Rainwater Harvesting & Sewage Treatment Systems

We are approved suppliers of the Biodigester range of sewage treatment plant products.

The system is ideal for situations where no mains drainage is available. Air is blown into the treatment plant via an electric compressor which diffuses from the bottom of the central chamber.

The increase in oxygen accelerates the activity of naturally occurring micro organisms that break down and degrade solid waste matter. The air also circulates the matter 24 hours a day to ensure both chambers are fully aerobic and functioning as best as possible.
