Lead Service Lines in Phoenix
Phoenix serves approximately 1.7 million people. Like most US water systems, Phoenix may have lead service lines—the underground pipes connecting homes to the water main. Whether your home has one depends on when it was built and which neighborhood you live in.
What you need to know
Lead service lines were legal and common in US homes built before the 1980s. When water sits in a lead pipe overnight or for several hours, small amounts of lead can dissolve into the water. The EPA and CDC both agree: no level of lead in drinking water is safe, especially for children.
The good news: Lead is preventable. If you have a lead service line, you have concrete options—from flushing your tap water before use, to testing it, to full replacement.
Phoenix's current status
Phoenix has not yet completed a full inventory of lead service lines in its system. This is common; many large water systems are still working through detailed pipe records. Without a complete count, we don't know exactly how many homes in Phoenix may be affected.
Phoenix has not received funding under the Bipartisan Infrastructure Law for lead service line replacement (as of the last update to this directory).
What to do now
First, find out if your home is at risk. Call Phoenix Water Services at the number on your latest water bill, or visit their website. Tell them your address and ask:
- When was your home built?
- Does your property have a lead service line?
- Has your water been tested for lead?
Many older homes in Phoenix do have lead lines, but not all. Even if yours does, treatment and replacement options exist.
Second, if you're concerned about your family's health, contact your pediatrician or call the CDC's National Lead Information Center at 1-800-424-LEAD (5323).
Next steps for residents
- Contact Phoenix Water Services with your address to ask about your service line material
- Request a free lead water test if you're unsure or live in a home built before 1990
- Visit the CDC website for guidance on protecting your family while you investigate further

Frequently asked
Does Phoenix have lead in the water?
Lead comes from lead service lines—pipes connecting homes to the water main—not from the source water itself. Phoenix's water system may have lead lines, but a complete inventory hasn't been published yet. Contact your water utility to find out if your home is affected.
How do I know if my house has a lead service line?
Call Phoenix Water Services with your address and ask. They can check their records. Homes built before the 1980s are more likely to have lead lines, but the only way to know for sure is to ask your utility or hire a plumber to inspect it.
Is it safe to drink tap water in Phoenix?
Phoenix's treated water meets federal safety standards. However, if your home has a lead service line, lead can leach into your water while it sits in the pipe. Using a filter, flushing the tap before use, or replacing the line are all effective ways to reduce exposure.
Will Phoenix replace lead service lines for free?
Phoenix has not announced a lead service line replacement program funded by the recent federal infrastructure law (yet). Contact your utility directly to ask about current replacement programs, costs, or assistance options available in your area.
