According to the National Resources Defense Council, stormwater runoff rivals or exceeds discharges from factories and sewage plants as a source of pollution throughout the United States. The Environmental Protection Agency identifies urban stormwaters as the second largest source of water quality damage in estuaries and a significant contributor to the damage to lakes, rivers, and bays. The full impacts of marginal pollution, particularly that caused by uncontrolled overflows, must be recognized now and planning needs to be initiated to improve sewerage sytem efficiencies in order to bring wastewater flows under control. Time is of the essence for municipal programs because corrective action is a time consuming process. Current research and development is elucidating the most efficient and least costly methods needed to restore and maintain water resources.Based on seminars presented by international experts for the U.S. EPA, Wet-Weather Flow in the Urban Watershed: Technology and Management covers a broad spectrum of urban wet-weather flow management and pollution abatement topics. The topics covered will assist municipal engineers, consultants, and academic researchers with design, cost, and water quality issues.
