Mardi-Mangrove Link Project is a key element of WaterPlan 2050, the long term water supply strategy for the Central Coast. This project will help secure the region’s town water supply over the next four decades by linking Wyong River and Ourimbah Creek to Mangrove Creek Dam, via Mardi Dam.
The Link means that during high flows water can be transferred to the large Mangrove Creek Dam for storage instead of allowing it to flow to the ocean.
The Mardi-Mangrove Link pipeline is the largest water infrastructure project undertaken on the Central Coast since the mid-1980s when Mangrove Creek Dam was built.
It involved building:
- a 2.1 kilometre buried water pipeline from Wyong River to Mardi Dam through Mardi
- a 19 kilometre buried pipeline from Mardi Dam to the existing Bunning Creek Tunnel at Mangrove Creek Dam, running through Yarramalong Valley
- a new pump station at Mardi Dam
- a new pump station beside Wyong River
- and associated works.
The Central Coast community will benefit from the Mardi-Mangrove Link as it will help to boost dam storage levels, speed up drought recovery and help protect the region against future extended periods of below average rainfall.
The project was an initiative of the former Gosford City and Wyong Shire Councils with Australian Government funding of $80.3 million from the Water Smart Australia Program and an additional $40 million combined from the two Councils.
The official system launch of the Mardi-Mangrove Link took place on 31 August 2011.
