City of South Bend Water Works 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.

South Bend Water Works says residents should use its service line inventory map to check address status, complete the city service line survey to verify private-side material, and use 311 or water quality staff for free lead testing and follow-up.

South Bend says more than 34000 customers were asked to complete the service line material survey for EPA inventory and mapping requirements and that 311 or the water quality team remains the help path while private-side verification continues before the city overstates replacement timing.
