Lead Service Line Replacement Program

Greater Cincinnati Water Works (GCWW) is taking action to make the City of Cincinnati a lead-safe city. We are committed to protecting the health of its citizens from hazards caused by lead service lines.

The Lead Service Line Replacement Program is dedicated to removing all lead service lines within our service area, which includes much of Hamilton County and the City of Mason.

Although GCWW has no water transmission or distribution mains made from lead, some of the water lines serving individual properties are composed of the toxic metal. Roughly 40,000 lead lines are located within GCWW’s service area. The utility has set a goal of removing these lines during the next 15 years.



The figure (right) illustrates a typical service line ownership situation:

The water main lies underneath the street and the “public side” connection runs from the water main to the property line. GCWW owns and is responsible for this section of the connection.

The property owner owns the “private side” section from the property line into the home or business. This private side line may be made from lead. The property owner is responsible for this section. (Brass fittings, faucets and solder may also exist in the home or business and cause lead to be present in drinking water.)

To help property owners replace lead lines, GCWW offers a cost-sharing option to all customers that pays 40% of the cost for private-side replacement, up to $1,500.

Also, owners that meet certain income guidelines may be eligible to have 100% of the cost paid for through the Help Reduce Lead Pipes (HELP) initiative.

All work is completed by a contractor selected and certified by GCWW.
