  • 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 ...

  • Productivity Gains in Stormwater Design

    For some engineering consultants, traditional stormwater pond design can be one of the most frequent projects within their services portfolio. An engineer with prior experience can size and produce plans with assistance from modeling software, AutoCAD, and supporting tools with relative ease. But even very routine projects can benefit from modeling software improvements. McBade Engineers and ...

  • Trends in rainfall intensity for stormwater designs in Ontario

    The intensities of short-duration rainfall events are fundamental inputs to the design of stormwater management infrastructure. However, since stormwater infrastructure must function as designed for many decades, if there are long-term trends in rainfall intensities, design storms need to be modified. Evidence demonstrates, using data from 13 rain gauges in Ontario, that storm intensities ...

  • Synergistic benefits between stormwater management measures and a new pricing system for stormwater in the City of Hamburg

    Hamburg is a growing metropolitan city. The increase in sealed surfaces of about 0.36% per year and the subsequent increased runoff impacts on the city's wastewater infrastructure. Further potential risks to the drainage infrastructure arise also from effects of climate change, e.g. increased intensity and frequency of heavy rainfalls. These challenges were addressed in the Rain InfraStructure ...

  • Model-based monitoring of stormwater runoff quality

    Monitoring of micropollutants (MP) in stormwater is essential to evaluate the impacts of stormwater on the receiving aquatic environment. The aim of this study was to investigate how different strategies for monitoring of stormwater quality (combining a model with field sampling) affect the information obtained about MP discharged from the monitored system. A dynamic stormwater quality model was ...

  • 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 ...

  • Sensitivity analysis of an urban stormwater microorganism model

    This paper presents the sensitivity analysis of a newly developed model which predicts microorganism concentrations in urban stormwater (MOPUS—MicroOrganism Prediction in Urban Stormwater). The analysis used Escherichia coli data collected from four urban catchments in Melbourne, Australia. The MICA program (Model Independent Markov Chain Monte Carlo Analysis), used to conduct this analysis, ...

  • Calibration of stormwater quality regression models: a random process?

    Regression models are among the most frequently used models to estimate pollutants event mean concentrations (EMC) in wet weather discharges in urban catchments. Two main questions dealing with the calibration of EMC regression models are investigated: i) the sensitivity of models to the size and the content of data sets used for their calibration, ii) the change of modelling results when models ...

  • The impact of intentional stormwater infiltration on soil and groundwater

    ABSTRACTStormwater infiltration is a principle which is more and more utilized on urban sites in France. However, given the characteristics of urban surfaces, and notably the amounts of the different pollutants that stormwater is likely to contain, it is important to try to assess the impact of intentional stormwater infiltration systems on the soil, and on groundwater. To try to answer that ...

  • Infiltration Study Poses Challenges But Could Save Millions on Treatment Plant

    Lower 48 Instruments works in partnership with consulting engineers to provide equipment and manpower for flow studies. IBI Group, out of Columbus, OH, USA, contracted with the company to provide placement expertise, equipment and data collection for a period of 60 days. Lower 48 installed 16 meters across the combined sewer district collection system to measure flow as well as rainfall-event ...

  • Preliminary stabilisation of stormwater biofilters and loss of filter material

    Stabilisation affects performance of stormwater biofilters operating under intermittent wetting and drying, mainly due to wash-off of filter material. Understanding the dynamics of solids wash-off is crucial in designing stormwater biofilters. The current study analysed the dynamics of solids wash-off in stormwater biofilters and quantified the loss of solids from the filter. Four Perspex™ ...

  • Inclined Plate Settlers to Treat Stormwater Solids

    ABSTRACTIt has been well-documented that, in stormwater runoff, many of the problem pollutants are associated with the particulate fraction. Past characterization of urban runoff and source contributions has shown the following: (a) soil disturbance increased the TSS and turbidity in the runoff; and (b) correlations were observed between TSS and particulate runoff concentrations of chromium, ...

  • Linking Data, Public Outreach and Education: A Local and Regional Collaborative – Lakesuperiorstreams.Org

    The City of Duluth, the University of Minnesota-Duluth (Natural Resources Research Institute and Minnesota Sea Grant) and other regional partners collaborated to develop Lakesuperiorstreams.org, a website that utilizes real time data (temperature, flow, precipitation, turbidity, specific conductivity) in an easy to understand animated graphical format to educate the public about (1) how streams ...

  • Real-Time Stormwater Management Using Depth, Duration, Frequency Thresholds

    ABSTRACTThe City of Austin (City) operates a Flood Early Warning System (FEWS) to reduce public exposure to flash flood hazards. The system is operated and maintained by the Watershed Protection and Development Review Department, Watershed Engineering Division. Advanced information and warning of urban storm water flooding is achieved by the FEWS. A critical component of the system is rainfall ...

  • Modelling of percolation rate of stormwater from underground infiltration systems

    Underground or surface stormwater storage tank systems that enable the infiltration of water into the ground are basic elements used in Sustainable Urban Drainage Systems (SUDS). So far, the design methods for such facilities have not taken into account the phenomenon of ground clogging during stormwater infiltration. Top layer sealing of the filter bed influences the infiltration rate of water ...

  • Measuring the Effectiveness of Watershed-Based General Stormwater Permitting

    ABSTRACTThe U.S. EPA and most water resources professionals advocate holistic and adaptive watershed management approaches to the protection and restoration of aquatic ecosystems by encouraging pollution control strategies that are developed through collaborative partnerships within a hydrologic boundary. This paper evaluates the effectiveness of the holistic adaptive management approach through ...

  • Characterization and source identification of stormwater runoff in tropical urban catchments

    The characteristics of urban stormwater pollution in the tropics are still poorly understood. This issue is crucial to the tropical environment because its rainfall and runoff generation processes are so different from temperate regions. In this regard, a stormwater monitoring program was carried out at three urban catchments (e.g. residential, commercial and industrial) in the southern part of ...
