Who does it supply?
The Grampians Water Supply System is our oldest – dating back to 1900 and supplying water for customers in:
- Cavendish
- Dunkeld
- Hamilton
- Tarrington.
Where does the water come from?
Balmoral’s water is sourced from Rocklands Reservoir. It’s treated using a filtration and disinfection process at a local treatment plant.
We source Cavendish’s water from streams or bores in the Grampians. It’s treated using UV and disinfected before we deliver it to around 100 customers.
Water for our 6,100 customers in Hamilton, Dunkeld and Tarrington comes from streams in the Grampians. During dry periods, we can take extra water from Rocklands Reservoir or shallow groundwater bores in the Grampians.
Where is the water stored?
The water is stored in Hayes, Cruckoor and Hartwichs reservoirs, allowing the different raw water qualities to blend together. This also allows sediment to settle before the water is sent to the Hamilton Water Treatment Plant
