Update - June 2019

Preliminary site works have been completed. The tender process for the major construction contract is currently under way.

Update - February 2019

Preliminary construction work on the site will commence in coming weeks. For more information read our fact sheet on construction.

Update – November 2018

We have submitted our works approval to the EPA. For more information about the process, please visit the EPA website.

Update – August 2018

We have received all Essential Services Commission and government approvals. The initial design is complete and detailed design is underway. The EPA has provided us with initial advice and we will be submitting our EPA Works Approval over the coming months.

Why are we upgrading the Drouin Wastewater Treatment Plant?

Drouin’s population is growing rapidly and this means we need to expand the capacity of the existing wastewater (sewage) treatment plant to meet the town’s needs.

After weighing up environmental, technical, social and economic factors, Gippsland Water assessed that the best course of action is to build a new mechanical treatment plant on the existing site on Settlement Road.

Which type of treatment plant?

Different options were considered for treating Drouin’s wastewater including:

  • Having a variety of satellite wastewater treatment plants around Drouin;
  • Keeping a single, central Drouin wastewater treatment plant (which would require the existing treatment plant to be upgraded); and
  • A single treatment plant for both Warragul and Drouin.

After studying the options available, the lowest-cost option for customers was to maintain a single, central treatment plant for Drouin and undertake a major upgrade at that facility.

We then looked at different options to establish the best outcome for Drouin’s future.

These included:

  • Constructing additional lagoons; and
  • Constructing a mechanical treatment plant.

There is no room for additional lagoons on the existing site: additional land would need to be purchased. This was considered a very expensive option.

Alternatively, a mechanical treatment plant can be constructed on the same site and is much more cost effective than constructing additional lagoons.

It also provides higher quality treated wastewater for reuse or returning to the environment.

Building a new mechanical plant offers the best value to Gippsland Water customers and the community.

This new mechanical plant will work together with the existing lagoon system to produce wastewater that is suitable for returning to the environment.

What are the community and environmental benefits?

The upgrade will ensure a more flexible and robust wastewater treatment facility that delivers sustainable and affordable wastewater treatment to the residents of Drouin.

Improving the reliability of the plant has several community and environmental benefits:

  • Cleaner wastewater means less odour for nearby residents and better protection of public health.
  • The treated water released from the new treatment plant will be of higher quality, therefore protecting the ecology of local waterways and Westernport Bay.
  • Producing high quality treated wastewater could allow us to recycle more wastewater for irrigation.

Solar panels will be installed onsite to help run the plant.

How long will this take?

We expect the construction phase of this project to take up to two years, preliminary works began in early 2019. The major construction phase will begin in early 2020.

We will keep the community informed throughout the process.
