Official utility action
Use the utility record to confirm whether the notice represents a known line, a modeled risk, or a still-unverified material category.
Owners stay on an owner-managed path unless private lead is discovered and Madison Water confirms rebate eligibility so this route remains a rebate guide rather than a no-cost program page.
Do not let a notice flatten the ownership boundary.
Do not overread this notice. The utility's exact category definitions, lookup record, and replacement path still control the real decision.
Action step
Check the exact notice language against the official utility page.
Action step
Do not treat a potential line notice as proof of parcel-level certainty unless the source says so.
Action step
If replacement is not immediate, use the interim protection route next.
Do not overread this notice
Known, potential, and unknown mean whatever this utility says they mean. Do not import another utility's definitions.
Do not overread this notice
A notice is not parcel certainty unless the utility lookup or map confirms the specific address.
Do not overread this notice
Filter and testing are interim steps, not equal substitutes for replacement when a local replacement path exists.
