英格兰和威尔士环境署负责评估公路径流的影响，并监测为减少有害影响而采用的处理系统/程序。该机构正在研究如何通过最佳管理做法改进地表水管理，并计划与公路局合作实现这一目标。正在考虑的处理方案之一是人工湿地。已经制定了准则草案，以提供关于其设计的信息。本文介绍了程序进行环境敏感性分析，以确定是否处理人工湿地是适当的。需要关于水的质量和数量以及接收环境的敏感性的信息。还需要考虑立法立场，特别是与水的排放质量和接收环境的养护状况有关的立法立场。决定最适当湿地设计准则的因素包括交通负荷量、道路排水面积、土地供应、成本以及接收水体的大小/范围和类型。建议在总体设计中纳入以下结构：隔油池和淤泥收集器、溢漏控制装置、沉淀池、植物湿地和最终沉淀池。运行和维护程序和功能湿地的监测要求进行说明。
The Environment Agency for England and Wales are responsible for assessing the effects of highway runoff and for monitoring the treatment systems/procedures which have been introduced for the reduction of deleterious effects. The Agency is looking into the improvement of surface water management in terms of best management practices and plans to work in partnership with the Highways Agency to achieve this aim. Among the treatment options being considered are constructed wetlands. Draft Guidelines have been developed to provide information on their design. This paper describes procedures for carrying out an Environmental Sensitivity Analysis to determine whether treatment by a constructed wetland is appropriate. Information on water quality and quantity is required as well as the sensitivity of the receiving environment. The legislative position, particularly in relation to the discharge quality of the water and the conservation status of the receiving environment, needs also to be considered. The factors that will determine the most appropriate wetland design criteria include traffic loadings, road drainage area, land availability, cost and the size/extent and type of the receiving water body. The following structures are recommended for incorporation in the overall design; oil separator and silt trap, spillage containment, settlement pond, vegetative wetland and final settlement tank. The operation and maintenance procedures and the monitoring requirements for a functioning wetland are described.
