WPL Diamond DMS Range - Sewage Treatment Plant

1-20 population


The WPL Diamond sewage treatment range is ideal for domestic and commercial properties (1 up to 20 population equivalent) without access to mains drainage.

The compact design is completely below the ground with the flushest lid on the market; requiring minimal excavation and can be installed in 'wet' or 'dry' ground conditions. The kiosk, with a small footprint and lid opening, comes complete with alarm mounted beacon and reliable blowers as standard. Additional blower options are available on request.
