What This Means For You
At 15 grains per gallon (GPG), Scottsdale has very hard water—similar to neighboring Phoenix. Scottsdale operates its own independent water utility with some of the strictest water softener regulations in Arizona.
Scottsdale Water operates independently from Phoenix, blending surface water from the Salt River Project and Central Arizona Project with local groundwater wells. The city has implemented aggressive water conservation measures, including restrictions on certain types of water softeners to protect reclaimed water quality.
Important: If you're considering a water softener in Scottsdale, you must use a demand-initiated (DIR) unit—time-clock softeners are prohibited. Check for available rebates before purchasing.
