Central Coast Council is the local government area serving the Lower Hunter area and Central Coast region of New South Wales. 

To date, the Mardi to Warnervale Pipeline is the largest infrastructure project ever delivered by the council. 

Operational since March 2021, the 9.4 km pipeline has transferred 2,400 megalitres of water, equivalent to 1,000 Olympic swimming pools. 

The pipeline runs from the existing Mardi Water Treatment Plant to Sparks Road at Warnervale and will service expansion in the major growth corridor. 

Council director for water and sewers Jamie Loader said the pipeline boosts water security for the rapidly growing northern suburbs as well as the entirety of the region. 

“Since completing this critical piece of water supply infrastructure we have moved significant volumes of water to service the Coast’s major northern growth corridor including Warnervale Town Centre,” Loader said. 

“The pipeline runs from Mardi Water Treatment Plant right through to Sparks Road at Warnervale and enables bulk water transfers – up to 30 megalitres a day – between the Central Coast and Hunter.

“Increasing our capability for bulk water transfers between the Central Coast and the Hunter improves water security for both regions.

The pipeline is 1 m in diameter and passes through rural land holdings, around the outer edge of Watanobbi, and along the fringes of environmentally sensitive wetlands. 

“Through extensive research and community consultation we selected the most suitable route for the pipeline and used build techniques such as trenchless construction to ensure environmentally sensitive areas were protected,” said Loader. 

The Mardi to Warnervale Pipeline was delivered ahead of schedule and under budget, despite the impacts of COVID-19. 

Though it was forecast to cost $61 million, the Council was able to deliver this integral piece of infrastructure for $49.1 million.
