ROMAG`s combined sewer overflow screens normally operate horizontally and require an installation length of at least 3 m. They are thus unsuitable for many, less recent structures with small or narrow spillway openings.
The new RSS combined sewer overflow screen with raised screen has been designed for opening widths of 40 to 120 cm respectively for structures characterised by cramped conditions. Apart from operating vertically, everything else functions in precisely the same way as on the well known ROMAG combined sewer overflow screen which have been used very successfully for many years now and which enjoy an excellent reputation on the market. The RSS is designed for flow rates of 80 - 300 l/s.
England and Ireland with their many small storm water relief tanks and basins are particularly interested in the RSS. During the course of a series of tests covering several months, a water and sewage authority in Britain`s north-east determined that the RSS retains 95 % of the solids and suspended matter > 6 mm in the relief water. The first RSS has already been sold to Spain.
