What Makes Ocean Grove's Water Unique?
Local geology and source profile
Residents of Ocean Grove receive their water from Barwon Water, primarily through the Bellarine Pipeline. This important infrastructure connects to the Barwon River, and may also draw from the Bellarine aquifer. The water undergoes treatment before reaching homes, ensuring a consistent supply for the community.
The water serving Ocean Grove originates from the Barwon River and potentially the Bellarine aquifer, drawing from the basalt plain geology of the Bellarine Peninsula. This geological makeup, characterized by basaltic rock, contributes to the water's moderately hard classification. The blend of Barwon River water with other sources results in water that is harder than that supplied to central Geelong.
Homeowners might notice that this moderately hard water can leave scale deposits on fixtures and inside appliances over time. To combat this, regular descaling of kettles and showerheads is recommended. While not excessively hard, some residents may prefer to install a water softener to further reduce mineral content, which can improve soap lathering and potentially extend the lifespan of hot water systems and dishwashers.
Geology & Source: Barwon River basalt plain geology; basaltic rock produces moderate hardness
