  • Hirschthal, Switzerland protected with WaStop DN1200 - Case Study

    Location: Hirschthal, Switzerland Problem: During times of high river levels, flooding occurred in the town of Hirschthal. This flooding occurred when the river level was higher than the stormwater outfall. This lead to river water pushing back up the outfall pipe, and spilling onto roads and residential areas. Solution: A DN1200 (NPS 48″) ...

  • Monitoring micropollutants in the Swist river basin

    Micropollutant pathways were studied for the Swist river basin (Western Germany). The aim was to verify the effectiveness of a monitoring approach to detect micropollutants entering the river. In a separate sewer system, water was frequently found to be contaminated with micropollutants. Improper connections of sewage canals to the stormwater network seemed to be the cause of pollution. ...

  • Silt Fence installation efficacy: definitive research calls for toughening specifications and introducing new technology

    Introduction: Silt fence is a joke on many construction sites. It is often seen just blowing in the wind, or sagging and broken down. Some specifiers won’t utilize silt fence on their sites because it is too often installed improperly, and not maintained. Yet, the need for effective on-site sediment control has never been greater. Sediment-laden runoff has been shown to result in the loss ...

  • Discussion about initial runoff and volume capture ratio of annual rainfall

    In recent years, runoff pollution from urban areas has become a major concern all over the world. But there exists a worldwide confusion about how much stormwater should be captured for the purpose of runoff pollution control. Furthermore, the construction cost and pollution control efficiency are closely linked with the size of stormwater facilities, which is then related to the first flush ...

  • 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™ ...

  • Spatial and temporal variation of fecal indicator organisms in two creeks in Beltsville, Maryland

    Evaluation of microbial water quality is commonly based on monitoring populations of fecal indicator organisms (FIO) such as Escherichia coli (EC) and enterococci (ENT). The occurrence of elevated FIO concentrations in surface waters after storm events is well documented and has been attributed to runoff and sediment resuspension. The reasons for FIO concentration variation under baseflow ...
