City of Longview Awards Gibbs & Olson Lake Sacajawea Flushing Project

shapeimage_1 (5)Gibbs & Olson was hired by the City of Longview to evaluate alternatives to provide flushing water to Lake Sacajawea that will allow the city to maintain aesthetics and water quality in the Lake. The City constructed a new regional water treatment plant. Following construction of the new plant, an alternative means of providing “flushing water” to Lake Sacajawea needs to be implemented. Once decommissioned, the existing pumps, piping and pump control system will not operate properly for lake flushing and the existing fish screens must be replaced to meet Department of Fish and Wildlife (DFW) requirements.
