Key Takeaways A utility survey was performed to gather cost data and information on identification and verification methods. In compiling a service line inventory, water utilities need to account for using multiple verification methods at some locations to improve accuracy. Costs vary significantly between verification methods for developing accurate service line inventories and should be accounted for in a water system's planning efforts. The costs for lead service line replacements are estimated to be higher than originally reported when accounting for auxiliary costs to utilities.
