WaterPlan 2050 - Mardi - Mangrove link |
updated: 08/07/08 |
The Mardi-Mangrove Link This project is a key plank of WaterPlan 2050, the strategic blueprint developed by the two councils to manage and secure the Central Coast’s water resources over the next four decades. It’s also the largest water infrastructure project undertaken on the Central Coast since the mid 1980s when Mangrove Creek Dam was built. Based on questions that the Project Team has been frequently asked, this section is designed to answer queries and provide a good idea about what is going to happen next. • Pipeline route selection process If you have additional questions, contact the

The key focus of the project over the past eight months has been on identifying a recommended route for the 19 km pipeline through Yarramalong Valley. This has involved detailed engineering, environmental, geotechnical and heritage studies combined with extensive and ongoing consultation with potentially affected landowners, the Yarramalong Valley community and other interested parties. What is the Recommended Pipeline Route? A recommended route has now been identified for eight out of the nine sectors that make up the entire 19 km pipeline route to connect Mardi Dam to the existing Bunning Creek Tunnel. Considered and accepted by the Gosford/Wyong Councils’ Water Authority (GWCWA) at its scheduled Board Meeting on 21 May 2008, this recommended route is now subject to approval by the two Councils.
What’s happening with Sector Six of the Pipeline route? For the one remaining sector, Sector 6 (an area from 600 metres West of Boyds Lane to 1248 Yarramalong Road), further detailed:
Work will be undertaken for all of the routes currently under consideration over the next three months, subject to the prior approval by the two Councils. This additional work is needed because each of the routes investigated in this sector have specific challenges that need to be overcome. Once this work is complete, the Project Team will make a further recommendation about the pipeline route for Sector 6 that will be considered by the GWCWA Board and then the two Councils.
Five key criteria were then identified based on both the Project Team’s own knowledge and experience in building pipelines as well as community feedback, which had identified these criteria as being upper-most in the minds of local residents, the Central Coast community in general and other interested parties.
Six independent experts scored each sector across
the five selection criteria. The scoring system
was based on: Each score was reviewed by other panel members
to validate rationale and ensure consistency.
Overall route scores were then subject to a sensitivity
analysis to test their robustness. The lowest
scoring outcome determined the route chosen for
that sector. The construction contractors will also work very closely with all affected landowners as well as the Yarramalong Valley community in general. Outside of the Valley, the Project Team will continue to provide regular updates to the Central Coast community through the two Councils’ normal information sharing mechanisms including the local media. Briefings are also regularly provided to the
elected Councillors, State and Federal MPs in
the region as well as all other interested parties. Information about the Mardi-Mangrove Link project can be obtained by e-mail or by telephoning the Project Office on (02) 4350 1676
