depends on the system your looking to implement.
If you want a fully automated system with proactive daily reports on water usage and leak detection, our average cost is anywhere from $350-$450 per site: That includes install and insulation and all the reading equipment required.
Something more simple like a touch read system with the touch pad on the side of each home, that could run you anywhere from $300-$400 per site. That includes install and insulation and all the reading equipment required.
You looking at even cheaper rates if you put the meters in your self.
These are just ranged estimates with more info i can get you a hard quote..
