Sure. The electric and water meters used by the city I live in are by a company called Elster. They use the name EnergyAxis or EA_LAN to describe the mesh network. Either of those should return hours of reading material on a Google search. The short version is that each electric meter communicates on the ISM 915MHz band using the Texas Instruments CC11xx chip, and relays messages from meter to meter until it reaches the "gatekeeper", which is tied to a WAN and to the city's infrastructure.
