Site 6 suds

  1. 1. Site 4: Sustainable Urban Drainage System (SUDS) Area When rainwater falls onto RPL’s roads and buildings it enters the surface water drainage systems around the site. Water running off these impervious surfaces tends to pick up gasoline, motor oil, heavy metals, trash and other pollutants from roadways and parking lots, as well as fertilisers and pesticides from lawns. SUDS systems provide more drainage in order to avoid flooding and hold this surface water in a natural environment such as wetlands which purify the water.. This is then slowly released into local watercourse in order to prevent contamination. SUDS use cost effective solutions to replicate natural systems with low environmental impact to drain away dirty and surface water run-off What is SUDS? Why use SUDS? Previous drainage system where contaminated surface water could freely run into the Wesley Brook water course and Priorslee Balancing lake SUDS depiction. Natural system where surface water creates pond onsite and provides habitat for many insects, amphibians and small mammals. Benefiting Biodiversity Not only does SUDS benefit a business through better drainage but it also increases site biodiversity. Wetlands are one of the most diverse productive ecosystems on the earth. The constant flow of water attracts an array of species of amphibians and reptiles, insects, plants and mammals. through collection, storage, and cleaning before allowing it to be released slowly back into the environment, such as into water courses. This is to counter the effects of conventional drainage systems that often allow for flooding, pollution of the environment – with the resultant harm to wildlife – and contamination of water sources used to provide drinking water. SUDS solutions are easy to manage, requiring little or no energy input (except from environmental sources such as sunlight, etc.), resilient to use, and being environmentally as well as aesthetically attractive. Examples of this type of system are reed beds and other wetland habitats that collect, store, and filter dirty water along with providing a habitat for wildlife. Sustainable urban drainage systems (SUDS) are a natural approach to managing drainage in and around properties and other developments. SUDS work by slowing and holding back the water that runs off from a site, allowing natural processes to break down pollutants. Ashlee Savage R1785
