Our inquiry learning question for Term 4 is:
Where does our water come from?
We found the answer when we went to West Barwon Reservoir in the Otway Ranges last week.
Here is the ‘information report’ from our day.
The Geelong Water Supply comes from West Barwon Reservoir.
The Otway Ranges are close to the southern coastline near Lorne.
It rains alot high up in the mountains and the rainoff from the mountains form two rivers-
Munday Creek and West Barwon River.
When Geelong was settled and required a continuous clean water supply, it was decided that a huge wall would be constructed where the rivers met.
A huge reservoir now exists with the mountains surrounding and a reliable supply of rain falling in the catchment area.
The reservoir is presently near capacity- 97% full.
During the drought years the levels fell below 25% and LLPS students saw a very different reservoir to the huge reservoir of water today.
The water is channelled down to Wurdee Boluc were it is treated. The treatment plant is down the mountains so the open channels flow due to gravity.
The process gives us pure, clean drinking water through a network of pipes that range from huge pipes that adults can stand inside to the little pipes that lead to your kitchen tap.
Once water is used in your home it becomes waste water. It goes down your drain on another journey to keep our lives healthy, clean and safe.
Our message is to never take our water supply for granted.
Water is precious- more precious that gold!
