Does your school need water?
A well fertilized sports field could lose up to 5mm of water per day through evapotranspiration in the hotter months. Given a spell with no rain for two weeks the total loss would amount to a water deficit of around 70mm. This represents close to 500, 000 litres of water for a rugby or soccer field. If we cost water at R28.32 per 1,000l, the estimated cost over two weeks for the rugby/soccer field would amount to R14,160.00 or R84,960 per year
