Foreword: Stormwater Management and Abatement of Combined Sewer Overflow Pollution

Performance of stormwater detention tanks for urban drainage systems in northern Italy

“…During 1960s the impact of rainwater runoff on receptors bodies was evident [1], however only until 1990 the flooding of rainwater became a real concern [2]. Since then, have been managed research and standards that directly involve urban rainwater [3,4], and started different strategies to improve urban conditions when there are high amounts of rainfall.…”

“…The first evidence of the impact of combined sewer overflow CSO on receiving water bodies came to light in the 1960s but it was not until 1990s that reducing the CSO became a concern (e.g. Marsalek and Kok [10]; Butler and Davies [11]). Consequently, international strategies on environmental pollution refer directly to urban stormwater discharges: the U.S Clean Water Act requires cities and states to reduce the pollution of CSOs; the European Water Framework Directive (Directive 2000/60/EC) implies that European countries should promote plans to suppress the most obvious sources of pollution, including CSOs, to restore their aquatic systems to a "good ecological status".…”
