Drinking water quality and testing

We regularly test drinking water to make sure the supply is safe. Learn more about water quality in your area.

Water supplies across the Tasman District from Murchison to Collingwood are regularly tested. None of our water supplies have fluoride added.

Individual supplies

In addition to regular testing for public health, people interested in home brewing will find water quality information useful. In addition, Some newer dishwashers also require 'hardness' information.

Note that if you need ‘hardness’ in mmol/l, rather than mg/l as CaCO3 (as reported here, simply divide the reading by 100 to get an approximate answer. (e.g. Richmond 135mg/l becomes 1.35mmol/l).
