California is in a drought right now and water is expensive, so monitoring water use seems like a good idea. Over the last (mumble) years we have had pipes break a couple times and major amounts of water were expended, which is quite expensive and irresponsible ... another reason to monitor continuously.

Water use is automated using EKM Metering devices: water meter, pulse counter, and serial-to-ethernet converter. The simple software 'glue' I wrote to make the water data visible (coded in C and Python and using xml) is Linux/Unix centric and will require extra effort to use it on some other OS. See ekmexample-2014-10-19.tar.gz , a 15KByte gzip tar file containing the source code.
Rainfall is monitored with a simple plastic collector ($2USD at a local hardware store) graduated in inches. Recorded & emptied each morning.

June 21-29, 2015 we had a 25-year-old plastic water pipe break underground. Estimate of leak: 4K gallons. Should have noticed before the 29th, but we were too busy. July 1 I implemented an automatic email to ourselves in case water use exceeds expectations.
