Lead Service Lines in Tempe, Arizona

What you need to know

Tempe serves about 169,774 people through 16 different water systems. The good news: no lead service lines have been identified in any of these systems so far.

That said, "not yet identified" doesn't mean they don't exist. Many water systems across the country are still in the process of mapping their underground pipes. If your home was built before the 1980s, there's a chance—however small—that a lead service line connects your property to the main water line under the street.

How to find out if you have a lead service line

Contact your water utility directly. The City of Tempe (which serves about 165,000 residents) maintains records of service line materials. They can tell you whether your home's connection is made of lead, copper, galvanized steel, or plastic.

You can also:

  • Look at your property's building permit or original plumbing documents if you have them
  • Hire a licensed plumber to inspect the line running into your home from the street
  • Request a water quality test—your utility can recommend an approved lab

What about lead in your tap water?

Lead service lines are only one source. Lead can also enter water if you have lead solder, lead-containing fixtures, or corroded pipes indoors. Even with newer copper pipes, water chemistry matters.

The City of Tempe tests its water regularly for lead and other contaminants. If you're concerned about your specific home, ask your utility for a free or low-cost lead test, or order a test kit from a certified lab.

If you have young children or are pregnant, the CDC recommends taking lead exposure seriously. Talk to your pediatrician or doctor about your individual risk.

Next steps for residents

  • Call the City of Tempe Water Utilities to ask about your service line material—they have records by address
  • Request a free lead test from your utility if available
  • Check your home's age—pipes installed before 1986 are more likely to contain lead
  • Visit the EPA's drinking water page for more information on lead and water safety
