About Westernport Region Water Corporation
The core function of Westernport Water is to provide water and wastewater services wherever economically, environmentally and socially practicable to properties and communities throughout its district.
It services over 17,300 customers across an area of 300 square kilometres on Phillip Island and the mainland stretching from The Gurdies to Archies Creek.
Westernport Water has a diversified water supply with water sourced from the catchment supplying the Candowie Reservoir (located in the Bass Hills near Glen Forbes) via Tennant Creek, the Bass River and ground water bores from the Aquifer.
The water is treated at Ian Bartlett Water Purification Plant (IBWPP) at the Candowie Reservoir and then pumped to the San Remo Basin for distribution to customers within Westernport Water's district, with average annual system demand of approximately 1,900ML (or 1.9GL).
Westernport Water has two wastewater treatment plants which process 1100 megalitres (ML) of domestic wastewater each year.
The Cowes Wastewater Treatment Plant (CWWTP) is the main plant treating 90 per cent of waste by volume. The secondary plant, the King Road Wastewater Treatment Plant (KRWWTP) in Coronet Bay, treats the remaining 10 per cent of waste by volume. Both accept domestic waste only. The CWWTP can treat up to 8.5 ML per day and the KRWWTP can treat up to 0.35ML per day. Westernport Water supplies wastewater services to 90 per cent of properties that receive water.
Westernport Region Water Corporation (Westernport Water) is one of 19 water businesses operating in Victoria and reports to the State Government of Victoria.

Westernport Water is responsible for its own management and performance, and for supplying water and sewerage services to customers on Phillip Island and the district between The Gurdies and Archies Creek.
