About this project

A major and innovative upgrade to Wodonga's wastewater treatment plant is now underway to increase its capacity and reduce carbon emissions.

This $74 million project will lead to the more efficient and effective reuse of waste to create renewable energy that can be used 'behind the meter' to power the plant, or fed into the electricity grid.

The upgrade has been designed to unlock circular economy opportunities, including the production of biogas, recycled water, heat and biochar, with future potential to create slow-release fertiliser for agriculture.

Wodonga Resource Recovery Hub

Our Wodonga Resource Recovery Hub is transforming wastewater treatment into a source of renewable energy and valuable resources.

A three-megawatt solar farm alongside the Wodonga Wastewater Treatment Plant generates enough electricity to power the plant during daylight hours. Excess energy is fed back into the grid, helping offset electricity use at other North East Water sites. Combined with the recent wastewater treatment plant upgrade, the treatment plant's Scope 1 and Scope 2 emissions will reduce by 88% — from 12,124 tonnes to around 1,500 tonnes each year.

The Hub is also unlocking the value of resources produced onsite, including biogas, recycled water, heat and biochar.

In partnership with Australian Gas Infrastructure Group, North East Water is looking at converting biogas into renewable biomethane for the local gas network. This will create new revenue opportunities while helping local industry reduce carbon emissions.

We are also exploring opportunities to supply recycled water and biomethane to local industries, and working with councils, Landcare groups, agricultural partners and industry to source organic materials that support increased biogas generation and biochar production.

Together, these initiatives are well on the way to creating one of Australia's leading circular economy precincts, turning everyday wastewater into renewable energy, valuable resources and environmental benefits for the region.
