What Makes Goonellabah's Water Unique?
Local geology and source profile
Goonellabah's water originates from two key sources managed by Rous Water, which supplies Lismore City Council Water. The primary reservoirs are Rocky Creek Dam, fed by the Brunswick River, and Emigrant Creek Dam. These Northern Rivers hinterland reservoirs form the backbone of the region's water supply. The water is then treated before being distributed to residents, ensuring a consistent flow to the community.
The water's journey begins in the Northern Rivers plateau, where the catchment area is predominantly composed of basaltic rock. This geological makeup is what gives the water its characteristic slight hardness. The moderately mineralised basaltic hinterland imparts dissolved solids, contributing to the overall mineral content that defines the water's quality as it flows from the earth and into the storage dams.
Homeowners in Goonellabah may notice that this slightly hard water can lead to a build-up of scale over time, particularly in appliances like kettles and water heaters. While not typically a major concern for taste, it can affect the efficiency and lifespan of these items. Regular descaling can help manage this, and for those sensitive to mineral content or wanting to protect sensitive equipment, a water softener could be considered.
Geology & Source: Northern Rivers basaltic hinterland; basaltic rock produces slightly hard water
