*When Garden Hut Reservoir and the Lancefield Service Basin are at low
levels, bore water may be used as part of the Lancefield water supply.
The Western Water region has two main water storages, Rosslynne Reservoir and Lake Merrimu, both of which are managed by Southern Rural Water. The reservoirs supply the Melton and Bacchus Marsh (Merrimu) and Macedon Ranges (Rosslynne) districts.
After a period in which almost 90% of the region’s drinking water was supplied from Melbourne Water catchments, we are now returning to local water sources. Customers in Bacchus Marsh and Melton are receiving water from Merrimu Reservoir and customers in Gisborne, Macedon and Riddells Creek will soon be receiving water from Rosslynne.
Customers in Sunbury will continue to receive water from Melbourne’s Silvan Reservoir. Other customers may have Melbourne water added to their local supply at times.
