***Septic Tank Is NOT Included and For Illustration Purposes Only***

This Marsh Uni:Gem Septic Tank Conversion Unit is suitable for domestic installations where the population equivalent doesn't exceed 6 PE (upto and including a 4 bedroom house). The Uni:Gem is installed behind an existing onion septic tank of upto 6PE and converts the existing system into a sewage treatment plant which complies with the General Binding Rules for small sewage treatment plants for domestic use.

It operates by the effluent from the existing septic tank, gravity feeding into the Uni:Gem aeration chamber where it is treated to remove disolved constituents. In here aerobic bacteria, supported by a low power 240v air blower, diffused air and mobile media, ensures full treatment is achieved before the treated effluent (and "sloughed off" bacteria) flows to a final settlement chamber prior to discharge to river, ditch or watercourse.

All Uni:Gem units are provided with an external compressor and housing. The external compressor is supplied with 4m of air hose. Gravity outlet is standard, however pumped outlets can be provided as a costed option, if selected pumped outlets are provided as a seperate pump station which is installed behind the Uni:Gem.

This Uni:Gem can be installed in granular or concrete backfill, depending upon ground conditions. Both backfill options require a concrete base. As-dug material or soil is not a suitable backfill material. If the water table (at any time of year) rises above the proposed base of the tank, it must be installed in concrete. If the ground is not free-draining (eg.clay, silt or similar), the tank must be backfilled with concrete. Failure to select the correct backfill material for the ground conditions will invalidate the manufacturer's warranty.

As ground conditions and water table levels can change over the expected life of the tank, we strongly recommend at TFE that all tanks be concrete-backfilled to prevent future issues.
