Federal regulations set by the Environmental Protection Agency require all water systems to develop an inventory of service line materials.  A service line is the pipe connecting a water main to a building.  This file indicates the results of the City of Columbus’ water line investigations, which are now complete.

• System-owned portion of the service line: Pipe generally located between the City of Columbus’ water main and your water meter.  This pipe is owned and maintained by the City of Columbus.
• Customer-owned portion of the service line: Pipe generally located between your water meter and your home/building.  This pipe is maintained by the property owner.

Service lines from these investigations have been categorized as non-lead, which means that the service line does not contain lead pipe.  These service lines are typically made of copper, plastic, or steel. While Galvanized Requiring Replacement and Lead are listed service line categories, it is important to note that the City of Columbus water inventory has no lead or galvanized requiring replacement water service lines identified. Customer-owned portions of the service lines were categorized when information was available, otherwise they have been identified as unknown.
