Plumbing & Water Treatment
in Glendale, AZ

Glendale draws from the same two river systems as the rest of the Valley — SRP’s Salt and Verde supply plus CAP Colorado River water, with limited groundwater — and its water services page reports more than 19,000 quality samples a year. One distinctive detail: Glendale’s primary disinfectant is chlorine dioxide rather than plain chlorine. It does the same public-health job with a different byproduct chemistry (chlorite instead of elevated TTHMs), and activated carbon filtration handles the taste-and-odor side of either approach at every tap in the house.

The arsenic picture stays as the treatment plants report it — averages of 3.1 ppb (Jensen) and 1.6 ppb (Glendale plant), well under the 10 ppb federal limit — and the hardness is classic Valley: hard enough that softening is the difference between scrubbing scale and not. When the city posts its next annual report we’ll read it the same way we read this one — numbers first.
