In the area previously serviced by Western Water, we use several water sources to supply customers.
Having access to multiple sources ensures we can meet demand, cater for a growing population and manage water supplies when inflows are low.
When local supplies are low, or reservoirs are at decreased capacity, supply changes ensure our customers have access to water that is safe, healthy to drink and meets the Australian Drinking Water Guidelines.
When water supply changes take effect, some customers may notice a slight change in taste. This is due to the different water treatment processes we use for local source water storages, compared to when drinking water is sourced from Melbourne.

* These towns only receive fluoridated water when supplied with water from outside their normal water source. For example, in times of drought water may come from Melbourne or be brought in from other sources. The long-term levels of fluoride during these times are below what is expected from a normal fluoridated water supply. For more information about fluoride, visit the Department of Health and Human Services website or call their hotline on 1300 761 874.
