  • Exploring fecal indicator bacteria in a constructed stormwater wetland

    Microbial pollution in surface waters is a concern throughout the world, with both public health and economic implications. One contributing source to such pollution is stormwater runoff, often treated using various types of stormwater control measures. However, relatively little is known regarding microbe sequestration in constructed stormwater wetlands (CSWs), one type of commonly installed ...

  • 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 ...

  • 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 ...

  • Comparison of the treatment performance of hybrid constructed wetlands treating stormwater runoff

    This study was conducted to compare the treatment performance of two hybrid constructed wetlands (CWs) in treating stormwater runoff. The hybrid CWs were composed of a combination of free water surface (FWS) and horizontal subsurface flow (HSSF) CWs. Based on the results, strong correlation exists between potential runoff impacts and stormwater characteristics; however, the low correlations ...

  • Particle retention in compact constructed wetlands treating highway stormwater

    Three pilot-scale compact constructed wetland systems were constructed to treat stormwater from a highway. They each comprised a sedimentation tank, and a vertical flow (VF) wetland bed equipped with a recirculation device. The VF wetland beds were filled with woodchip, pumice and volcanic gravel, respectively. According to the analysis of the particle size distributions (0.52–500 ...

  • 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 ...

  • Stormwater treatment area 3/4

    Restore the Everglades That's the task the Florida Legislature set for the South Florida Water Management District. But how? Decades of development had eliminated the sheet flow of water from Lake Okeechobee. Densely populated cities and a 700,000-acre agricultural area, drained by 1,500 miles of canals and levees, now lay between the lake and the Everglades. Wetlands have disappeared. ...

  • 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 ...

  • 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 ...

  • Experience with Local Stormwater Management Programs

     ABSTRACT Local stormwater management programs have traditionally been operated and funded as a function of general government. Increasing requirements to deal with wet weather water quality problems and the devastating impact of flooding have led to increased efforts to expand organizational responsibilities and the need for new and dedicated funding. To provide a cross section of ...

  • 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 ...

  • Pathogen inactivation during passage of stormwater through a constructed reedbed and aquifer transfer, storage and recovery

    A study was undertaken to determine the potential inactivation rates of selected enteric microorganisms in captured urban stormwater within a constructed reedbed and in tertiary carbonated aquifer during an Aquifer Storage, Transfer and Recovery (ASTR) scheme. The study was undertaken in-situ in the constructed reedbed and aquifer using diffusion chambers. The results showed that all tested ...
