We use water every day, but we don’t often stop to think where it's from or where it goes! Take a journey with us to follow your water, from the clouds, to your taps, to a sewage treatment plant.

Key terms to remember
Evaporation - The sun heats the water in our oceans, lakes and rivers changing it from a liquid to a gas. The water vapour rises into the sky.
Transpiration - Plants take up water from the soil with their roots. They release some water into the air as water vapour through small holes in their leaves.
Condensation - Water vapour cools when it is high in the sky and turns back into liquid as tiny water droplets forming clouds.
Precipitation - Water falls from the clouds back to the earth as rain, snow, sleet or hail.
Run-off – Water flowing off the land into rivers and streams.
Infiltration - Water soaks into the soil.
Groundwater - Water found underground in the cracks and spaces in soil, sand and rock.
The Natural Water Cycle
Water evaporates from the oceans and waterways by the sun’s heat.
The sun’s heat causes the water to change into gas and rise into the air (evaporation).
The gas begins to cool when it is high in the sky and turns back into a liquid as tiny water droplets form clouds (condensation).
The clouds become heavy and the water falls from the sky as rain, sleet, hail or snow (precipitation).
The water that falls to the earth can run off into waterways, or absorb into the ground (infiltration) where it may sink deeper into aquifers and underground water pockets (percolation) that exist naturally below the surface of the earth.
The cycle begins again.
Did you know...
In our region, the water falls from the sky into dams. The water is treated at a water treatment plant managed by Seqwater.
The clean water is pumped underground to a Unitywater reservoir.
Key terms to remember
Dam - A large wall or barrier that stops the flow of water, forming a reservoir or a lake.
Water Treatment Plant - A facility that takes fresh water from the environment and cleans it so it is safe for humans to drink.
Reservoir - A large dam or storage facility that stores water.
Art meets water storage
Who would have thought a reservoir or water tower could be beautiful? Unitywater works with local communities to paint artworks on their water reservoirs and towers. Explore the videos below and see if you recognise one you've seen near your school or home.
Did you know?
Putting the wrong things down your sinks, drains and toilets can cause all sorts of problems in your home and impacts on the sewerage network. It can:
• block or damage your home’s sewer pipes
• cause problems at the sewage treatment plant
• harm the environment and health of our waterways.
Unitywater is responsible for removing and treating your sewage. Your sewage flows through underground pipes from your house to a Unitywater sewage treatment plant.
Did you know?
Sewage doesn’t just disappear when you flush the toilet or drain the sink. It must be treated or cleaned before we can return it to the environment.
Unitywater is responsible for removing and treating your sewage. Your sewage flows through underground pipes from your house to a Unitywater sewage treatment plant.
Stormwater
Storm water that runs off roads and roofs is collected in storm water drains. It travels through pipes to waterways.
Think at the sink
Putting the wrong things down your sinks and drains can block and damage your pipes, causing sewage overflows in your home.
It also impacts our sewerage network. It causes blockages and overflows at our sewage treatment plants.
Please do not put these nasties down the sink or drain:
• Fats, oils or grease (from the kitchen or car)
• Solvents, paint and turpentine
• Chemicals, herbicides and pesticides
• Plastics including food wrappers and apple stickers
• Food scraps including egg shells, bones and cooked rice
• Dairy products
• Coffee grounds
Key terms to remember
Pump Station - A facility that pumps water from one place to another. A pump station transports the clean water to your house, and the sewage to the treatment plant.
Sewage - All the used water that goes down our sinks, out of the shower, from our washing machines and toilets.
Sewage Treatment Plant - A facility that cleans sewage so that it is safe to return to the environment.
Treated effluent - Water that has been cleaned at a sewage treatment plant.
The Sewerage Network
The sewerage pipes, pumping stations and sewage treatment plants are part of the sewerage network.
What is sewage?
More than 99% of sewage is just water. The remaining 1% contains:
• Micro-organisms such as bacteria, viruses and protozoa.
• Nutrients such as nitrogen and phosphorus.
• Solids such as dirt and other large items.
These nutrients can cause disease and harm our environment. This is why Unitywater’s sewage treatment process is so important. The sewage is treated at a sewage treatment plant to remove these harmful elements.
Look around you and you will see so many things made from plastic, but all this plastic is starting to really impact our environment and wildlife.
Did you know Australians drink 726 million litres of bottled water every year - and only 18% of the plastic water bottles are recycled.
The rest ends up as landfill or as litter. Plastic drink bottles have been found to make up 40% of the litter in our environment.
Take a journey with us to see what really happens to a single use water bottle.
The global issue of plastic waste can seem overwhelming. But one very easy way to make a difference locally is to swap single use plastic water bottles for reusable bottles.
Reusable bottles can be filled with tap water over and over again, so you can easily cut down on the amount of single-use plastic in your world with this one simple change.
Take a journey with Brittany and Tim Silverwood of War on Waste and Take 3 for the Sea to find out about the impact of single-use plastic and why it’s important to get back to tap!
Follow Tim and Brittany as they explore one of the easiest ways to reduce your plastic waste - swapping single-use water bottles for reusable bottles filled with tap water.

Friend of Sludge
You know what's what at the bioreactor.
Good choice!
Plastic is not so fantastic. Back to Tap is the way to go.
