Sustainability at work
Working with clients such as the City of Onkaparinga provides TRILITY with the opportunity to demonstrate its expertise in developing affordable methods of providing wastewater and reuse services to regional communities.
This project was developed with the client and provided a template for delivering small privately financed projects in regional areas. Community Waste Management Schemes (CWMS) are schemes where septic tank effluent is collected via a common pipe system for treatment. They are an affordable method of providing sewage services to small regional communities which may not have the population base to warrant the capital expenditure necessary to provide full treatment services. These schemes are traditionally delivered by local government.
Under the Onkaparinga Reuse Scheme, septic tank effluent is collected from McLaren Flat, McLaren Vale and Willunga, treated in a purpose built wastewater treatment plant and discharged to the City of Onkaparinga’s existing storage dam at Willunga where it is subsequently pumped to vineyards and a neighbouring golf course.
TRILITY also implemented a SCADA system which monitors the entire reuse network, including the wastewater treatment plant and pumping station, which is controlled by remote access. The wastewater treatment plant is an extended aeration plant which is a common and well-established process in Australia. The plant has a peak wet weather capacity of 3 ML/d.
