City of Dubuque Water Department filter and testing guidance
Use this only as an interim protection layer when replacement is not immediate and the utility-specific next step is still unresolved.
Filters and testing are interim safety layers. They are not equivalent to a utility-confirmed full replacement path.
Use this only when replacement is not immediate: filter guidance sits below inventory, notice, and replacement decisions. It is not a substitute for line replacement.
Use local utility guidance, then narrow to certified interim protection.
Maintenance tips
Use a certified filter as an interim protection step, not as a replacement for line replacement.
Use testing when it changes the next action or clarifies uncertainty.
Return to the utility lookup if the service-line status is still unclear.
Testing should change the next action, not distract from the utility record.

Dubuque says its pilot-program page links to an online water service line inventory map, a spreadsheet, and a reporter form for customers to verify unknown service material while the city prepares to replace about 585 private lead service lines in three phases.

Dubuque explains lead health risk, tells residents to use the reporter form or request an inspection when they are unsure, and says selected pilot participants receive direct follow-up from the Water Department.
