Central Coast Council Water and Sewer is gearing up to commence the $82.5 million major upgrade of Mardi Water Treatment Plant. Council is upgrading the Plant to ensure the security of our water supply, now and into the future. 

As part of the major upgrade, the water supply network will not be operating at full capacity at all times. During these periods, water production for the region will come from Somersby Water Treatment Plant, network storages and Central Coast Council’s connection to Hunter Water. 

Director for Water and Sewer, Jamie Loader said site works are scheduled to commence shortly, with an estimated completion of the project in late 2025. 

“As part of these works, there will be several scheduled shutdowns that will mean Mardi Water Treatment Plant will be out of service. 

“Whilst measures are in place to ensure water for the region is continued to be supplied from Somersby Water Treatment Plant and our connection to Hunter Water, turning off a water treatment plant in the network can present some level of risk to supply.

“However, Council will work hard to minimise this risk and if there is any interruption to water services, we will ensure the public is informed in a timely manner,” Mr Loader said. 

Central Coast Council Administrator, Rik Hart said the upgrade is an incredible milestone for the region’s water security.

“Upgrading Mardi Water Treatment Plant is designed to help safeguard the region’s water supply now and into the future,” Mr Hart said. 

This $82.5 million project is being delivered by Central Coast Council in partnership with the NSW Government’s Safe and Secure Water Program that has contributed $6.85 million.

The $1 billion Safe and Secure Water Program is supporting more than 250 projects across regional NSW that are in various stages of delivery.
