Lansing Board of Water and Light 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.

Use the source stack that supports this interim route.
BWL says it completed removal of all known active lead service lines and galvanized requiring replacement lines in 2016 and verified by October 16 2024 that no lead, galvanized requiring replacement, or unknown service lines remain.

BWL says residents should still follow lead safety guidance for indoor plumbing and that the utility continues periodic lead and copper testing to confirm corrosion control remains effective.
