Water supplies

Power and Water supplies drinking water through more than 250 production bores, 160 water storage tanks and 600km of water distribution systems spread across the Territory.

Water is provided to residents for drinking using cost-effective systems, where a number of production bores pump water from the underground aquifer to a central storage area where the water is disinfected and delivered via the distribution system using gravity.

In 68 towns and communities the water primarily comes from groundwater, contained in underground water bodies known as aquifers, which is extracted through production bores. The remaining three communities use surface water sources such as rivers, creeks and dams.

All the water supplies are disinfected before it is delivered to customers to drink.

Power and Water's Water for Healthy Communities initiative ensures appropriate water and sewerage services in major remote towns and remote communities, which includes water quality, water sustainability and wastewater management. This integrated approach is based on the principles of risk management, which focuses on adequate and safe water being available for communities and then after the water has been used, the treated wastewater is appropriately returned to the catchments. 

Water quality

Power and Water works with the Department of Health to manage drinking water quality. We have a Memorandum of Understanding outlining the actions to be taken when water quality tests identify issues including when E. coli is detected in the water.

In some instances, the Department of Health will take an extra protective step and advise the community that drinking water should be boiled before consumption to destroy potentially harmful organisms in the water.
