About the project

In 2020, Shoalhaven Water created a list of water and sewer mains that were at risk of breaking or reaching the end of their lifespan. The identified mains were prioritized based on their criticality, class, size, breakage history, and location.

By renewing, upgrading, or replacing these mains, Council expects a reduction in water main breakages, improved water pressure, and a more robust water distribution system.

The renewal, upgrading or replacement of these mains will be executed as distinct work packages over several years.

About the packages of works

Nine work elements are proposed to be executed within this package of works, across several suburbs. Read more about each package below.
