The Safe and Secure water security projects include the installation of an artesian bore, the construction of an off-stream water storage facility, and improving or constructing sewage treatment plants and reservoirs.

The sustainable Narromine water supply project will include a scoping study investigation into additional bore and water treatment facility to improve water security for Narromine.

Minister for water, property and housing Melinda Pavey said NSW communities depend on access to clean water, and wastewater infrastructure that meets environmental and health standards.

"This drought is outside the history books, while we continue to invest in emergency water infrastructure we must ensure we are maintaining our regional water infrastructure and investing in the future of our communities," Mrs Pavey said.

"The program prioritises key water infrastructure projects - from local drought backup systems through to new or upgraded dams to secure water supplies for our regional communities.

"The NSW government will continue to work with local councils to provide water infrastructure that improves the lives of over 1.9 million people living in more than 500 regional NSW communities."

While local councils are the water utility provider for their communities, the state government will continue to help them where we can in getting through this difficult time.

The program is a $1 billion regional infrastructure co-funding program established under the NSW government's Restart NSW fund.
