We serve customers throughout Centralia, Chehalis, Olympia, Tumwater, Lacey, Aberdeen, Ocean Shores, Longview, Kelso, Shelton, and surrounding Southwest Washington communities where private utilities often need to be located beyond what an 811 request covers.
Why Private Utility Locating Matters
Private utility locating helps reduce the risk of damaging buried lines on private property. Many underground utilities such as private water lines, sewer laterals, irrigation systems, electric feeds to detached structures, communication lines, and outdoor lighting may not be covered by standard 811 utility marking.
That makes private utility locating important before excavation, post setting, grading, trenching, boring, stump removal, drainage work, landscaping, utility repairs, and construction. Knowing where underground lines are located can help avoid costly delays, repairs, and property damage.
Our Private Utility Locating Services
Electromagnetic locating is used to trace conductive underground utilities that can be identified and followed with professional locating equipment. This method is often used for metallic or otherwise traceable private utilities such as certain electric, communication, and water lines.
This service is commonly used when a line has an accessible trace point and site conditions allow for efficient locating. It is often the first method used when utilities are believed to be conductive and continuous enough to trace accurately.
Ground penetrating radar is used when utilities may be non-conductive, difficult to trace, buried in congested areas, or otherwise not suited to standard electromagnetic locating. GPR can help identify subsurface anomalies and possible utility paths where traditional tracing alone may not provide enough information.
GPR locating is often requested for private utility locating on residential, commercial, and developed properties with unknown utility layouts, PVC lines, limited access points, or areas where multiple buried features may be present. This service is especially useful when additional subsurface awareness is needed before excavation.
Sewer sonde and camera locating is used to trace the path of sewer laterals and help identify the route from a structure toward the connection point. This service is often helpful for homeowners, contractors, and plumbers planning repairs, replacements, tie-ins, or excavation near buried sewer lines.
This method can be especially useful when the sewer line path is unknown, when records are incomplete, or when a property owner wants to better understand where a buried sewer lateral runs before work begins.
Magnetic locating can be used to detect certain buried metallic objects and features when other locating methods are not the best fit. This can help in situations involving specific buried items, metallic components, or site features that need to be identified before excavation or construction activity.
Which Service Is Right for the Job?
The right locating method depends on the property, the utility type, the available access points, and the level of certainty needed before digging. Some projects can be completed with standard electromagnetic locating, while others may require GPR or a combination of methods.
For example, a traceable conductive line may be a good fit for electromagnetic locating, while a non-conductive line, unknown route, congested work zone, or utility with limited access may call for GPR. Sewer laterals may require a sonde and camera setup, while certain buried metallic features may be better suited to magnetic locating.
When scheduling, it helps to describe the type of project, the utilities you are trying to locate, the work area, and whether the property is residential, commercial, or municipal. That helps determine the most effective approach for the site.
Common Reasons Customers Schedule a Locate
Before Digging or Excavation
Customers often schedule private utility locating before fence installation, trenching, grading, drainage work, retaining wall construction, stump removal, utility repairs, and any other digging activities on private property.
Before Utility Repairs or Replacements
Locating may be needed before repairing or replacing private water lines, sewer laterals, electric lines, communication lines, irrigation systems, or outdoor service connections.
Before Construction and Property Improvements
Private utility locating is also commonly requested before additions, shops, garages, pole buildings, driveways, sidewalks, patios, and other site improvements where buried utilities may cross the work area.
Private Utility Locating for Homeowners and Contractors
Homeowners often need help locating buried lines on private property where no clear records exist, especially on older properties, larger lots, rural parcels, and properties with added structures or irrigation systems. Contractors may need utility information before excavation begins so work can proceed more safely and with fewer surprises.
