This Sewage Treatment Plant (STP) was designed to treat effluent to a quality that complied with the requirements of Interim NSW Guidelines for Management of Private Recycled Water Schemes – Oct 2007. To achieve the required treated water quality, an ultra-filtration unit was used in the tertiary treatment stage The treated water is suitable for toilet flushing and irrigation.

This project utilises the Extended Aeration Activated Sludge method of biological sewage treatment incorporating primary sedimentation, aeration and clarification. The system uses a CRS Model 300 packaged STP with aeration supplied via a “Roots” type blower and diffusers. Disinfection is undertaken using ORP for automatic dosing of sodium hypochlorite, followed by ultra-filtration prior to storage.
