliable and economical sewage treatment plants on the market.

The standard Ensign has been adapted to improve reliability and the Ensign:Ultra now brings unique enhancements to further improve noise level, treatment efficiency and final effluent quality.

Tested and approved to BSEN12566-3/A1:2009 all Ensign units provide treatment well within national consent requirements. Published test results of 11.5:19.2:8.4mg/ltr (BOD:suspended solids:ammonia), with influent concentrations on test higher than those chosen by most competitor plants, effectively equates to 97% pollutant removal.

Ranging in size from 4 to 50 PE in Ultra, Standard and Shallow versions of each, and with a wide range of ancillaries, almost all site, consent and budget requirements can be met by units from the range.
