Sewage Treatment Plants

Sewage treatment plants are increasingly replacing septic tank systems throughout rural areas of East Anglia.  Unlike septic tanks, sewage treatment plants produce a treated effluent suitable for discharge to ditches and streams and comply with Environment Agency guidelines. 

Sewage treatment plants are now produced by a large number of different manufacturers and all of these systems are designed to create an environment to develop the growth of Aerobic Micro-organisms, which degrade the waste water.  The majority of sewage treatment plants require an electrical supply to power either an air blower or mechanical disks or pumps.  On the majority of sewage treatment plants which use an air blower there are no mechanical or electrical components within the underground treatment zone, thus reducing future maintenance costs. 

Mantair Contracts Division has extensive knowledge in the majority of UK sewage treatment plants, including the following Brands:

All packaged sewage treatment plants we supply and install throughout Essex, Suffolk, Norfolk and Cambridgeshire meet the European Standard BS EN 12566-3.  This standard is mandatory for all ‘packaged sewage treatment plants’ up to 50 population equivalent supplied and installed throughout Europe. This standard does not cover and is not applicable to alternative sewage treatment products such as septic tank conversion units.



On the majority of projects the chosen sewage treatment plant will be delivered to our offices and inspected prior to being approved for delivery.  The sewage treatment plant is then delivered to site using one of our own transport vehicles to ensure the plant is delivered at the correct time to prevent any delays on site. 



All of our engineers are accustomed to the correct handling and installation of all makes and models of sewage treatment plants. Our trained British Water Accredited engineers ensure that care is taken at all times during delivery and installation of the sewage treatment plant to negate the potential of any damage to either the treatment plant or the clients property.



Sewage treatment plants are available to suit anything from a small country cottage to a large commercial application.  When sizing a sewage treatment plant the British Water Flows & Loads Code of Practice should be used.  For domestic dwellings the number of bedrooms is taken and 2PE (population equivalent) is added

  • House with 4 bedrooms = minimum 6PE system;
  • House with 6 bedrooms = minimum 8PE system.
