Coastal treatment facilities have been designed to protect the region's beaches, which are some of the most popular holiday and recreational destinations in Australia. Barwon Water operates nine sewage treatment plants. Land-based treatment consists of two primary lagoons and a small maturation lagoon.
Treated effluent is used to irrigate woodlots on the site.
On average 270 kilolitres of sewage is received each day. Serves the coastal township and treats around 0.7 megalitres a day. A natural biological process combines with ultra-violet disinfection at this plant to produce a clear effluent suitable for reuse or ocean discharge. The plant is designed to handle flows up to three million litres a day during summer when holidaymakers swell the area's population. It is Barwon Water's largest treatment plant and the largest plant of its type in Australia.
