Eaton Wash Dam Inlet/Outlet Works Rehabilitation (Water Resources)
This project will replace the deficient outlet tower with a new hydraulic power system. The gates will be rehabilitated for reduced leakage and improved reliability. A new low-flow valve will provide precise control and improved water quality for ground water recharge. All existing lead-based paint and hazardous materials will be abated, and surfaces will be coated with new protective coatings, NSF certified for use with potable water. The project will also improve dam safety with erosion and slope protection measures at the downstream toe of the dam. New gates and signage will improve public safety and aesthetics of the facility. The project promotes sustainability with respect to water conservation and water quality benefits, extending the useful life of existing equipment and facilities, and reducing resources for future maintenance. The total project cost is approximately $3.5 Million.
