  • Micro-zooplankton grazing as a means of fecal bacteria removal in stormwater BMPs

    A priority for environmental managers is control of stormwater runoff pollution, especially fecal microbial pollution. This research was designed to determine if fecal bacterial grazing by micro-zooplankton is a significant control on fecal bacteria in aquatic best management practices (BMPs); if grazing differs between a wet detention pond and a constructed wetland; and if environmental ...

  • Structural improvements on hydrodynamic separators: a computational fluid dynamics approach

    Hydrodynamic separators (HDSs) have been used extensively to reduce stormwater pollutants from urbanized areas before entering the receiving water bodies. They primarily remove particulates and associated pollutants using gravity settling. Two types of HDSs with different structural configurations of the inner vortex-inducing components were presented in this study. One configuration consisted ...

  • 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 ...

  • Effect of sampling duration on the performance evaluation of a stormwater wetland

    In this study, the effect of sampling duration on the performance estimate for a stormwater wetland over both rainy and dry days was evaluated for the appropriate design of sampling duration. As the cumulative percentage volume (Vp), the ratio of cumulative stormwater volume concerning time to the total stormwater volume, varied between 60 and 100%, generally, the inflow total suspended ...

  • 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 ...

  • Modelling pathogen fate in stormwaters by a particle–pathogen interaction model using population balances

    Stormwater is polluted by various contaminants affecting the quality of receiving water bodies. Pathogens are one of these contaminants, which have a critical effect on water use in rivers. Increasing the retention time of water in stormwater basins can lead to reduced loads of pathogens released to the rivers. In this paper a model describing the behaviour of pathogens in stormwater basins is ...

  • 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 quality models: performance and sensitivity analysis

    The complex nature of pollutant accumulation and washoff, along with high temporal and spatial variations, pose challenges for the development and establishment of accurate and reliable models of the pollution generation process in urban environments. Therefore, the search for reliable stormwater quality models remains an important area of research. Model calibration and sensitivity analysis of ...

  • Determining water sensitive urban design project benefits using a multi-criteria assessment tool

    The integration of urban water cycle management with urban planning and design is referred to as ‘Water Sensitive Urban Design’ or ‘WSUD’ in Australia; one of the key elements of WSUD is the management of urban stormwater. In early 2006, the Victorian Government released the Yarra River Action Plan, which allocated $20 million towards tackling urban stormwater pollution. To help ensure this money ...

  • 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 ...

  • Reducing stormwater costs through low impact development (LID) strategies and practices

    This report summarizes 17 case studies of developments that include Low Impact Development (LID) practices and concludes that applying LID techniques can reduce project costs and improve environmental performance. In most cases, LID practices were shown to be both fiscally and environmentally beneficial to communities. In a few cases, LID project costs were higher than those for conventional ...

  • Low impact development: San Francisco’s green approach to stormwater management

     ABSTRACT This paper presents the methods, findings, and policy implications of a comprehensive evaluation of low impact development (LID) techniques for the City of San Francisco. LID is an innovative approach to stormwater management that relies on decentralized, small-scale stormwater facilities and site-design techniques to reduce wet weather flows and to remove stormwater ...

  • 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 ...

  • 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 ...

  • 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 ...
