Gibbs & Olson was selected to complete surveying, design and construction phase services for the City’s combined sewer overflow (CSO) separation project. The project includes over 9,000 feet of new storm sewer pipe along 8th through 12th Streets. The $6 million project represents the next step in completing the City’s 20 year program of reducing or eliminating CSOs. This project includes the physical separation of stormwater from the sanitary sewer system. The new storm sewer conveyance system will bypass the City’s interceptor to the wastewater treatment plant and discharge the stormwater, which has not been co-mingled with sanitary sewer, directly to the Columbia River.
