Private Utility Locating in Ilwaco, Washington
Twin City Locating provides professional private utility locating services throughout Ilwaco, Washington, helping homeowners, contractors, and property owners locate underground utilities before excavation begins. Accurate locating helps prevent costly infrastructure damage and ensures construction and repair projects proceed safely.
Ilwaco sits at the southern end of the Long Beach Peninsula near the Columbia River entrance, where residential properties, commercial buildings, and fishing industry facilities rely on underground infrastructure. Coastal soil conditions, shifting ground, and aging utilities make accurate locating especially important before digging.
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 Ilwaco
Washington 811 locates public utilities only up to the service meter or connection point. Utilities located beyond that point — including sewer laterals, private water lines, and electrical service lines — are considered private utilities and are usually not marked.
​
Private utility locating is particularly important in Ilwaco because of:
• coastal soil conditions
• marina and port infrastructure
• older sewer and drainage systems
• utilities installed during early coastal development
• commercial and fishing industry buildings
​
Private locating helps prevent:
• breaking sewer laterals
• damaging underground water lines
• cutting electrical service lines
• damaging drainage infrastructure
• costly repairs and project delays
​

Frequently Asked Questions
Q: Can utilities be located near marina facilities?
A: Yes. Underground utilities serving marina and waterfront infrastructure can often be located using electromagnetic locating and Ground Penetrating Radar.
Q: Do coastal soil conditions affect locating?
A: Sandy coastal soils often allow Ground Penetrating Radar to work effectively for locating underground utilities.
Q: Can sewer lines be located before excavation?
A: Yes. With an accessible cleanout, we can send a transmitter camera down the line to locate. If there is no cleanout, we can use ground penetrating radar to find sewer or septic lines.
