What Mesa's Water Means for Your Home

  • Know your zoneEast and south Mesa run harder than the City Zone, so the same softener can be right-sized in one neighborhood and undersized in another. We size to your address.
  • Hardness changes with the seasonWhen the mix shifts toward groundwater, hardness goes up. A metered softener adjusts to the water you actually use instead of running on a fixed timer.
  • Chlorine tasteMesa's water is chlorinated. A whole-home carbon filter takes out the chlorine taste and smell at every tap and protects the softener resin.
