At the Cheney Reservoir Pump Station, there are strainers that separate larger debris, such as mussel shells, from the water between the intake and the pumps. These strainers were recently replaced. The new strainers remove anything larger than 1/8-inch to solids debris waste. The new strainers are also a type that will not grind and pass some debris like previous versions appeared to be doing. In the very rare instance that debris passes through the strainers, it will be captured in the lime residuals and removed with the waste stream.
