Learn all about locating and marking in the water utility industry.
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
- Marker clearly defines the location of the facility
- If connection point and premise point can be identified, may improve ability to determine the path of the service line

A sewer district improves contractor’s ability to accurately identify pipe location, and reduce accidental force main damage. In an effort to meet EPA requirements, this resulted in less environmental impact from overflow and related cleanup costs.
