Regional Leakage Reduction Program

Addressing leakage

Addressing network leakage and water loss is a key priority of the Water Efficiency Program.

The need to focus on local water utilities’ network leakage and water losses became apparent during the drought and has been reinforced during consultation with councils and the wider sector as part of the Town Water Risk Reduction Program.

The department is undertaking a Regional Leakage Reduction program in collaboration with the NSW Water Directorate and local water utilities that targets the pillars of effective leakage management. The program focuses on where the NSW Government can provide the most value to local water utilities, enhancing their ability to identify leaks and target and fix leaks as part of their asset management frameworks.

Active leak detection

Thirty regional local government areas have participated in the leak detection component of the program, with more than 1,460 leaks detected thanks to the surveyance of 7,160 kilometres of water mains.

Many of these leaks have already been repaired by local water utilities, saving more than 2.6 billion litres of water per year.

The department has engaged specialist leak detectors to work closely with local water utilities across regional NSW.

Network Leakage Reduction Grants for local water utilities

The Regional Leakage Reduction Program grants have been awarded to local water utilities to help reduce non-revenue water levels. The program is co-funding selected projects with local water utilities in the areas of capacity building, pressure management, leakage control and metering.

Example projects include the supply, installation and capacity building in the use of:

• pressure data loggers
• pressure reducing valves
• leak noise loggers
• electronic listening sticks and ground microphones
• bulk and district metered area meters
• accuracy testing of customer meters.

A list of grant recipients can be found at NSW Government Grants and Funding. For more information about the program or future funding please email us at water.efficiencyprogram@dpie.nsw.gov.au.

Central NSW Joint Organisation partnership

The department is partnering with the Central NSW Joint Organisation and its member councils to reduce non-revenue water loss across 11 local water utilities.

The partnership has reduced leakage in central NSW thanks to pilot projects based on water loss maturity audits. The pilot projects will be fully delivered by the end of 2023 and are focused on the areas of pressure management, bulk metering and/or leak detection.

The Central NSW Joint Organisation partnership is also co-designing a Regional Water Loss Management Centres’ approach, that can be replicated elsewhere, combining local expertise with expert know-how  to sustainably reduce water supply network leakage.
