It all adds up to this third year of water restrictions potentially being a struggle through the dry season.

Water use is already rising to worrying levels despite the restrictions with the build up heat just around the corner.

Water authorities say Katherine's water use has already risen to nine megalitres a day when they can safely provide 10 megalitres of PFAS free water per day.

A new water treatment plant is to be constructed from the end of this year to hopefully end Katherine's water torment.

Residents hope this will be the final year of the odds and evens restrictions now a new water treatment plant is to be built, guaranteeing a PFAS-safe water supply for the town.

But for now, water authorities are using a smaller emergency plant to treatment their contaminated bores, while the Katherine River is at one of the lowest levels in living memory after a poor last wet season.

The odds and evens system for household watering is continuing with no watering on Fridays.

Meanwhile, Power and Water Corporation says leak checkers will be walking the streets of Katherine again next week.

To avoid even stricter restrictions so supplies can be guaranteed, Power and Water's Living Water Smart team will be in Katherine next week to identify potential leaks in residential homes.

The program has previously identified more than 1100 potential leaks in Katherine homes in 2017 and 2018, uncovering 260 megalitres of leaking water.

During the past two years, more than 900 residents have taken advantage of a $200 Leak Find and Fix rebate to locate and repair leaks.

Jethro Laidlaw, Power and Water's Living Water Smart program manager, praised the Katherine community on how well it has done becoming more water efficient, however is also concerned about the amount of water still being lost through leaks.

"Since the program started in 2017, we have found more leaks than expected. Around one in five homes had a leak, with the average leak being 230,000 litres per year - the same as tipping 958 wheelie bins of water down the drain."

Over the next two weeks our leak checkers will re-visit all Katherine homes to check the water meters for signs of leaks, including where leaks were previously found to check that they haven't recurred.

"Thank you to the Katherine community for demonstrating their commitment to save water. We all need to continue work together, as the more water we save, the less stress there is on our water supply," Mr Laidlaw said.

If leaks are found at properties, leak checkers will leave a reminder card in the mailbox and details about the $200 Leak Find and Fix rebate that is available through local plumbers registered with the program.

Residents are encouraged to access this program again and have these leaks fixed.

"Keep an eye out for our friendly leak checkers on the street and feel free to ask them more about the Leak Program and rebate".

The Living Water Smart team will also be visiting some larger businesses and organisations where leaks were identified and helping them with their water management plans.
