What Makes Mudgee's Water Unique?
Local geology and source profile
Mudgee's drinking water is supplied by Mid-Western Regional Council, drawing from Windamere Dam on the Cudgegong River in the Central Western Tablelands of New South Wales. Water hardness in Mudgee is measured at 192 mg/L — classified as hard, approaching the Australian Drinking Water Guidelines (ADWG) aesthetic guideline of 200 mg/L published by NHMRC. Mudgee — a prosperous regional wine and agricultural town on the Cudgegong River in the Central Western Tablelands, known as one of NSW's premier wine regions with the Mudgee Wine Festival, home to the Mudgee Regional Airport, the pastoral agricultural industry of the Cudgegong River valley, and the heritage colonial streetscape of the regional town centre — receives hard supply from the Windamere Dam Cudgegong catchment system.
Mudgee's hard supply reflects the Windamere Dam catchment geology on the Cudgegong River in the Central Western Slopes. The Cudgegong catchment traverses a geologically complex terrain of Ordovician limestone and Silurian carbonate sequences, Devonian volcanic intrusions, and the Lue goldfield Permian–Carboniferous sedimentary formations of the Central Western Slopes — geological terrain contributing significant dissolved calcium, magnesium, and carbonates to the Windamere Dam supply. At 192 mg/L and TDS 454.2 mg/L, the Mudgee Cudgegong regional supply is notably hard for a dam-sourced regional NSW town, reflecting the carbonate-rich catchment geology of the Central Western Slopes.
Mudgee residents face moderate-to-significant limescale build-up on taps and in kettles — descaling every four to six weeks is typical. Hot water systems benefit from regular inspection. The elevated lead reading (0.005 mg/L) warrants briefly running the cold tap before use. Mid-Western Regional Council provides water quality information online, with all ADWG health standards consistently met. Mudgee's wine industry community and the Cudgegong River agricultural region benefit from a safe supply meeting all ADWG standards.
Geology & Source: Supplied by Mid-Western Regional Council from Windamere Dam on the Cudgegong River — the Mudgee Central Western Tablelands regional supply carries hard water at 192 mg/L with elevated TDS of 454.2 mg/L, reflecting the highly mineralised Ordovician limestone and Devonian carbonate geological formations of the Central Western Slopes Cudgegong River catchment producing hard water at Mudgee.
