Plumbers in Scottsdale, AZ

Most homes in the city get their water from Scottsdale Water, the City's utility. Its 2026 water quality report says Colorado River water, carried by the Central Arizona Project canal to a treatment plant at the Water Campus, made up 71% of the 2025 supply. Salt and Verde River water from the Salt River Project added 13%, and groundwater added 8%; the City has 21 active wells. Its Salt River Project supply can be used only on land south of the Arizona Canal, and a home may get one source or a blend, depending on season, weather and demand.

There are exceptions inside the city limits. A City report adopted in July 2021 lists two built-out areas served by EPCOR Water, a private company: about one square mile west of the Arizona Canal between Jackrabbit Road and Indian Bend Road, and an area near the Fountain Hills boundary. If your bill comes from EPCOR, the City's hardness and water quality figures do not describe your water. Check the name on your water bill first, then use that supplier's report when you plan a softener or filter.

The median Scottsdale home was built in 1991, according to Census estimates. Of roughly 139,800 homes and apartments, about 48% were built before 1990, 37% between 1990 and 2009 and the rest since 2010, and about 65% of occupied homes are lived in by their owners. In an older house, original supply lines, drain lines and fixtures are more likely to come up during a repair, so it helps to know what has already been replaced and when.

Age also matters for pressure. A pressure regulating valve has been required on all new buildings since 1995, according to the City's water utility. For older buildings where pressure stays at 80 psi or higher, the City encourages having a licensed plumber install one, and it notes that regulators can stick open or closed over time. The City adds that a licensed plumber can evaluate the valve; Trident works under Arizona Registrar of Contractors license ROC 331536.

The City's home improvement guidance lists many everyday plumbing jobs as Minimum Plumbing Permit work: replacing a water heater, replacing water lines in a single-family home, repairing broken water lines, plumbing for a water softener or hot water recirculator, sewer line repair and replacing fixtures in the same location. These permits need no plan review, but the work is still inspected. The City fines work done without a required permit at double the permit fee.

Ownership splits underground. Scottsdale Water says the City is responsible for the sewer main, and the property owner maintains the sewer lateral, all the piping from the main to the house, including the tap where the two join. The water service line splits at the meter: the City owns the stretch from the main to the meter, and the private side after the meter belongs to the property owner. Knowing which side a problem is on tells you whom to call first.
