Water Supply

The Councils provide water supply services from ‘catchment to tap’, i.e. they source, transfer, store and treat bulk water for distribution to customers.

Currently, the two Councils construct, operate, maintain and share the cost of the headworks system serving the water distribution system. The headworks system includes the dams, weirs, treatment plants and transfer systems between the two local government areas.

The water supply system serves a current population of around 300,000 people.

The overall Central Coast system incorporates three dams, three weirs, three water treatment plants, over 50 reservoirs, and more than 2,000 kilometres of pipelines.

Gosford and Wyong Councils take water from our dams, rivers and creeks for commercial and residential use and the remaining river flows are used for the environment.

The water supply system is continually evolving with new projects and demand management programs being implemented to match increasing demand through population and commercial growth.
