  • How do you clean a stormwater management pond?

    How do you clean a stormwater management pond (SMWP) without draining the pond first? A clean-out of the SWMP is required once every 5-15 years to remove accumulated sediments to ensure the pond continues to function as intended. Drainage of the SWMP is not always required to facilitate the clean-out. By combining the pumping and excavation into one process! New pumping technology - Dragflow ...

  • Retrofitting a stormwater retention pond using a deflector island

    Stormwater retention ponds are one of the principal methods to treat stormwater runoff. Analysis of residence time distribution (RTD) curves can be used to evaluate the capability of these ponds for sediment removal. Deflector islands have been suggested as a means of improving the performance of retention ponds, due to their diffusing the inlet jet. In this study, the effect of an island on ...

  • Elimination and accumulation of polycyclic aromatic hydrocarbons in urban stormwater wet detention ponds

    The concentrations of polycyclic aromatic hydrocarbons (PAHs) in water and sediments of seven wet detention ponds receiving urban stormwater were investigated. The ponds comprised traditional wet detention ponds with a permanent wet volume and a storage volume as well as ponds that were expanded with sand filters and other means to improve the removal of micropollutants. The concentrations of ...

  • Heavy metals, PAHs and toxicity in stormwater wet detention ponds

    Concentrations of 6 different heavy metals and total polycyclic aromatic hydrocarbons (PAHs) were determined in stormwater runoff and in the pond water of two Danish wet detention ponds. The pond water samples were analyzed for toxic effects, using the algae Selenastrum capricornutum as a test organism. Stormwater and pond water from a catchment with light industry showed high levels of heavy ...

  • Seasonal size distributions of suspended solids in a stormwater management pond

    ABSTRACTThree seasonal surveys of suspended solids were carried out in an on-stream stormwater management pond, by means of a submersible laser particle size analyser. Size distributions were measured at up to 17 points in the pond, and water samples collected at the same locations were analysed for primary particles aggregated in flocs. Observed suspended solids were mostly composed of flocs, ...

  • 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 ...

  • Pilot plant study for one year: water quality management and algal control of sustainable urban stormwater ponds

    Pond structures as cost-effective "source control" drainage techniques that can be applied to reduce the risk of downstream flooding and to recycle stormwater. There are no widely accepted performance and water quality management data on stormwater ponds, yet there is a need for operation and maintenance guidelines, coupled with data on reliability, economics and public acceptance. The purpose of ...

  • In search of effective bioassessment of urban stormwater pond sediments: enhancing the ‘sediment quality triad’ approach with oligochaete metrics

    Stormwater ponds have been widely used to control increased volumes and rates of surface runoff resulting from urbanization. As receiving waters, they are under the influence of intermittent pollution from urban wet-weather discharges. Meanwhile they offer new aquatic habitats balancing the transformation of initial ecosystems and their associated biodiversity. Bioassessment of stormwater ...

  • GCL used in stormwater pond helps maintain natural habitat for local cutthroat trout

    PROJECT: Kearns Meadow Stormwater Pond LOCATION: Jackson, Wyoming PRODUCTS: BENTOMAT® CL BACKGROUND: Kearns Meadow consists of 41-acres of land in the middle of Jackson, Wyoming. It contains approximately one mile of Flat Creek, which serves as an important spawning habitat for local cutthroat trout. ...

  • Tropical stormwater nutrient degradation using nano-TiO2 in photocatalytic reactor detention pond

    The photo-degradation of nutrients in stormwater in photocatalytic reactor wet detention pond using nano titanium dioxide (TiO2) in concrete was investigated in a scale model as a new stormwater treatment method. Degradation of phosphate and nitrate in the presence of nano-TiO2 under natural ultra violet (UV) from tropical sunlight was monitored for 3 weeks compared with normal ponds. ...

  • 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 ...

  • Modeling of Sedimentation in Stormwater Detention Basins

    ABSTRACTTo minimize the non-point source pollution from roadway surface, the Texas Department of Transportation (TxDOT) initiated a research project for design of a small footprint non-proprietary detention basin, which consists of pipes and box culvert sections with specialized inlet and outlet system. A conceptual model was developed to estimate particle removal efficiency of the rectangular ...

  • 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 ...

  • 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 ...

  • Benefits of a BaySaver Separation System for Wet Pond Pretreatment

    There are instances when a BaySaver Separation System may be used as a pretreatment device for a wet pond; when environmental regulations require it; or when a stand alone physical separator is not enough to meet an 80% removal efficiency using solely this product. There are cost benefits associated with using BaySaver products in conjunction with other Best Management Practices (BMPs). In the ...

  • Stormwater Solids Reduction for NPDES Permits

    Finally obtaining a National Pollution Discharge Elimination System (NPDES) Permit is often a relief but is by far not the end of the story. Meeting the requirements of that permit often proves to be quite difficult and stiff fines are freely doled out to those who fail to meet regulatory limits. For one Midwest jet propulsion manufacturing facility, the issue of total daily solids discharge ...

  • Stormwater nitrogen removal performance of a floating treatment wetland

    The nitrogen (N) removal efficiency and effluent quality of two parallel stormwater retention ponds, one retrofitted with a floating treatment wetland (FTW) and one without any vegetation, was compared in a field trial. This study shows that inclusion of FTWs in stormwater retention ponds has potential to moderately improve N removal. Median FTW outlet event mean concentrations (EMCs) were lower ...

  • Permeable Pavers Provide Pavement and Stormwater Solutions

    Creating new life to a small, historic park included installing massive playground equipment and more parking. Asphalt was not a slam dunk for parking since there wasn’t room for more paving and a detention pond. Indianapolis-based landscape architect Debra Schmucker, president of Cornerstone Planning & Design, was commissioned by the city to draw up plans for the revitalized park found the ...
