Lead pipes in Arizona

In Arizona, the Arizona Department of Environmental Quality oversees public water systems' drinking water compliance. Under EPA's LCRI, every system must have a service line inventory by November 1, 2027 and notify affected homes. Your utility runs any replacement program.

Federal lead pipe money for Arizona
EPA’s current round (fiscal year 2026) gives Arizona $27,456,000 from the Drinking Water State Revolving Fund for lead service line replacement; at least $13,453,440 (49%) must go out as grants or forgivable loans. The state must apply for it by September 30, 2027. (EPA allotment tables, EPA memo.)
How it helps: the state lends or grants this money to water utilities for replacement projects. Residents benefit when their utility uses it, often to replace the private side at low or no cost. You can’t apply as a homeowner; ask your utility whether it has applied.
