The Ian Bartlett Water Purification Plant (IBWPP) was constructed in 1990 to improve drinking water quality and is located in the Bass hills near Glen Forbes.
The IBWPP at Candowie Reservoir supplies water to our customers via a large water main. This main delivers water to the San Remo storage basin, which then delivers water to the mainland and to Phillip Island.
Raw water from Candowie Reservoir is treated using a combination of oxidation, adsorption, flocculation, coagulation, dissolved air flotation, filtration, pH correction, fluoridation and disinfection at the IBWPP.
The source water is predominantly high in nutrients and organics, and quality is typical of water that is sourced from an open, unprotected catchment. Below highlights the treatment process used at IBWPP.
