Let’s do something about it! Help the city map the lead! —>

Historic homes are part of Benton Park’s charm, but they are not without their quirks. From Kirkwood to Benton Park to all neighborhoods with any history (!), old lead pipes snake through houses like these throughout the St. Louis area.

There’s good news. St. Louis City is now in a two-year effort to identify lead pipes throughout its water system and replace them. The effort followed a rule issued in 2024 by the U.S. Environmental Protection Agency requiring lead pipes be replaced within 10 years. 

About 9,000 of lead service lines in St. Louis are already documented. But around 50,000 pipes remain unidentified, posing a challenge to water officials as they work to pinpoint the origin of pipes laid down nearly two centuries ago.

  • Check your address on the water service line map here.

    Make a note what material the map says your service line is made of, if reported.

  • Identify the material of your water service line and take 1–3 photos of your water service line to include in your report.

    Read the Service Line Identification Procedure document and follow the instructions to determine your water service line material.

    Missouri Department of Natural Resources has also created a video guide to help identify your service line material.

  • Report the material of your water line. Begin the process online here.

  • It doesn’t need saying that if you find out you have lead in your pipes you’ll want to do something about it.

    Once you’re reported your lead pipes, follow up with St. Louis Water. She’ll tell you who to talk to to verify that the pipes are replaced within 10 years.
