This latest upgrade is required because strong population growth in the Gisborne area means the treatment plant is nearing its capacity for managing sewage inflows.

An upgrade will increase the plant’s capacity as well as improve the quality of recycled water produced, reducing its impact on the creek. The upgrade will also significantly reduce the plant’s energy consumption.

As the population continues to grow, we will need to manage the increased volumes of sewage to treat and the extra recycled water that is produced.

A major focus for Greater Western Water is identifying new users for this valuable local resource – including recreation spaces in new residential areas and suitable agricultural use. This has been identified in the integrated water management plan for the area which is being developed with the Macedon Ranges Shire Council.

In June 2020, Western Water’s Board confirmed the need for the Gisborne RWP upgrade as outlined in the project’s Business Case. From 1 July, 2021, the Greater Western Water Board will oversee the progress of this project.

We will now secure contractors and complete detailed design and construction for initial works on site to ensure it is ready for major works to take place. Early works will include removal of some sheds and a new access track to ensure the safety of staff and contractors, as well as repurposing an existing lagoon to manage storm flows. At the same time, we will undertake the assessments and planning required to complete the final design concept.

As we progress, we will keep the community informed and provide opportunities wherever possible so they can provide input on decisions that affect them. Early community values research will help us understand the priorities for consultation and inform detailed project planning.

Subject to final approvals, the main contract to design and build the plant upgrade will commence in late-2021.

Past upgrades

The most recent major upgrade to Gisborne RWP took place in 2012 when Western Water constructed the Gisborne Recycled Water Scheme, connecting agricultural customers in Gisborne South to Class B recycled water. This scheme provides farms with a reliable source of water – particularly during dry periods – and further reduces the volumes of recycled water for discharge.
