Muswellbrook Water Treatment Plant (May 2004)

At Muswellbrook Water Treatment Plant, river water is pumped to a clarifier where lime and ferric sulphate are added to reduce hardness. The water treatment plant is semi-automatic and will shutdown if the turbidity of the raw water rises above set limits. The clarified water then goes to the recarbonation chamber where the pH of the water is adjusted to about 8.0.

The water then passes through three rapid sand filters. Sodium hypochlorite is added to the water, and finally fluoride. From here the treated water is pumped to the reservoirs which supply the town with water by gravity mains. In areas of higher elevation in Muswellbrook, booster pumping stations are used to supply sufficient water pressure. High elevation areas in south Muswellbrook are supplied from Acacia reservoir.
