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 locate the applicable residential or commercial survey below, review the brochure regarding plumbing cross connections, and select the survey to begin. 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.
If you have questions please contact 402-441-5912, or email at backflow@lincoln.ne.gov. Thank you for assisting in compliance with State of Nebraska public water supply regulations and protecting Lincoln's drinking water.
