Supplying safe drinking water is Power and Water’s highest priority. We are committed to providing drinking water that is consistent with Australian Drinking Water Guidelines to 72 remote communities in the Northern Territory.
The Australian Drinking Water Guidelines (ADWG) framework promotes the application of a ‘multiple barrier’ approach to the provision of drinking water. Multiple barriers are in place so that if one barrier fails, other barriers still prevent or reduce potentially harmful contaminants from reaching consumers.
Ensuring that water supplies are continuously disinfected is an essential barrier to reducing consumers’ exposure to disease-causing micro-organisms. Chlorine is the preferred purifier as it is simple to use, destroys pathogenic micro-organisms effectively and provides protection through the distribution system.
Additional water treatment processes are used to improve the quality of water supplied to a number of communities. This involves the raw water being treated before being disinfected and distributed to the community. Treatment methods used include filtration and aeration.
The water quality at all communities is monitored regularly to ensure that the drinking water supplied is consistent with the Australian Drinking Water Guidelines. Monitoring includes both regular collection of samples to test for microbiological contamination and daily testing for chlorine residual to ensure effective disinfection.
