Private Utility Locating in Shelton, Washington
Twin City Locating provides professional private utility locating services throughout Shelton, Washington, helping homeowners, contractors, and property owners locate underground utilities before excavation begins. Accurate locating helps prevent infrastructure damage, reduces project delays, and allows excavation work to proceed safely.
Shelton and surrounding Mason County communities include residential neighborhoods, rural acreage properties, and shoreline homes around Oakland Bay and Hood Canal. Many of these properties rely on private underground utilities that are not marked by Washington’s public utility locate system.
Twin City Locating uses professional Ground Penetrating Radar (GPR) and electromagnetic locating equipment to identify underground utilities located on private property.
Why private utility locating is important in Shelton
Washington 811 marks public utilities only up to the meter or service connection point. Utilities beyond that location — including septic piping, electrical service to detached buildings, and water lines from wells — are considered private utilities and are usually not marked.
​
This is common in Shelton because many properties include:
• septic systems
• private wells
• underground electrical service to shops or garages
• shoreline utilities
• long underground utility runs through wooded terrain
​
Private utility locating helps prevent:
• damaging septic systems
• breaking underground water lines
• cutting electrical service lines
• damaging irrigation systems
• expensive repairs
Utilities commonly located on Shelton properties

Utilities commonly located include
• septic system piping and drain fields

Many Mason County properties have utilities installed across large wooded lots, making accurate locating important before excavation.
Ground Penetrating Radar locating in Shelton
Ground Penetrating Radar is particularly valuable in Shelton because many underground utilities are constructed from plastic materials such as PVC or polyethylene pipe. These utilities may not respond to electromagnetic locating equipment.
​
GPR can help locate:
• septic system piping
• plastic water service lines
• PVC sewer lines
• underground drainage pipes
• electrical conduit without tracer wire
• unknown buried infrastructure
​
