Barwon Water is partnering with major businesses and local councils on two Renewable Organics Network (RON). These projects will leverage existing water and sewerage infrastructure to reduce the organic waste that currently goes to landfill, create clean renewable energy, reduce costs, generate jobs and drive economic growth in the region.

Involved alongside Barwon Water are the five councils within the G21 region - City of Greater Geelong, Surf Coast Shire, Colac Otway Shire, Borough of Queenscliffe and Golden Plains Shire – as well as neighbouring Wyndham City Council and major export manufacturers.

This Australian-first project in Colac aims to not only convert organic municipal, commercial and sewerage waste to dispatchable renewable energy but also recycle the waste into value add by-products such as soil enhancers for agricultural purposes.

    In an Australian first, Barwon Water is partnering with two major Australian exporters to deliver the Colac Renewable Energy Network (formerly known as Colac WEB).

    Construction is currently underway at the Colac Water Reclamation Plant to enable acceptance of higher-strength organic waste from the Australian Lamb Company (ALC) and Bulla Dairy Foods, and the subsequent production of electricity and hot water via biogas cogeneration technology.

    Construction of the facility is scheduled for completion by the end of 2022, with the cogen installation completed by December 2020.

    Benefits of the Colac Renewable Organics Network include:

    • For the manufacturers, the Colac Renewable Energy Network creates a circular economy, where waste production generates savings on electricity and heating bills and reduces their carbon emissions.
    • For Barwon Water customers, the energy created can be used to power (and reduce intensive energy costs for) the Colac Water Reclamation Plant, keeping our bills affordable.
