How service lines work

What is a service line?

A water service line is an underground pipe that connects a home or business to a water main, which carries the public water supply. Lead was the preferred piping material for service lines in the early 1900s. Cincinnati began requiring the use of copper pipes in 1928 and stopped using lead at that time. Some service lines on private property still contain lead, and GCWW is working to replace them at no cost to customers to ensure public health. We strive for minimal disruption and will restore the property after the work is completed.

How does the lead program work?

GCWW replaces lead and galvanized steel services lines:

  • For all child care facilities
  • During water main replacement projects
  • For individual replacements where lead service lines are leaking or test high for lead
  • In targeted areas using a prioritization model (coming soon!)
