Private Utility Locating in Winlock, Washington
Twin City Locating provides professional private utility locating services throughout Winlock, Washington, helping homeowners, contractors, and property owners locate underground utilities before excavation begins. Locating underground utilities before digging helps prevent costly damage to infrastructure and ensures projects move forward safely.
​
Winlock is a small community in southern Lewis County located along the Interstate-5 corridor between Napavine and Castle Rock. The surrounding area includes rural residential properties, farmland, poultry farms, small residential neighborhoods. There is new development east of the town up to Interstate-5, including new industry and warehouses along with housing subdivisions. Many properties rely on private underground utilities such as septic systems, well water lines, and electrical service lines that extend across acreage.
​
Twin City Locating uses professional Ground Penetrating Radar (GPR) and electromagnetic locating equipment to identify underground utilities on private property before trenching, excavation, or construction.
Why private utility locating is important in Winlock
Washington 811 locates public utilities only up to the meter or service connection point. Utilities beyond that location — including septic systems, well water lines, and electrical service to buildings — are considered private utilities and usually remain unmarked.
​
Private utility locating is particularly important in Winlock because many properties include:
• septic systems
• private wells or water service lines
• underground electrical service lines
• irrigation systems on farmland
• utilities crossing large rural properties
​
Private locating helps prevent:
• damaging septic systems
• breaking underground water lines
• cutting electrical service lines
