While attending EC1205 in Offenburg two weeks ago, I was demoing some of the Flukso site's features on Friday night. When looking at the hourly water chart, I noticed anomalous water usage at my home. The Fluksometer was reading a nearly constant water consumption of 11 liters per minute for over an hour already. Since our electricity consumption was near its base load, I figured my better half and the children were not at home. I then SMS'ed my wife asking her to check what was going on. Somewhat grudgingly she went home and noticed that one of the toilets hadn't properly terminated its flushing operation. In electricity terms, there was a short circuit between the water supply and the drain.
A quick calculation shows that this flushing incident caused a total of 1486 liters of water to flow down the literal and metaphorical toilet in a 2h15m time span. Money-wise this amounts to less than 4EUR. Nevertheless, this kind of needless waste bothers me.
Instead of haphazardly discovering these kind of leaks, we should have a monitoring system in place that performs a number of checks automatically. As a big bonus, it will not be me spoiling the party anymore, but rather an innocent bot!
Ironically, server-side threshold alerts have been running in alpha mode for quite a while now. The only thing that's still lacking is the configuration interface. I've bumped the priority of the feature to high. That should mean a beta in a couple of weeks time.
