Summary
In Cincinnati, the property owner, not the Water Works department, must repair any leak in the private portion of the water service branch, from the curb valve into the building, once notified. Miss the repair deadline in the notice and the Greater Cincinnati Water Works can shut off service under City Municipal Code § 401-39 until repairs are inspected and approved.
That the portion of a water branch from points described in (a), (b), and (c) of Section 401-38 into the premises served, shall be maintained in proper condition by the owner. Failure to repair a leak or leaks in the time allotted on notice shall be sufficient cause to justify the department in discontinuing the service. When service has been discontinued for failure to repair leaks, it will not be restored until the department has been notified and is satisfied, after inspection, that repairs have been properly completed. In the case of a Lead Service Line as defined in this chapter, the owner shall comply with the requirements of 401-130 and shall temporarily repair and then permanently replace leaking or damaged Lead Service Lines.

Full Breakdown
Cincinnati Municipal Code § 401-39, "Maintenance of Service Branch by Property Owner," places the maintenance burden for the private side of a water service line squarely on the owner. Under § 401-38, the Greater Cincinnati Water Works (the department) is responsible for the public-side branch running from the main to the curb valve, to the paving edge if the valve sits under the street, or to the property-line side of a highway retaining wall. Everything from that point into the building, the portion described in § 401-38(a), (b), and (c), "shall be maintained in proper condition by the owner" under § 401-39.
If a leak develops on the owner's side, the department issues notice with a repair deadline. " There is no self-certification: a department inspector must confirm the fix before water is turned back on. A stricter timeline applies to Lead Service Lines. Section 401-39 cross-references § 401-130, which requires an owner with a leaking private lead line to have a certified plumber "temporarily repair the leaking private Lead Service Line within the time for repair provided in the notice," and then permanently replace it with a lead-free line, either through a certified contractor or by letting the department complete the replacement and bill the owner.
All repair or replacement work must be performed by a person holding a certificate of competency under § 401-41, unlicensed repairs do not satisfy the department's notice.
Violations & Fines
Ignoring a leak-repair notice lets the Greater Cincinnati Water Works shut off the property's water under § 401-39, with restoration withheld until a department inspection confirms the repair is properly completed. Section 401-39 itself sets no separate fine, so a violation falls under the chapter's catch-all penalty in § 401-999: a fine of not more than $200 for any Chapter 401 provision lacking its own specified penalty.
