Wastewater education

Don't flush and forget, let's change our mindset.​

Everything that is put down the drain or flushed down the toilet requires transport through our hundreds of kilometres of underground pipes and over 140 pumping stations, as well as treatment at our wastewater treatment plant in Pukete.

Did you know in the past 12 months, there have been approximately 380 wastewater blockages within the city's wastewater network and around 180 wastewater pump station call-outs due to foreign items causing blockages?

Blockages can create wastewater overflows and damage to the wastewater network, which can cause pollution of the environment. By disposing of everyday items correctly to rubbish, we can help to prevent blockages and protect our environment.

Here is a build-up of non-biodegradable items on one of the protective screens at the wastewater treatment plant:

Let's break it down – if it's not pee, poo or paper, put it in the bin!​

Some everyday items that should not enter the wastewater network are: 

  • Wet wipes/cleaning wipes
  • Nappies
  • Sanitary items
  • Cotton buds
  • Oils and greases
  • Rubbish
  • Hygiene products
  • Cleaning products/chemicals/paints
  • Food scraps
  • Paper and plastics
  • Paint rinse water

Wet wipes and cleaning wipes are a significant contributor to blockages. They contain plastic fibre which can clog up pipes and pumps fundamental to the operation of our wastewater treatment plant and network.​

Wastewater treatment plant tours

Hamilton City Council conducts tours at our wastewater treatment plant for interested groups of people. The tour will explain the water treatment processes and provide a general overview of Hamilton’s water supply. 

Tours are tailored to the audience and are intended for:

  • General public
  • School groups (Year 5 and above)
  • Special interest groups

PLEASE NOTE: Currently maintenance and upgrade work is being undertaken at our treatment plant. The work can impact on access to a number of areas of the plant and may require us to restrict some tours and public visits to the site until the majority of works are complete. The restrictions are required to ensure work can be carried out efficiently and in a safe manner. We look forward to resuming tours again as soon as possible.

Tours can be arranged by completing the online registration form. ​

Alternatively, please ring City Waters on (07) 838 6999.​​
