The Copa® raked bar screen is ideally suited to both new and existing combined sewer overflow (CSO) chambers where high frequency spills can be expected.

Its modular design is ideal for retro-fit installations (requiring little or no civil work to the existing CSO chamber) and allows the unit to be assembled below ground through just a 600mm diameter manhole.

The Copa mechanical raked bar screen is designed to be installed at any CSO location, whether below ground onto an existing storm overflow weir or at a sewage treatment works within the works inlet storm overflow chamber.

The screens, baffles and all fixings are constructed in grade 304 or 316 stainless steel. The screen components have been designed such that they can be dismantled individually with access only from the storm side of the emergency weir.
