EPA Water Service Line Inventory

IMPORTANT: Protecting the health and safety of your public water system 

The United States Environmental Protection Agency (EPA) is requiring public water systems, including the Sammamish Plateau Water and Sewer District (the District), to itemize all District and customer owned water lines for possible sources of lead in drinking water.   

You may see our crews at work on streets and curbs as the District establishes a mandatory water service line inventory to identify and eventually remove lead service lines.

The good news is our existing data shows very little or no lead service lines in the District. It’s also believed only a small percentage of homes in the District have private water lines containing lead. In such cases the EPA may require the District to seek customer consent and private property access as part of the service line investigation.

The inventory process is not expected to cause significant interruptions to water service or transportation delays on public roadways. The EPA requires the process to be completed by October 16, 2024.
