At Sandy Hollow Water Treatment facility, water is pumped from bores on the Goulburn River and recycled through an ozone treatment. This precipitates dissolved solids such as iron and manganese, which although not harmful to health, may cause staining in washing etc. This allows these solids to be captured by the filtration system. After filtration the water is chlorinated. This treated water is then pumped into reservoirs; from here it gravitates to consumers in town.
