Stormwater Screening to Meet the Urban Wastewater Treatment Directive

A large quantity of solid matter often builds up in a sewerage system during periods of dry weather. Typically, under storm conditions, this solid matter will be flushed through the system to the works inlet, causing rapid blinding of the already hydraulically overloaded inlet screens, and consequent backing up and overflow of the sewage system. The effect of an unscreened storm water overflow is disastrous.
