ABSTRACT:
A diverter screen for efficiently handling solid and floatable objects in combined sewer overflows and storm water runoff systems is disclosed. The screen is formed of a mechanical bar screen, one or more regulator or overflow chambers, and a deflector plate for diverting the solids and floatables into the outgoing sewage interceptor channel. The bar screen sits on a shelf in a concrete channel, and is sized to capture solids and floatables that must be prevented from entering the rivers, lakes or oceans The bar screen uses a downward rake motion to push solids and some floatables into the outgoing interceptor, while other floatables are allowed to drain out as the regulator channel drains.
