Many of you may have heard about the goings-on around the widespread installation of smart energy meters in California (after all, there have been lawsuits, legislative hearings, and mandated independent meter testing, just for the Pacific Gas and Electric meter installations).

So why go through all that to install smart energy meters? Because they hold huge promise for helping consumers reduce their energy use and for adding flexibility and reliability to how the grid is managed.

What you may not have heard as much about is that smart water meters are also being installed – more than half of California water utilities have some smart meters in their districts (via the New York Times). Ideally, smart water meters would provide real-time (or near real-time) feedback on water use to both the water utility and the consumer.

Also, Oracle has apparently developed an interest in smart water meters as a potential future market, as they already sell software systems to water (and power) utilities (via GreenTechmedia).
