Inventory of Lead Service Lines

Since 1994, Summerville CPW has monitored lead and copper concentrations in the drinking water from a group of residences constructed prior to 1986, when the national ban on the use of lead in water lines went into effect.  All results have been lower than the EPA action level.  By October 2024, all water utilities are required to complete an inventory of all service line materials and make it accessible to their customers.  Summerville CPW has completed its inventory and submitted it to SCDHEC for review, using data collected from decades of maintenance and inventory records, interviews with long-time employees, and an EPA approved statistical model.  Based on this data and results from regular sampling, Summerville CPW can certify with a high level of confidence that no lead service lines are present in its water distribution system.
