Water and Wastewater Line Locating

Find it the first time! The 3M™ Electronic Marker System (EMS) for Water and 3M™ Electronic Marker System (EMS) for Wastewater helps save time and money by enabling field crews to quickly pinpoint the location of buried facilities including valves, bends, clean-outs and road crossings. Using EMS markers for water and sewer pipe location during construction, installation and maintenance virtually eliminates the time consuming search for hard-to-locate facilities.

3M EMS markers used for water and sewer pipe location are color-coded to APWA standards for visual reference and water utilities have their own frequency to reduce location errors. For water and sewer pipe location, markers are color coded as follows:

Water Utility: BlueGeneral Purpose/Reclaimed Water: PurpleWastewater Utility Markers: Green

3M EMS Water series can be used to locate:
 

  • Buried valves
  • Clean-outs
  • PVC pipeline
  • Road crossings
  • Pipeline paths
  • Service stubs
  • Bends
  • Trees
