Use the state page to narrow the local operator.
The correct utility matters more than the city label alone because the inventory record, notice language, and program rules can all change by operator.
Then open the utility page.
The utility page is where the local record separates overview, notification, program, and replacement-cost questions instead of flattening them into one generic answer.
Address truth still lives with the utility.

City of Phoenix Water Services
Phoenix says its public inventory uses non-lead lead galvanized and unknown categories, unknown lines are unlikely to be lead but still receive second verification and notices, mailed notifications went out as replacement work started in fall 2024, and if a lead or galvanized line is identified the city replaces the full line from the meter box to the house connection at no cost.

Tucson Water
Tucson Water says customers can view the service line inventory online, annual unknown or galvanized notices do not by themselves mean there is lead at the address, citywide inspections continue, and any confirmed replacement is scheduled at no cost to the customer.

Statewide support still flows through utility pages.
The state program page is useful when the question is which utilities in this state have verified support? It is not a replacement for the local utility record.
Use the rollup when funding is the first question.
Once the program or reimbursement path matters more than the inventory label itself, open the state program page and then move back into the matching utility page.
