The Northern Territory Government has announced water conservation measures for Katherine to help manage the town’s drinking water supply during the upcoming peak demand period.
The Minister for Health Natasha Fyles said the measures will start 21st August to help manage water demand, particularly during the town’s peak months of September and October.
“Katherine residents deserve to have control over their lives and access to high quality services,” she said.
“Reducing the amount of water Katherine residents use will improve the ability for Power and Water to manage the quality of the town’s drinking water to help ensure the levels of Poly – Fluoroalkyl Substances (PFAS) stay within the Health Based Guidance Values."
Ms Fyles reassured Katherine residents that the monthly average PFAS levels detected through regular testing are below the national Health Based Guidance Values and the NT’s Chief Health Officer has given the reassurance that the towns reticulated water is safe to drink.
“The Northern Territory Government, Power and Water and the Department of Defence will continue to work together to effectively reduce the use of groundwater and maintain a safe drinking water supply," she said.
“The Katherine town water supply has been given the all clear by the Department of Health, however water conservation measures will be applied as an additional precautionary measure."
The Department of Defence today announced a water treatment plant will be installed towards the end of the year, another measure to assist with the management of town water supply in the Katherine region.
The Northern Territory and Federal Government are working together to manage this issue.
Minister for Essential Services Gerry McCarthy said the help of the Katherine community was needed as the build-up approached, in September and October, when water demand in Katherine increases by up to 50 per cent.
“Katherine's drinking water supply is made up of a mix of river and bore water," Mr McCarthy said.
"Our overall approach is focused on reducing the amount of bore water in the Katherine drinking water supply, because we know that bore water has higher levels of PFAS.
"This will be particularly important in the upcoming peak water usage months."
Minister McCarthy said the current daily average demand for Katherine is 10.25 megalitres per day while historical peak demand is around 15 megalitres per day during September and October.
“While we work with the Department of Defence on a long term solution, including new water sources and advanced water treatment technologies, I have asked Power and Water to instigate what we term compulsory water conservation measures, to help reduce overall demand and allow us to keep the use of ground water to a minimum," he said.
From August 21 the compulsory measures, aim to reduce irrigation frequency and increase efficiency, include the following restricted use of water:
Odd numbered properties are permitted to irrigate Monday, Wednesday and
Saturday from 6pm – 8am
Even numbered properties are permitted to irrigate Tuesday, Thursday and Sunday
from 6pm – 8am
No watering of hard surfaces
Hand held watering via a bucket or watering can is permitted at any time.
Member for Katherine Sandra Nelson said these conservation measures are an important step for the community.
"This is something we all need to work together on as a community to keep our drinking water safe," she said.
“PFAS contamination is a legacy issue that Katherine residents learned about from Defence last year and as a community we have come together to work through the issues. While our water is still considered safe under the national Health Based Guidance Values this is an important initiative that gives the community some control."
To support these compulsory water conservation measures, Power and Water will roll out its successful Living Water Smart program in Katherine.
The program has proven effective in delivering water saving solutions in the Darwin region, in particular with irrigation use and leak detection.
Minister McCarthy said finding and fixing water leaks and showing people how to save money with other really simple water saving techniques, makes good sense.
“This situation reinforces how precious our water is and that we all need to be mindful about how we use it,” Mr McCarthy said.
Water conservation measures will be reviewed in November this year.
