Cross Connection Plumbing Survey

The safety of Lincoln's water is very important. The Nebraska Department of Health and Human Services requires water utilities in Nebraska to have all water customers inspect their plumbing systems for potential cross connections with the public water supply and ensure these connections are properly protected against backflow or back-siphonage.

Please review the brochure regarding plumbing cross connections, and choose Residential or Commercial below to begin the survey. If you would prefer to print the survey and mail it in, please complete the PDF version and mail to: Lincoln Water System, 2021 N 27th Street, Lincoln, NE 68503.
