Iowa City, IA Water Use Rules: Leak Reporting Duty (2026)

Iowa City Code section 16-3C-3(C), Maintenance Of Service, puts the repair burden squarely on the property owner: all service lines from the distribution water main to the building are maintained at the owner's expense, and any leak or other defect must be promptly repaired or replaced by the owner. If a leak isn't fixed promptly, the code lets the city act without going to court: after written notice to the owner, the Water Division may turn off service at that address until the repairs or replacement are complete, cutting off running water rather than issuing a fine first.

The 2023 and 2025 amendments (Ord. 23-4916 and Ord. 25-4971) layered on a stricter rule for lead service lines. Under subsection F, any lead line that develops a leak or other defect cannot simply be repaired; it must undergo a full lead service line replacement, and the method of connection at the main must follow the city's adopted tapping policies. Subsection E separately bars repairing, partially replacing, or reconnecting a lead service line to the distribution main under any circumstance. Owners planning a lead line replacement must report it to the Iowa City Water Division before work begins, and the full cost, for both ordinary leak repairs and lead replacements, falls on the property owner.

Abandoned service lines carry a parallel duty under subsection D: they must be permanently closed off at the main within one calendar year of abandonment, at the owner's expense, or the city completes the work itself and bills the property owner.
