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 and Sunbury (Rosslynne) districts. After many years of prolonged drought, which dramatically reduced water levels, recent record rainfall has boosted local reservoirs.
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 parts of 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 and parts of Melton will continue to receive water from Melbourne’s Silvan Reservoir. Other customers may have Melbourne water added to their local supply at times.
