Transcript of LINDFIELD PUBLIC SCHOOL STAGE TWO TEAM Before we started the challenge, our group found out about...
We used a map of our school and a ‘key’ to
show the places in the school where drinking
water was usedWe highlighted the places in the school where water was used, by drawing a raindrop, as you can see on the next
slide…
It was quite tricky to figure out how to match areas of our school with their location on
the map! We persevered, and even went on an extra water walk one day when it was raining so
we could see any leaks or puddles
in our school.
- Staff toilets ?- Behind 4M (uncollected rainwater)
- Balcony (water lands on concrete below)- Staff taps ?
- Covered walkway (overflow of water from roof onto concrete)
- Pool itself- Old green pipes (cracks and leaks)
- Bubblers 1)People problems
- being left on!- water fights
2) Structural problems -overflow from poor drainage
- bubblers that won't switch off
From our water
walk and graph, we came up with this
list…
- Staff toilets ?- Behind 4M (uncollected rainwater)
- Balcony (water lands on concrete below)- Staff taps ?
- Covered walkway (overflow of water from roof onto concrete)- Pool itself
- Old green pipes (cracks and leaks)- Bubblers
1)People problems - being left on!- water fights
2) Structural problems -overflow from poor drainage
- bubblers that won't switch off
Specifically, we decided to focus on one particular
bubbler trough, which is located near the Grade Three and Four Classrooms at our
school.
Why we decided to create a design for this
particular site:
Why we decided to create a design for this
particular site:• We could see there were several
problems here.• The problems were not too big – so we
knew we could do something about them.
• The amount of drinking water being wasted was higher than in other areas.
A closer look at the ground next to the bubbler trough
It looks like the water isn’t
going down the drain properly!
The water seems to be hitting the edge of the pipe and a lot of it is
splashing out and onto the concrete. What a
waste!
We also thought it would be a good idea to find out if we could replace some of the old bubblers with new
ones as the old ones are REALLY hard to turn off and often leak…as you can
see in our next picture.
Hi Andrew, We are a group of eight Year Three and Four students, taking part in a Sydney Water saving challenge, called Kids' Design Challenge. We have been asked to identify a part of our school where water is being wasted. We have to design and model a solution to this problem. We identified the bubblers used by Years Three to Six as our major problem. (See attached Images 1 & 8). We would like to discuss our ideas with an expert in the field, which is you! There are two main problems with these bubblers. The first problem is that many of the bubblers don't turn off properly, or are very difficult to turn off. (See Image 4) This leads to a lot of water constantly running out of the trough, even when there is no one using the bubblers. (See Image 5) We are planning to ask our SRC to buy us new bubblers that turn off automatically. Only one out of the ten bubblers in the trough is currently automatic. (See Image 9) Would you be able to provide us with an estimated cost of new automatic bubblers please? The second problem is that when the water runs out of the trough it does not go completely into the drain. A lot of water hits the side of the drain and splashes onto the concrete. (See Image 3) Can you suggest any ideas to solve this problem? Thank you very much, Andrew. We really appreciate your assistance. Regards, Lindfield Public School, Kids' Design Challenge Team
Not only did we email Andrew, our local plumber, but we also got in
contact with our School Representative Counsel, who we heard were trying to figure out a
way to replace the faulty bubblers in our school.
Our KDC team drew up a diagram for the SRC, indicating which bubblers were
of highest priority for replacing, in the particular bubbler trough we were hoping
to improve.
Why we decided on this particular design
Just from looking at the site, we could see that some additional pipe could help fix the leak. Simple, but
logical!
Our local plumber called us after receiving our email. He agreed with our idea, and even suggested that a copper
pipe would be the best material to use. He is going to come to our school and show our team just how to fix
the leak!
How the proposed changes will meet the user’s needs and save drinking water:
There won’t be wet slippery, mossy ground next to the bubblers anymore, and this water
won’t just fall on the concrete, where it is completely wasted
Some of the bubblers will be easier to turn off, which means that they won’t be left
running, and more drinking water will be saved
Did you know? A dripping bubbler can waste more than 2000 litres a month. That is 24,000 litres a year!
Thanks for watching and listening to our presentation. We hope you have
learned a bit more about saving drinking water. We certainly learned
a lot and hope that you have enjoyed hearing about our KDC experience as
much we enjoying having it!!
