Rincon del Diablo Municipal Water District (Rincon Water) has completed the initial lead service line inventory required by the U.S. EPA’s Lead and Copper Rule Revisions. The deadline for the initial inventories was October 16, 2024.
Through completing a historical records review and field investigations, Rincon Water has determined it has no lead or galvanized requiring replacement service lines in its distribution system. This includes any privately-owned or customer-owned service lines.
Rincon Water reviewed all applicable sources of information, including:
- All construction and plumbing codes, permits, and existing records or other documentation which indicates service line materials;
- All water system records, including distribution system maps and drawings,, historical records on each service line connection, meter installation records, historical capital improvement or master plans, and standard operating procedures;
- All inspections and records of the distribution system that indicate service line material, including inspections conducted during the course of normal operations (e.g., checking service line materials when reading water meters or performing maintenance activities; and
- All previous service line or meter replacements were conducted.
In addition to reviewing the above sources of information, Rincon Water physically inspected all service lines in its distribution system, regardless of ownership. All service lines were verified nonlead.
Rincon Water will update service line material information obtained from normal operations, such as service line maintenance, installation, or water meter readings, after October 2024 and will update the initial inventory accordingly.
