Interim protection

Council Bluffs 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.

Interim only

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.

Certified filter selection

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.

Water testing steps

Testing should change the next action, not distract from the utility record.
