From the City of Bellaire:

AquaHawk Alerting is a FREE service for the City of Bellaire customers that will assist you in efficiently managing your water usage and potentially lowering your monthly bills.  You will gain a better understanding of how you’re using water and learn effective ways to reduce water usage and save money.  AquaHawk Alerting will be available later this month.  Be sure to check the City website for information on how to register once the program is live.
