Last year the Department of Defence advised of the presence of Per-fluorinated and poly-fluorinated alkyl substances (PFAS) in the vicinity of some of its bases around Australia, including RAAF Base Tindal, Katherine.

Power and Water is providing an important role in the monitoring of PFAS in the town water supply and is working with the Department of Defence and Department of Health to gather information and help understand the movement and levels of PFAS.


Our current activity

Power and Water carries out an extensive sampling program throughout the year on its drinking water sources, in accordance with Department of Health and the Australian Drinking Water Guidelines.

We are undertaking regular sampling of drinking water in Katherine. Testing for PFAS is conducted by laboratories interstate. Results of tests are provided to the Department of Health. For more details visit our PFAS page.

Groundwater is needed to blend with river water to provide Katherine’s drinking water. PFAS levels are highest in the groundwater.

Power and Water has adjusted the blend to reduce the use of groundwater to the minimal level and lower the presence of PFAS . During the period of peak demand and when the river level drops we need the community of Katherine to help us by using less water, reducing our reliance on groundwater.

This has highlighted the need to work together to assist in keeping Katherine’s drinking water source safe and reliable.

Our shared responsibility

The Northern Territory Government and Power and Water are committed to providing safe drinking water to the Katherine community.

The PFAS situation has highlighted how we all need to work together to ensure Katherine’s water resources remain safe and reliable. To support this, the Northern Territory Government has introduced compulsory water conservation measures.
Power and Water has already commenced working with major water consumers across Katherine to reduce their use.

By working together and smarter, we can conserve Katherine’s water.

Compulsory water conservation measures

Due to the presence of PFAS in water around Katherine, the Northern Territory Government has introduced compulsory water conservation measures to take the pressure off our groundwater supplies. This means:

  1. ODD NUMBERED properties can only water three days a week on Mondays, Wednesdays and Saturdays from 6pm to 8am.
  2. EVEN NUMBERED properties can only water three days a week on Tuesdays, Thursdays and Sundays from 6pm to 8am.
  3. No watering of hard surfaces such as concrete or paved driveways, footpaths, street gutters and road areas.

Katherine’s water use is currently twice the national average and this needs to be reduced by around 20% to ensure water supplies remain sustainable.

It is important that we all work together to ensure Katherine’s water resources remain safe and reliable, both now and in the future.

Our Living Water Smart team will work together with the local community to reduce water use.

Katherine is one of the highest water users in the country at around twice the national average. Living Water Smart has found that one of the largest areas of water waste is through leaks. In fact, one in five Katherine properties has a leak,  wasting around 500 000 litres of water or about $1000 per year on average. Living Water Smart is implementing a Community Leak Program to identify and fix leaks.
