The increase in road construction has highlighted the issue of increased volumes of highway runoff and the potential pollution of groundwater and surface waters. The Environment Agency are involved in the assessment of the effects of urban and highway runoff and mechanisms for the protection of water quality. Constructed wetland systems have been used extensively for the treatment of municipal, industrial and agricultural effluent, but they have only been recently developed and investigated for the treatment of urban surface runoff. The aim of this Guidance Manual is to provide information on the design, construction, operation and maintenance of constructed wetlands, including the configuration, planting medium, water levels and type and extent of the vegetation in order to effectively treat urban and road runoff. This Manual includes the following information: - Examples of the various types of Wetlands and how they work; - guidance regarding the design and planting of a constructed wetland system and the retrofitting of existing treatment structures; - the performance and costs of urban wetlands; - the operation and maintenance requirements for constructed wetland systems; - the use of wetlands to encourage wildlife and enhance the landscape; - the implementation of Sustainable Drainage systems (SuDS), including constructed wetlands, and catchment planning; - the use of decision support approaches for selecting SuDS systems; - recommendations for future research.
