  • Stormwater Treatment: Priority pollutant behaviour in stormwater BMPs

    The term Stormwater Best Management Practices (BMPs) (also known as sustainable urban drainage systems; SUDS) refers to a wide range of stormwater control systems which enable the planning, design and management of stormwater to be tackled equally from water quantity, water quality and amenity perspectives (). Commonly used systems include: Storage systems (e.g. retention ponds and constructed ...

  • Rough set approach to the evaluation of stormwater pollution

    This paper addresses the problem of urban stormwater quality and its impacts on the receiving water. In order to describe this phenomenon, research aimed at creating a mathematical model of pollution has been conducted. Although various deterministic and stochastic models exist already, the quality of stormwater phenomenon deserves a very careful and thoughtful validation. In order to take ...

  • Controlling urban stormwater pollution by constructed wetlands: a Canadian perspective

    During the past 20 years, Constructed Stormwater Wetlands (CSWWs) have attained broad acceptance in Canada as effective measures for stormwater management. CSWWs are used mainly for improving stormwater quality by providing sufficient treatment volumes in shallow permanent pools. This leads to high requirements for land, which is one of the constraints on CSWWs use. Even though CSWWs perform less ...

  • Preliminary investigation into the pollution reduction performance of swales used in a stormwater treatment train

    Permeable pavements have been shown to be effective stormwater treatment devices that can greatly reduce surface runoff and significantly improve the quality of stormwater runoff in urban areas. However, the potential problems with sediment clogging and consequent maintenance requirements have been identified as the main barriers to more widespread adoption of permeable pavements in urban ...

  • Influence of the land use pattern on the concentrations and fluxes of priority pollutants in urban stormwater

    This paper presents the results of the concentrations (μg/L) and fluxes (g/ha) of priority substances in stormwater from three watersheds with different land use patterns (namely, residential, urban dense, high urban density). Samples were collected at the outlet of these watersheds. Thirteen chemical groups were investigated corresponding to 88 individual substances before treatment. Results ...

  • Seattle Stormwater Management

    Since the 1990s the city of Seattle – a major coastal seaport in the North West of the U.S. – has invested heavily in cleaning up and reducing severe pollution of the water environment. Some of the ideas to help prevent water pollution can be of great inspiration to cities in Europe. Read more ...

  • Stormwater: Questions and Answers

    The whole subject of Stormwater is complicated. Here's a chance for you to check out some of the most frequently asked questions about stormwater . . . and their answers. What is an NPDES (National Pollutant Discharge Elimination System) permit? The Clean Water Act prohibits anybody from discharging 'pollutants' through a 'point source' into a 'water of the United States' unless they ...

  • Modeled Flow Duration Variations, Pollutant Discharges, and Costs for Different Stormwater Controls

    ABSTRACTRunoff volume and pollutant discharges increase with development, with associated detrimental receiving water effects. These increases can be partially controlled by installing stormwater control practices, such as wet detention pond at outfalls, using conservation design controls such as grass swales and bioretention devices, and by improved development practices that reduce the amounts ...

  • Removal patterns of particulate and dissolved forms of pollutants in a stormwater wetland

    A 0.23-ha pilot wetland was constructed to examine its effectiveness for the control of nonpoint source pollution (NPS) from a 7.42-ha agricultural watershed in Korea. This research emphasised the removal patterns of particulate and dissolved forms of pollutants on both dry (base flow) and wet days (storm flow). The hydraulic loading rates were high on rainy days, with an average value of ...

  • Warning! Beware stormwater product

    Warning! Beware of a storm water insert sold under the trade mark "Safe Drain".  This product holds water in the open position.  Standing water can present both odor and health issues.  In 2004, Cameron M. Colson patented a leading storm water drain insert that utilized a butterfly valve mounted inside the storm water insert that aided in spill control.  This Design was ...

  • The urban stormwater farm

    Currently more than 3 billion people live in urban areas. The urban population is predicted to increase by a further 3 billion by 2,050. Rising oil prices, unreliable rainfall and natural disasters have all contributed to a rise in global food prices. Food security is becoming an increasingly important issue for many nations. There is also a growing awareness of both ‘food miles’ and ‘virtual ...

  • Stormwater Management for Urban Environments

    IntroductionElmhurst College, a hundred-thirty-five year old private learning institution, is proceeding with a campus redevelopment project that will include a one hundred seventy bed residence hall. In addition, the college continues to be a role model for sustainable site design and an educational resource for both students and the community.The need for additional housing, due to ...

  • Stormwater and lamella settlers: efficiency and reality

    ABSTRACTTwo settling devices treating rainwater from urban drainage areas and equipped with secondary sludge treatment were monitored over a period exceeding one year. The two devices differ in their design and in the quantity and quality of effluents received. Full analyses over approximately 30 mean samples of the intake and discharge effluents allowed judgment of the mean efficiency of ...

  • Stormwater Best Management Practices (BMP)

    Storm water is the result of rain or snow melt that collects in an area that can drain from into a nearby body of waters such as a lake or river. The water can collect on roof tops, parking lots, saturated ground, roads, etc. The problem is that many of the pollutants of our modern living such as oil, grease, pesticides, sediment, salt, and animal waste are washed away within the storm water and ...

  • Modeling of Sedimentation in Stormwater Detention Basins

    ABSTRACTTo minimize the non-point source pollution from roadway surface, the Texas Department of Transportation (TxDOT) initiated a research project for design of a small footprint non-proprietary detention basin, which consists of pipes and box culvert sections with specialized inlet and outlet system. A conceptual model was developed to estimate particle removal efficiency of the rectangular ...

  • Lake Lenexa Stormwater Management Project

    Using cutting-edge technologies to significantly upgrade wastewater treatment in coastal areas, B&V Water helped Southern Water keep pace with the requirements of new UK and EU legislation. B&V Water took an innovative approach to turn stormwater management into a recreational park in Lenexa, Kansas, and offer communities globally a successful integrated stormwater strategy. As ...

  • Evaluation of stormwater BMPs for implementing industrial stormwater permitting strategy

    This study assesses the performance of stormwater best management practices (BMPs) in industrial sectors and their effluent quality to facilitate the development of technology-based numerical effluent criteria. Generally, retention ponds outperform other BMP types for reducing total suspended solids, and media filter and wetland basins outperform other BMPs for metal removal. Detention basins ...

  • Stormwater Solids Reduction for NPDES Permits

    Finally obtaining a National Pollution Discharge Elimination System (NPDES) Permit is often a relief but is by far not the end of the story. Meeting the requirements of that permit often proves to be quite difficult and stiff fines are freely doled out to those who fail to meet regulatory limits. For one Midwest jet propulsion manufacturing facility, the issue of total daily solids discharge ...

  • Performance of a pilot-scale constructed wetland for stormwater runoff and domestic sewage treatment on the banks of a polluted urban river

    To examine the performance of a constructed wetland system on stormwater runoff and domestic sewage (SRS) treatment in central east China, two parallel pilot-scale integrated constructed wetland (ICW) systems were operated for one year. Each ICW consisted of a down-flow bed, an up-flow bed and a horizontal subsurface flow bed. The average removal rates of chemical oxygen demand (CODCr), total ...
