THE NSW Government’s Safe and Secure Water Program has invested $6.85 million along with over $75 million from the Central Coast Council to build a world-class water treatment plant that will provide up to 160 million litres of clean water every day.

 

Minister for Water Rose Jackson said it is the first time since 1992 the plant has been upgraded which was great news for the community because it will help secure the region’s water future for the next five decades by improving treated quality and reliability.

 

“While it has been a faithful workhorse for the past 40 years, the time has come to overhaul the technology and modernise the infrastructure to keep up with the demands of a growing community while shoring up water security,” Ms Jackson said.

 

“Water treatment plants are a community’s first and last line of defence when it comes to producing safe drinking water. It is crucial the infrastructure can cater for an increasing population and be a reliable source of water in both the wet and dry times.

 

“Bringing the plant’s technology into the 21st century will enable it to treat raw water to an even higher standard, particularly during low flow periods when there are increased levels of sediment and organic material, including algae, that need to be treated.”

 

Minister for Central Coast and Member for Wyong David Harris said the upgrade is a major win for the Central Coast community.

 

“Our community is growing and a modern, secure water supply is a must,” Mr Harris said.

 

“These important infrastructure upgrades are vital for the health of our community, economy and environment.”

 

Central Coast Council Director of Water and Sewer Jamie Loader said the project is now moving into the design phase with construction just around the corner, which will be a huge milestone.

 

“The Mardi Water Treatment Plant provides about half of all drinking water to the Central Coast and transfers extra supply to the Hunter region, so future proofing this asset and delivering safer and more secure water is a key priority,” Mr Loader said.

 

“It’s exciting to see progress being made and we’re looking forward to the finished product which will treat up to the equivalent of 64 Olympic swimming pools of top-notch treated drinking water for 210,000 homes and businesses across the Central Coast and parts of the Lower Hunter.”

 

This is one of the largest water infrastructure projects undertaken by council since the Mardi to Mangrove pipeline, which was completed in 2011.

 

Central Coast Council Administrator, Rik Hart congratulated Abergeldie Contractors Pty Ltd on being awarded the contract.

 

“Mardi Water Treatment Plant was built in 1982 with the last major upgrade of the facility completed 10 years after that. It’s time that we give this asset a significant makeover, allowing it to cater for future growth and climate related risks.

 

“Once finished, Mardi Water Treatment Plant will be able to treat up

 

Construction is expected to start in the first half of 2024 and be completed in late 2025.
