#55 Continuously Rotating Sewer Screens

Description:  Seen here are six screen units at an interceptor drain in Detroit, Michigan.  These screens are used to clear debris from the water flowing through the drain in order to protect the pumps later on in the drain.  The screens work by continuous rotating in a conveyer like motion to ensure that clean screen is always exposed to the flow.  This continuous rotation ensures that the screens will never be blocked off plugging the flow of water which would cause damage to the screens.
