METROPOLITAN DWID Lead Service Line Inventory
METROPOLITAN DWID serves approximately 45,570 people in Arizona. Like all US water utilities, it is required by federal law to maintain an inventory of lead service lines—the pipes that connect homes to the public water system—and share that information with customers.
What we know about METROPOLITAN DWID's lead pipes
Currently, the utility has not yet completed or made public a detailed inventory of its lead service lines. This does not mean there are no lead pipes in the system; it means the inventory work is still underway or the results have not been disclosed publicly.
The utility draws its water from groundwater sources, which is one factor that can influence corrosion control decisions and lead risk.
Why this matters
Lead service lines are a direct pathway for lead to enter your home's drinking water, especially if the water is corrosive or if pipes are disturbed. Even low levels of lead exposure can affect children's development. If you live in this service area, knowing whether you have a lead service line is an important first step in protecting your family.
Getting answers from your utility
METROPOLITAN DWID is required by the EPA to:
- Maintain a complete inventory of lead service lines
- Make that inventory available to customers
- Develop a timeline for replacing known lead service lines
Contact METROPOLITAN DWID directly to ask:
- Whether your address has a lead service line
- What the utility's replacement timeline is
- Whether any water treatment is in place to reduce lead leaching
- How to request a free or subsidized water test
You can also request a copy of their latest Lead and Copper Rule compliance report, which must include inventory status.
Federal funding for replacements
Utilities across the country are receiving federal grants and low-interest loans through the Bipartisan Infrastructure Law to accelerate lead service line replacement. Ask your utility whether it is receiving funding and how residents can apply for assistance with replacement costs.
Next steps for residents

- Request a water test if you are concerned about lead exposure in your home
- Check with your local health department for testing resources or guidance
