Commercial Grey Water Treatment Systems


Enviro Plumbers is a supplier of the latest technology in grey water recycling.

Grey water recycling in apartment blocks, hotels, schools, townhouses and commercial buildings is now feasible using Nubian’s OASIS grey water recycling process in the system design.

Property investors, offering sustainable “Green Buildings” to environmentally responsible tenants, can install economic OASIS systems that save substantial amounts of drinking water – up to 60% of conventional usage patterns.

This grey water system is already applied in a range of active projects in apartments, offices, hotels, schools and mine sites throughout Australia.

The OASIS technology is Australian with global patents pending. It uses the well proven wastewater treatment processes of solids separation, biological treatment and ultraviolet disinfection. The biological treatment step is the heart of the technology, and is an innovative form of aerated biofilter, which provides very high rate processing and is very robust in its ability to deal with varying and shock loads, which are typical of residential greywater.


Treated water is of a high quality, with BOD and Suspended Solids levels typically less than 5 ppm. The high UV dosage consistently delivers Faecal Coliform levels close to zero. The system is fully automated, and is designed to require no user intervention between scheduled service calls. On-line and remote monitoring devices can be added, and these can integrate with building automation systems.

Property developers will use clusters of these systems in large estates, processing grey water and irrigating common land, gardens and even reticulating into groups of houses. Recycling treated water back into residences can reduce drinking water by more than 40% and sewer discharge by 60% - promising substantial savings in capex reticulation of sewage processing facilities and ongoing charges.

The Oasis grey water treatment system makes achieving environmentally responsible buildings a lot easier.
