Greenhouse Gas Reduction

Western Water has pledged to reduce its greenhouse gas emissions by 10% (of the average emissions from 2011-2016) by 2025.

Western Water uses electricity to treat and distribute drinking water and sewage across our service region.

With strong population growth in the region, our pledge will almost halve our future emissions compared with continuing to provide services the way we did in the past.

How will we meet the pledge?

  • Installing large solar panel systems at treatment plants
  • Generating more low-carbon electricity from our biogas cogeneration plant, including exploring processing of food waste to extract biogas
  • Exploring replacement of diesel pumps with solar panels and batteries. 

Biogas Cogeneration Facility

Constructed in 2011, this $2 million facility captures methane emissions from the sewage treatment process to produce 100% renewable electricity.

The biogas cogeneration facility is located at Melton’s recycled water plant.

Food Waste to Energy Project

The digestion process used to treat sewage can also treat food and other organic wastes.

We are developing a business case to use the soon to be decommissioned anaerobic digester at Melton RWP for this purpose, generating more renewable energy. At the same time, we will reduce the amount of local food waste going to landfill.

Interested food and other organic waste producers and/or contractors can find out more by contacting our Renewable Resources team on 9218 5400.
