Water and Sewerage Services
Power and Water manages both surface and ground water supplies in the Northern Territory.
Darwin is the only main centre with a dam for water supply. Darwin River Dam was built in 1972, with a 205 square kilometre catchment area.
The spillway wall was raised 1.3 metres in 2010 and 2011, increasing the potential water storage by about 30 per cent to cater for increased demand for water in Darwin and the surrounding area. However, we do continue to look at other potential water sources.
Alice Springs, Darwin, Katherine and Tennant Creek all have borefields to source water. Alice Springs and Tennant Creek are completely reliant on groundwater.
Alice Springs in particular is costly to operate because the electronic bores source water from about 150 metres underground.
Delivering water in the Territory requires thousands of kilometres of water pipes. Power and Water's Leak Detection Van routinely monitors many of these using sensors to electronically monitor pipe movements and track down leaks.
Drinking water is routinely sterilised with chlorine to ensure it is safe to drink. The exception to this is in Tennant Creek, where residents voted against routine chlorination. The water supply is closely monitored and hand sterilised when required.
If you intend to connect a new property or subdivision to the water distribution system, the guidelines listed left will help you through the process.
