Gosford and Wyong Councils have a two-way agreement with Hunter Water for transfers of water when supplies are low.
The Hunter Connection pipeline adds to an existing scheme linking the Central Coast with Hunter Water. The link has increased supply from six million litres of drinking water a day to 35 million litres of drinking water a day, when required.
What is the Hunter Connection?
The much anticipated 30 kilometre pipeline linking the Hunter to the Central Coast was officially opened in December 2006.
This followed extensive negotiations between Gosford City and Wyong Shire Councils and Hunter Water.
The construction of the new pipeline began in May 2006 and included building a 30km pipeline from Morisset to Warnervale, building pipelines between Balmoral and Dora Creek in the Hunter Region and building two new pump stations at Fennell Bay and Morisset.
In 2006, the first stage of the Hunter Connection Link provided the Central Coast with an annual average of 25 million litres of drinking water a day - or about 35% of our total daily usage.
In 2007, the flow increased to an annual average of 35 million litres a day. This required additional work within the Hunter Water area, north of the pipeline, and was funded by Gosford and Wyong Councils and Hunter Water at a cost of about $10.7 million.
The daily volume transferred depends on Hunter storage levels and demand. Currently in 2012 there are no transfers taking place.
The Hunter link provided immediate benefit to the Central Coast during the drought. It also provides a two-way benefit for the future, as the Hunter Connection has the capacity to transfer water back to the Hunter when needed.
A two-way sharing arrangement is therefore of benefit to both regions, and is also a great example of the inter-regional cooperation for the benefit of both communities.
The total cost of the project was $37.3 million - of which $21.1 million was jointly provided by Gosford City and Wyong Shire Councils, $9.6 million by Hunter Water and $6.6 million by the Australian Government's WaterSmart Australia Program.
The Hunter link, together with other initiatives such as demand reduction programs, sourcing more groundwater and using recycled water helped ensure that the region’s total dam storage did not fall below 10% capacity during the drought.
