When you turn on the faucet in Mesa, you can be assured of safe, clean drinking water.  Mesa relies on three sources of drinking water: Salt and Verde River water from the Salt River Project; Colorado River water from the Central Arizona Project; and groundwater from 32 City wells.


Mesa's wastewater is collected through many miles of sewer lines and treated at one of three water reclamation plants.  These facilities use various processes to achieve Class A+ standards for reclaimed water.  Reclaimed water can then be used on golf courses, as crop irrigation, recharged back into the ground, or discharged to natural waterways.  

Service Area

The Eastern Canal is the dividing line between the Mesa's two major water service areas. The canal runs diagonally southeast through Mesa from Gilbert and McDowell roads to Greenfield and Baseline roads.
