Forster Water Hardness & Quality Report (2026)

The MidCoast Council supplies water to Forster and neighboring communities in New South Wales, including Tuncurry and Pacific Palms. The main water source is the Manning River, with support from reservoirs like Booti Booti and possibly local groundwater. Treatment occurs at the Forster Water Treatment Plant, which serves around 20,000 people in the Forster-Tuncurry area and nearby coastal towns. This supply originates from the Manning River watershed, stretching from the Barrington Tops plateau to the coast. The catchments contain Permo-Triassic sedimentary rocks and overlying basalt flows from the Liverpool Ranges.

Geologically, the area is characterized by Permo-Triassic sandstones and shales, part of the Sydney-Gunnedah Basin margin, alongside Quaternary coastal sands and estuarine deposits. These formations, particularly the lack of significant limestone or dolomite, mean the water is naturally soft. Unlike regions with karstic drainage, this area doesn't have substantial sources for dissolving minerals like calcium and magnesium. Granitic intrusions and basaltic outcrops contribute minimally to the water's mineral content, reinforcing its soft water profile.

Because the water is naturally soft, you won't typically find scale buildup in appliances like kettles or dishwashers, and your hot water systems are less likely to suffer from limescale. This can help extend the lifespan of your plumbing and appliances, meaning less need for descaling. You'll also find that soap lathers easily, potentially reducing the amount of detergent you need. While soft water is generally good for appliances, some people find it can leave a slightly flat taste or a faint film on fixtures. A water softener isn't necessary here and could add unwanted sodium to your supply.
