LIFE DrainRain - RunOff Water Purification from Pavements: A Novel Integral System of Pervious Concrete Pavement & Insitu Water Treatment

Surface runoff is generated by rainfall flowing over the earth’s surface. Urban development over recent decades has rendered land increasingly impermeable, as the soils of agricultural lands and woodlands have been replaced by asphalt and concrete. When rain hits these paved/sealed areas, water gathers pollutants that have accumulated on their surface to generate a polluted runoff stream. This type of contamination is known as non-point source, or diffuse pollution. It has an intermittent flow and a heavily polluted first flush runoff stream generated within 30 minutes of a rain event. This often causes flooding during heavy rains, as a result of inadequate or failing urban drainage systems. Uncontrolled discharge of runoff and stormwater in urban watersheds lowers the quality of receiving waters, making it difficult to keep concentrations of priority pollutants (such as heavy metals and pesticides) below levels set by the Environmental Quality Standards (EQS) Directive, and to achieve good status of water bodies set by the Water Framework Directive (WFD). To tackle this problem, Sustainable Urban Drainage Systems (SUDS) are being adopted for the management of runoff and to mitigate the effects of stormwater, in line with the objectives of the Floods Directive.
