We've commenced the first stage of a major ten-year-plus program to renew and upgrade the critical pipes and pumps that move water and sewage around our towns and suburbs.
With an estimated value of $100 million, stage one of the Water and Sewer Upgrade Program has a four-year delivery timeframe and will include high priority projects in every corner of our region.
Check-in regularly and stay up to date with projects underway or coming soon. Or 'follow' this page for updates delivered directly to your inbox.
We're committed to ensuring our water and sewage network is not only meeting your needs today... but has the capacity and reliability to meet added demand from our growing population and withstand the challenges of a changing climate.
Our communities' water and sewer pipes and pumps may be out of sight, but keeping them in peak condition on your behalf is top of our mind.

This project adds to a legacy of water and sewerage infrastructure that was first created by leaders in our community during the goldrush.
When these visionaries built our early water and sewer networks, they did so to protect the health and wellbeing of locals, and to create the thriving cities and towns we live in now.
Our purpose remains the same today, to deliver services for public health and environmental benefit.
With more people in new suburbs, a growing number of infill residential developments, and the need to support economic development, industry, and jobs, it's critical we invest to replace ageing infrastructure and build new infrastructure to meet our future needs.
As a customer-funded business, we're investing wisely the money our customers pay us through their bills to future-proof the water and sewage networks we all rely on.
