On average they say we use approximately 148 litres per person per day through bathing, cleaning, toilets and consumption and this is ever increasing. Focusing on the school environment and toilets alone we take an example.
A Primary School, with an average of 150 pupils and 6 staff where each person would visit the bathroom once taking lowest option of toilet cistern system (6 litres): That would account for nearly 950 litres per day before any other water usage consideration.
Rainwater harvesting is a simple solution to the now increasing price of water which our schools are only realising from the Water Framework Directive. This alternative water source can reduce costs of mains water as the bulk of water used in schools is for toilet flushing.
