Wyong, New South Wales
Australian Government Funding: $80,300,000
About the project
The project involved the construction of two new pump stations and a two-way pipeline between Mardi Dam and the much larger Mangrove Creek Dam. This infrastructure transfers water from Mardi Dam into Mangrove Creek Dam and enables 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.
The project has:
- improved water harvesting yields by increasing the pumping capacity at the lower Wyong River which has enabled more water harvesting during high flows
- enabled the two way transfer of water between Mardi Dam and Mangrove Creek Dam thereby enhancing overall storage management capability
- provided a secure, reliable and safe water supply for the Central Coast to cater for the current population and future growth
- protected low environmental flows downstream of the lower Wyong River weir
- reduced the pumping required per mega-litre of yield therefore reducing relative energy consumption and associated greenhouse gases
The project is now complete and the commemorative book is available below.
