WATER CYCLE

WATER CYCLE

1. EVAPORATION

   • Heat from the sun provides the energy for water to change from a liquid, like we drink, into a vapour. There is almost always water vapour in the air around us, but we can't see it. On a hot, sunny day water will evaporate faster than on a cold, cloudy day.

2. CONDENSATION

   • When water vapour cools, it condenses back into tiny droplets of liquid water
   • Precipitation
     • As more and more water droplets form, they will join together to from bigger water drops in the clouds. These drops become too heavy to stay in the air and will fall to earth as rain. If it is very cold, the water might freeze and fall as hail or snow. Any water that falls from the sky- rain, hail or snow-is called precipitation

3. MELBOURNE WATER CYCLE

   • RUNOFF
     • Some precipitation will soak into the ground or be taken up by plants but the rest will runoff into streams, rives, lakes and make it's way to the ocean.
   • COLLECTION
     • The water that comes out of your taps at home comes from rain that is captured and stored in a huge reservoir. There are no houses, farms or roads near the reservoir so our water is kept nice and clean and tastes great.
     • STORAGE
       • To make sure the water comes out of your taps nice and fast it travels from the catchment reservoir to a storage reservoir doser to Melbourne and then to one of 67 storage tanks in our area
       • USAGE
         • We use water for lots of things every day. A water meter at the front of your home measures the water going into your home. 
       • TREATMENT PLANT
         • Sewage leaves your home through drains or the toilet. It travels through pipes to the sewage treatment plant to be cleaned. Once the water is clean, it is recycled and delivered to some homes through purple pipes and taps for flushing toilets and waterning the garden, or it is realesed out into the ocean to join into the natural water cycle
