Cowarra Water Treatment Plant

Cowarra-1140x350px.png

Our local government area currently has an estimated population of 86,400. By 2041, our community is projected to grow by 16.5% to a population of approximately 100,700.

We are proactively planning for an increased demand on our communities’ drinking water, to ensure that we have the capacity to continue providing safe and secure water.

At the moment, we have several water supply schemes in operation. The Hastings Bulk Water Distribution Scheme is comprised of the systems that send water to Wauchope, Port Macquarie and Camden Haven. The smaller communities of Comboyne, Long Flat and Telegraph Point have their own water supply schemes.

To sustain our growth, we’re constructing a new bulk water treatment plant (WTP), just south of Cowarra Dam. The water treated here will be distributed to Sancrox, Thrumster, Port Macquarie and Camden Haven communities, which are identified as key areas of growth.

We are committing a significant investment for this upgrade to ensure the security of supply, and enhance the quality of drinking water for the community.

What are the proposed works?

Construction of a new bulk water treatment plant (WTP), just south of Cowarra Dam.

In conjunction, we will construct a clear water reservoir and northern arm trunk main from the reservoir to the water distribution systems of Sancrox, Thrumster and Port Macquarie.

We are also continuing the construction of the southern arm trunk main along Houston Mitchell Drive to directly connect to the Camden Haven water distribution system.

Project benefits

This project looks to:

  • increase water supply to address future demand
  • enhance water security during low and high rain events
  • maximise water supply and optimise network storage
  • upgrade the water supply system to ensure reliable delivery of water to the community
  • provide multiple barrier treatment to improve water quality
  • improve reliability, redundancy, and resilience of our regions water supply infrastructure.
