Commercial drainage systems used to control the rate, volume and quality of storm water run-off from commercial development projects are referred to as Sustainable Drainage Systems (SuDS). These systems are intended to help avoid an increase in flood risk and will help to maintain natural water flow by encouraging storm water to soak into the ground or, where that is not reasonably practicable, will discharge it into watercourses or surface water/combined sewers at a controlled rate. These methods include balancing ponds, attenuation ponds and soakaways.
Gordon Low Products Ltd are a leading UK manufacturer and supplier of EPDM and Butyl Rubber pond liners used for attenuation ponds.
