Western Treatment Plant tours

Visiting the Western Treatment Plant is a great way to learn first-hand how the plant works and experience the scale and environmental importance of the site.​

Changes to education tours in 2019

We have now relocated our upgraded administration building to the historic town of Cocoroc. However, for the time being, Education Tours will still use the Discovery Centre with access via Exploration Avenue off Geelong Road/Princes Highway, between New Farm Road and Newmarket Road.  

Once the new education buildings are completed, access will be via William Thwaites Drive and Metropolitan Farm Road. We will work closely with schools booked in for tours in the latter half of 2019 to ensure the tours meet your needs.

Changes to Education tours in 2020: No tours will be held in Term 1 of 2020 (January - April), we will work closely with visitors to ensure that tours meet your needs after Term 1. 

Book your visit

Weekday visits to the Western Treatment Plant are available to school, tertiary and community groups by pre-booking on available dates. If you need help booking, call us on 131 722.

Tours will be cancelled on Total Fire Ban days and Extreme or Code Red Fire Danger ratings.

Members of the public can tour the site during one of our regular open days.

A virtual tour is coming in 2019

A virtual tour of the Western Treatment Plant will be available in late 2019. The tool has been created in line with the curriculum and will let you visit WTP without even leaving your home or classroom!

Student supervision and discipline is the school's responsibility, and teachers and adults accompanying school groups should actively supervise students at all times. Students should not be unsupervised at any time.

We reserve the right to cancel a booked tour, and ask individuals or groups to leave the site immediately if any action or behaviour is unsafe.

Education activities

Make your visit to the Western Treatment Plant even more exciting and educational with our activities for students to complete before, during and after their visit.

Teacher activities – before and after visiting

Our Melbourne's Water Story website hosts a variety of resources that teachers can complete with their students before and after visiting the plant. These include hands-on investigations and discussions, enhancing students' tour experiences and supporting units of work around wastewater treatment.

Tour activities – during the visit

School groups can participate in up to three education activities, which are run by our education officers at the plant.

Activities must be nominated at the time of booking, and additional costs apply for each activity per student.

Discovery Centre guided tour (years 3–12)

Where does our drinking water come from? What goes on beneath our city? How is water recycled? Take a guided tour of the water cycle story from the catchments to the coast and learn how we're helping to create a sustainable future.

Living in a catchment (years 5–10)

What is a catchment? What's in a catchment? What are the differences between the upper, middle and lower regions of a catchment? Students work in teams to construct a giant jigsaw puzzle to study the factors that affect water quality.

Stormwater story (years 3–6)

How does litter and rubbish end up in our rivers and creeks? Students act out a journey down the Yarra River from catchment to coast to see how humans impact stormwater quality.


Water smart city (years 3–10)

Explore stormwater and pollution in the Lego city! Students are introduced to the impacts of stormwater on our waterways and bays. Working with the model, students address stormwater issues and adapt the city to make it water smart.

Water recycling model (years 5–10)

This model helps students better understand where our water comes from and the ways that recycled water can be used in horticulture, agriculture, industry and recreation. Real water flows over the model's catchment landscape with sound effects and track lighting showing different features of the model in action.

Wetland food chain game (years 3–6)

What happens to our food chain when there are too many predators? Students find out through this interactive game, which illustrates the food cycle and energy transfer in our special wetland environments. The game demonstrates the effects of pollution and predators on the transfer of energy between trophic levels.

What goes where? (years 3–7)

Where should household wastes go? What can go onto the compost heap, the recycling bin or the trash? What should go into the sewerage and stormwater systems? In this interactive game, student teams actively debate the answer to these questions.

Micro-organisms at work (years 7–9)

Discover the micro-organisms that play an important role in the biological treatment of wastewater at the Western Treatment Plant. Learn about how different environments in the treatment process are managed to encourage different micro-organisms to go to work. 

Discovery Centre

The Water Discovery Centre brings the water cycle to life for visitors through engaging displays. Visitors can interact with the displays to learn more about:
