Control of Pollution from Highway Drainage Discharges

Practical guidelines for highway drainage designers and water quality regulators. Part of CIRIA’s series of publications on highway drainage, this book reviews the pollutants that are likely to be present in highway drainage discharges, and assesses the impact that these can have on the receiving water. It also reviews the legal framework within which the discharges are made, and the controls that can be imposed on these discharges. It describes current drainage practice and the operation of different types of drainage structure. The book then presents guidelines for the planning and design of highway drainage systems in order to avoid pollution of the receiving waters and concludes with recommendations for future work to reduce the environmental impact of drainage discharges.
