Colville Groundwater Correction

The purpose of this project is to mitigate drainage onto, through and from a United States Border Patrol station in Colville, Washington. For this project, over 7,000 tons of soil were removed from the site to create positive drainage, on both side of the equine barn. Over 305 tons of asphalt was replaced. A infiltration drainage gallery and stormwater pond were established directly south of the administration building. At the completion of the project, 45 cubic yards of concrete valley gutters was placed, new security fencing, 400 feet of horse fence(s), 12,000 SY of landscaping, and irrigation was placed back into service.
