Stop that drip

In a water audit the grade 7 learners discovered that they had a leaky jojo tank tap. When we did the culculations, the tap leak was losing 500ml of water in half a minute. We worked out that in 7 days the 10 000 l  jojo tank would have been emptied. Fortunately the school hired a local plumber to fix the leaky tap thus saving 10 000 litres. This is a wonderful example of how online challenges make a difference in real life. Incredibly water saving worth,lots of bonus points and good karma.
