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:

would need to be purchased. This was considered a very expensive
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.

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:
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.
