Almost no difference in water consumption patterns between 2 time periods – WHY?
Possible Reasons: Decrease – ‘Novelty effect’? Steady rate – Restricted showering times anyway Increase – 21CIS Sports Festival Increase – Hotter outdoor temperatures Increase/Steady rate – Cultural habits
Other sources tapping water: toilets, sinks, sprinklers, etc.
