Today the Water Explorers team went on a ‘Flushed Away’ water saving mission for Precious Water. We had to use lots of our maths skills. The team scoured the school counting the number of toilets, sinks and showers. They checked for leaks and to see if the toilets had a dual or single flush. They even remembered to count the staff facilities and school kitchens.
The school has 27 toilets only 8 of which have a dual flush. There are 38 sinks and 19 showers. There were 5 leaks, mainly in the girls’ showers, which they have reported to the caretaker. We’ve also asked if we can put full bottles of water in the cisterns to reduce each flush.
We have 380 staff and students. Most students seem to go to the toilet between 1-2 times – so an average of 1.5 times a day. If each flush is 10 litres then the school uses 5700 litres of drinking water each day just to flush the toilet. We use even more when you consider about 1 litre is used to wash our hands and lots of water is used for cooking and washing up in the kitchen. We estimated that every day the school uses more than 10,000 litres – which is an amazing 10 tonnes of water. If that’s our school imagine how much the whole of Corbridge uses!
To make sure everyone knows that they should save water we made loads of small posters (using scrap paper of course) and put them up in the toilet blocks, next to the sinks and near the showers.
The team were surprised how much they loved the mathematical, water-saving mission!
