Mardi Mangrove Link Project
Wyong, NSW
Total funding: $120 million with $80.3 million from the Australian Government and remainder funded by Gosford City and Wyong Shire Councils.
About the project
The project involves the construction of two new pump stations and a two-way pipeline between Mardi Dam and the much larger Mangrove Creek Dam. This infrastructure will transfer water from Mardi Dam into Mangrove Creek Dam to enable more water to be harvested from Wyong River and Ourimbah Creek during high river flows.
Water stored in the Mangrove Creek Dam can be transferred back through the pipeline to the Mardi Dam when required to augment supplies.
Project benefits
The project will:
- undertake a comprehensive Environmental Flows Study to ensure the water harvesting arrangements are sustainable
- improve the water harvesting yields by increasing the pumping capacity at the lower Wyong River to enable more water to be harvested during high flows
- enable the two way transfer of water between Mardi Dam and Mangrove Creek Dam thereby enhancing overall storage management capability
- provide for a secure, reliable and safe water supply for the Central Coast to cater for current population and future growth
- protect low environmental flows downstream of the lower Wyong River weir
- reduce the pumping required per mega-litre of yield therefore reducing relative energy consumption and associated greenhouse gases
The project will advance the National Water Initiative outcomes of providing healthy, safe and reliable water supplies.
Construction began on the project in March 2010 and will be completed by June 2011.
