Private Utility Locating Services in Washington
Twin City Locating provides professional utility locating services throughout southwestern Washington to help homeowners and contractors identify underground utilities before digging or construction begins.
Many properties contain underground lines or features that are not clearly visible or documented. Our locating services help reduce the risk of damage, unexpected repairs, and safety hazards by identifying what is below the surface before work starts.
How Utility Locating Helps Before Digging?
811 is not only the law, it is free. Allow public utilities to be marked by their respective owner. Everything after the meter or main line, is the homeowner or property owner's responsibility. For that reason, Twin City Locating offers private utility locating.
Utility locating is recommended before any project that involves digging, trenching, or ground disturbance. Locating underground utilities ahead of time helps prevent costly damage and delays, especially on properties with older or undocumented installations.
Services We Offer
-
Electromagnetic (EM) Locating - Conductive Utilities
​
Electromagnetic locating is used to trace conductive utilities such as metal pipes, tracer-wire equipped plastic lines, and energized electrical or communication cables. This method is effective when the utility can carry or receive a locating radio frequency signal.
​
​
Ground penetrating radar is used to detect non-metal underground utilities and subsurface features where traditional locating methods are not effective. This service is commonly used to locate plastic water lines, PVC sewer lines, irrigation systems, and unknown buried features.
Magnetic locating is used to find buried ferrous objects such as property pins, valves, manholes, and other underground features made of iron or steel.
​
Sewer scope and sonde locating is used to trace underground sewer laterals and piping by inserting a camera and transmitter into the line. This service is commonly used when planning repairs, replacements, or confirming the path of sewer lines.
​When to Schedule Utility Locating
Utility locating is commonly scheduled before:
• Fence installation
• Trenching or excavation
• Sewer or water line repairs
• Concrete cutting or driveway work
• Construction or site development

Scheduling locating services before digging helps reduce the risk of utility strikes and costly delays.
