Septic Tank Conversion Unit

GEM Sewage Treatment Unit - up to 12 persons

Can also convert a septic tank to a full sewage treatment unit

The GEM can be installed as a complete sewage treatment unit by the addition of a settlement tank, (usually a septic tank) prior to it, or you can use an existing septic tank. It is capable of treating the effluent from up to 12 people (resident) or 28 office/factory staff to UK and the new EU wastewater standards for direct discharge to a watercourse. This is a high quality POLYETHYLENE tank, manufactured in UK. The unit can also be used to after a sewage treatment unit that is failing to meet the consent to discharge standards

BENEFITS

NO internal electrical or mechanical moving parts - NO biodiscs, bearings, belts, motors to replace
Low maintenance costs
Small footprint - only a small lid flush with the ground
