  • 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 ...

  • 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 ...

  • 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. ...

  • 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 ...

  • Super Size My Stormwater Treatment System, Please!

    Many municipalities have vast areas of developed impervious acreage from which stormwater drains without any form of treatment. These drainage systems were designed decades ago, predating regulatory requirement for nonpoint source pollution control. Every year pollutants from these sites discharge high levels of sediment, nutrients, trash, and heavy metals into local waters, impairing usage, ...

  • 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 ...

  • 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 ...

  • 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 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: 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 ...

  • The world`s largest stormwater alum treatment facility - in Florida

    Stormwater in the Florida canal system is slow moving.  The green, murky water in the lakes fed by the Apopka-Beauclair canal is caused by an overabundance of algae-feeding compounds, mainly phosphorus, resulting in chronic algal blooms.  The Nutrient Reduction Facility (NuRF) project designed a system to inject aluminum sulface (alum) into the nutrient-laden water in direct proportion ...

  • New option for stormwater treatment maximizes usable land area for redevelopment

    Untitled Document In June 2002, First Independent Bank of Vancouver, Wash., began construction on its 15,000 square-foot First Investments Plaza office complex. The ...


  • 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 ...

  • 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 ...

  • About Everglades construction project

    The Everglades is a one-of-a-kind habitat, the largest wetland and subtropical wilderness in the United States. For more than 100 years, the ecosystem has suffered at the hands of man, with agriculture encroachment and development runoff disrupting native plants and animals. For more than 25 years the South Florida Water Management District has been investigating ways to restore and protect the ...

  • Bioswales reduce contaminants associated with toxicity in urban stormwater

    Contamination and toxicity associated with urban stormwater runoff are a growing concern because of the potential for receiving system impacts. California water regulators are mandating implementation of green infrastructure as part of new urban development projects to treat stormwater and increase infiltration. Parking lot bioswales are low impact development practices that promote filtering ...

  • Passive Filter – Sustainable BMP For Permanent Stormwater Treatment Of Heavy Metals, Nutrients, Hydrocarbons And Sediment

    Passive filtration provides a sustainable alternative to classical drainage concepts for source control of hydrocarbons, heavy metals and nutrients that endanger our water bodies. In urban areas with high building density, traditional drainage concepts like wetlands are not available and the concept of decentralized treatment facilities that can be housed in catch basin structures are a viable ...

  • Evaluation of undersized bioretention stormwater control measures for treatment of highway bridge deck runoff

    Two grassed bioretention cells were constructed in the easement of a bridge deck in Knightdale, North Carolina, USA, in October, 2009. One was intentionally undersized (‘small’), while the other was full sized (‘large’) per current North Carolina standards. The large and small cells captured runoff from the 25- and 8-mm events, respectively. Both bioretention cells employed average fill media ...
