WSSC outlines lead-service-line inventory, timeline and estimated $194M program cost
Summary
WSSC reported it has identified 97% of service-line materials, leaving 15,500 unknown services and 1,377 galvanized services that may require replacement; WSSC estimates a planning-level program cost up to $194 million and plans to publish its initial inventory by Oct. 16.
WSSC's lead-reduction briefing to the TIE committee, led by Jin Shin, summarized the utility’s inventory work, prioritization framework and outreach plans required under the revised Lead and Copper Rule.
Shin said WSSC relied on roughly 478,000 plumbing and permit records and related data to assemble an initial inventory. The utility reported it currently identifies material for about 97% of service lines, with 15,500 services of unknown material and 1,377 galvanized services flagged for potential replacement; Shin noted several of those flagged services date to the 1940s and require field verification.
WSSC presented a planning-level total program cost estimate of up to $194 million to support testing, replacement, outreach and program management. Shin said WSSC has secured $22 million from the state revolving fund but that significant funding gaps remain; he asked the committee for help coordinating with community programs and local partners to support outreach and finance mechanisms. WSSC plans to publish the inventory (including a public GIS map) by Oct. 16 and to expand community-focused outreach and customer support programs thereafter.
