Mayes Rural Water District #4 in Oklahoma has completed its initial service line material inventory and, as of June 2026, has identified 1,725 lead service lines, 6 galvanized requiring replacement (GRR) lines, and 1,263 service lines of unknown material. Under the federal Lead and Copper Rule Revisions, the district must notify affected customers and continue annual notices until each service line is fully free of lead, GRR, or unknown segments, which implies a multi‑year program of investigation and eventual replacement. This situation signals a substantial upcoming need for technical support to locate, verify, and replace lead and unknown service lines, as well as to manage public communication and regulatory reporting.Vendors offering lead service line replacement, utility locating, construction, GIS/asset inventory tools, sampling and lab services, and community outreach solutions can help the district plan and execute the required work, even though specific contracts or RFPs are not yet mentioned in the document.

The district has provided a contact phone number (918-825-4661) and email ([email protected]) for customers needing help identifying service line materials, indicating active engagement with the issue but no named external vendors yet.
