Mesa Water prepares year-round to provide clean, safe and reliable water during severe weather, power outages and other emergencies.

Our preparedness efforts include maintaining emergency backup power and monitoring water facilities through Mesa Water’s state-of-the-art Supervisory Control and Data Acquisition (SCADA) system, which can detect loss of power. These tools support reliable water delivery throughout our service area.
