What Makes Mudgee's Water Unique?
Local geology and source profile
The water supply for Mudgee is drawn from Windamere Dam, located on the Cudgegong River. This reservoir serves as the primary source for the Mid-Western Regional Council's regional supply system. The raw water undergoes treatment before being distributed to residents, ensuring it meets safety standards for consumption. This comprehensive system relies on the natural characteristics of the river and the dam to provide the community's daily water needs.
The geology underlying the Cudgegong River catchment significantly influences the water's quality. The region is characterized by highly mineralized Ordovician limestone and Devonian carbonate formations. These rock types, prevalent in the Central Western Slopes, are rich in dissolved minerals, which contribute to the elevated Total Dissolved Solids (TDS) and the overall hardness of the water supplied to Mudgee.
Homeowners in Mudgee may notice the effects of hard water on their plumbing and appliances. Scale buildup can reduce the efficiency of water heaters and dishwashers, and potentially shorten their lifespan. Soap and detergents may not lather as effectively, requiring more product for cleaning. To combat these issues, regular descaling of appliances is recommended. If the hardness continues to be a concern, a water softener could be a worthwhile investment for the household.
