Things to know before you go

Changes to education tours

Cocoroc township at Western Treatment Plant site
The historic town of Cocoroc.

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 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, 2020 (January-April). We will work with visitors to ensure that tours meet your needs after Term 1. 


We are committed to the safety of all visitors to our sites. When visiting our tour sites, we ask that you strictly follow these safety rules at all times:

  • wear closed-toe, flat-soled shoes – sandals and thongs are not permitted on site
  • wear long pants/trousers
  • stay with your tour guide at all times while on tour
  • do not climb on or over railings
  • do not touch any machinery or equipment

The Western Treatment Plant treats sewage, which contains many micro-organisms including bacteria, viruses and parasites. When visiting the plant:

  • avoid contact with sewage and sewage-related products
  • wash your hands before leaving the plant or eating
  • do not eat or drink during the tour
  • wash any contaminated clothing separately to your normal washing
  • cover any open wounds, and report any minor cuts or abrasions that occur while onsite to Melbourne Water
  • wear appropriate clothing for all weather conditions as activities are conducted outdoors

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.
