Solar panels at the Eastern Treatment Plant

Melbourne Water is underway with a Request for Tender to develop a new solar farm at the Eastern Treatment Plant in Bangholme, helping to meet our goal of zero net carbon emissions by 2030.

The Eastern Treatment Plant was opened in 1975 to serve Melbourne's growing population. The plant sits on 1,100 hectares and treats about 330 million litres of sewage a day – about 40% of Melbourne’s total sewage.

The proposed solar farms are one initiative to help meet our ambitious emissions reduction goal, alongside other projects including hydro and biogas power stations and transitioning our car fleet to zero emissions vehicles.

Why this project is important

Melbourne Water is committed to reducing our net carbon emissions to zero by 2030. Establishing a new, onsite solar farm to help power the Eastern Treatment Plant is a practical way for us to cut our greenhouse gas emissions, and tackle climate change.

What’s happening and when

The solar farm is planned to be located close to our Eastern Treatment Plant and generate renewable electricity to help meet the plant's power needs.

To prepare the site for the farm, we completed works in early 2020 to fill a soil pit in the area immediately south of Thompson Road.

We will shortly be working through the tender application review process. The Request for Tender is also seeking tender applications for proposals to establish a second solar farm. Pending planning approval, the second farm is to be located at the Winneke Water Treatment Plant in Christmas Hills. Both solar farm projects are still in the design and planning stages and the tender application review process will assist with informing design details.


  • February 2019 – early  2020: Soil pit (solar site preparation) construction works, complete
  • May 2020: Request for Tender application process, complete
  • Mid–late 2020: Awarding contract
  • Late 2020: Solar farm construction to commence

More information

Melbourne Water will provide an update on the outcomes of the tender process when further information is available.
