Denver Water 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.
Denver Water says its address map can show whether a home is one of the estimated 60000 to 64000 homes with a possible lead service line and publishes a longer replacement outlook from 2026 to 2031.
Denver Water says customers with identified possible lead service lines will be notified before neighborhood replacement work and that the inventory is built from records tests and inspections.
