Given that most of us leave the tap on whilst we brush our teeth and, given that the average tap running an average water pressure puts out five litres of water every minute and, that we spend two minutes on average (loving the averages today right) twice a day brushing or teeth, you could summise that the average person wastes say, 19 litres of water every day just brushing their teeth! Nothing like a but of guilt then to motivate one into doing somthing. Global bathroom manufacturer Roca have come up with this...the Intelligent Drain. Using a flow meter on the water pipes, information is cleverly sent to the drain cover's unique LCD display showing exactly how much water you've just used. Great if you either want to either conserve our resources or conserve your bank balance if you're on a water meter!
