Private Utility Locating in Napavine, Washington
Twin City Locating provides professional private utility locating services throughout Napavine, Washington, helping homeowners, contractors, and property owners locate underground utilities before excavation begins. Locating utilities before digging helps prevent costly infrastructure damage and allows construction projects to proceed safely.
​
Napavine is located along the Interstate-5 corridor in southern Lewis County, between Chehalis and Winlock. The community includes residential neighborhoods, commercial properties near the interstate, and rural residential land surrounding the town. Many underground utilities serving these properties may not be clearly documented or visible on property records.
​
Twin City Locating uses professional Ground Penetrating Radar (GPR) and electromagnetic locating equipment to identify underground utilities on private property.
Why private utility locating is important in Napavine
Washington 811 locates public utilities only up to the service connection or meter. Utilities beyond that location — including sewer laterals, private water service lines, and electrical service lines — are considered private utilities and usually remain unmarked.
​
Private locating is particularly important in Napavine because of:
• residential developments near the I-5 corridor
• older sewer laterals in established neighborhoods
• underground electrical service lines
• utilities serving commercial buildings near the interstate
• undocumented underground infrastructure
​
Private utility locating helps prevent:
• breaking sewer laterals
• cutting electrical service lines
• damaging water service lines
• interrupting communication infrastructure
• costly repairs and construction delays

Ground Penetrating Radar locating in Napavine
Ground Penetrating Radar is especially useful in Napavine because many underground utilities are constructed from non-metallic materials such as PVC or polyethylene pipe that are installed without a tracer wire.
These utilities may not respond to traditional electromagnetic locating equipment.
​
GPR can help locate:
• PVC sewer lines
• plastic water service lines
• underground drainage system
• future conduit placement without tracer wire
• unknown buried infrastructure
