We were very enthusiastic about this challenge and happy to learn ways to save water and collect rain water. We found it fascinating to explore countries with different rainfall patterns. We plotted these on a map. We went on a tour of the school to look at all the rain water tanks (nine in all of different sizes) that the school has already installed and realised that the school could get more. Four pupils in our class had water tanks at home. We have 4 X 10 00 litre, 3 X 100 litre and 2 X 5 000 litre tanks at school. The average capacity of our water tanks is 5 888 litres. The total rainwater that can be harvested in these tanks is 40 800 litres. One of the rainwater tanks is linked to one of our bathrooms to supply water to the toilet and basins. The others get used to water the schools gardens and vegetable garden.
