The electricity authorities are starting to get it right with smart meters, and now websites that allow you to monitor your smart meter and keep tabs on how much electricity your house is chewing through. Apparently just being able to observe power use has resulted in savings of 25% in houses where monitored smart metering is in use.
So why is the water authority lagging, where are the smart water meters? Such a meter would either communicate back to the water authority as do smart meters, and customers access their meters on the internet, or else they could send a data stream back to the household.
And I reckon a display in the bathroom, of liters/minute, and a mounting toll of cents' worth of water used, would probably encourage people to shower smarter and use less water. Similarly, another display in the kitchen and/or laundry would go a long way towards reducing water wasting in those areas.
So roll on the Liter Meter!
