Wind River Environmental also offers expert hydro excavation services – the safest most efficient way to remove excavate soil. More accurate and non-destructive than hard-edge tools, our highly trained technicians utilize a combination of high-pressure water and an air vacuum to easily move or remove soil and uncover underground utilities. The hydro excavation (hydro vac) process is particularly effective for pipe and sewer line rehabilitation or landscaping. Using this process minimizes the disturbance or damages to the surrounding area.
