Project Overview

We're upgrading the Gisborne Recycled Water Plant to better meet the needs of the growing community in Gisborne and the surrounding area.

As the population continues to grow, we need to manage the increased volumes of sewage to treat. We’re meeting this challenge by investing in the Gisborne Recycled Water Plant upgrade to ensure we can manage the community's increasing volumes of wastewater by turning it into fit-for-purpose recycled water for a variety of uses in the region.

The upgrade involves constructing a new treatment facility at the existing site, which will allow Greater Western Water to:

  • meet demand from the growing population with increased capacity,
  • produce higher quality recycled water,
  • reduce noise and odour, and
  • use 40% less energy compared to the existing facility when at full capacity.

The plant currently has the capacity to treat close to 2 million litres per day. When the upgrade is completed, this will increase to 3.65 million litres per day.

The upgrade will benefit all existing and future customers and improve the health of our waterways by using the latest technology to improve how wastewater is treated.

The Gisborne Recycled Water Plant treats sewage from Gisborne, New Gisborne, Macedon and Mount Macedon. It produces Class B recycled water which is then used locally for agriculture and recreation irrigation. The remainder is released into Jackson’s Creek under an EPA Victoria licence.

Wastewater management is an essential service to the community and our recycled water plants are a vital community asset.

The Gisborne Recycled Water Plant is one of eight recycled water plants owned by Greater Western Water. Since it was first constructed in the 1980s, it has undergone a series of upgrades to improve its capacity and performance.

As the population continues to grow, we will need to manage the increased volumes of sewage to treat. We are exploring new and greater productive uses for recycled water in our service region.

Next steps

We’ll continue to engage with stakeholders (including Council, Government, EPA, waterways and environment groups and traditional owners) and local residents to ensure the upgrade delivers the best outcomes for the community and environment.

We’ll continue to keep you updated as the project develops.
