Gisborne Recycled Water Plant Upgrade

We’ve been progressing the design for the Gisborne Recycled Water Plant following approval of the Business Case in late 2020.

As we prepare the new Greater Western Water website, this page will soon be archived.

For all the latest news and to register for updates, please visit our new interactive Gisborne Recycled Water Plant upgrade YourSay GWW page.

Greater Western Water has improved the design and enhanced the treatment process for the Gisborne RWP Upgrade. This will result in further improvements to the quality of the recycled water the plant will produce.


The plant treats sewage from Gisborne, New Gisborne, Macedon and Mount Macedon. The upgrade will allow Greater Western Water to meet demand from the growing population, improve recycled water quality & reduce energy consumption.
