  • 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 ...

  • 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 ...


  • A Comparison of Two Media Filtration BMP Treatments for the Removal of PAHS and Phthalates from Roadway Runoff

    Urban runoff is a major contributor to the degradation of our urban streams, rivers, and lakes (Pitt, 1995). Organic pollutants, such as PAHs and phthalates, in urban stormwater can contribute to receiving water degradation (EPA, 1983). A study in Rhode Island’s Narragansett Bay watershed found that urban runoff accounted for 71 percent of the total inputs to the bay for higher molecular weight ...


  • A Comprehesive Approach to Performance Verification for Stormwater Treatment Systems

    In recent years, there have been several attempts to standardize field testing protocols to address the difficulty of comparing the performance of different stormwater treatment technologies tested under disparate field conditions and protocols. Following these protocols will enable a direct evaluation of a particular best management practice’s (BMP) ability to capture a specific pollutant load ...


  • 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, ...

  • 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 ...

  • Modeling BMP’s in Sensitive Areas with xpswmm - King’s Beach Watershed Improvement Project - Case Study

    Introduction Located on the border of California and Nevada, Lake Tahoe (the Lake) is the largest alpine lake in North America. It is known for its scenic beauty and outstanding lake clarity. However, the clarity of the Lake has been declining since the mid-1960s because of the deposition of fine particles and nutrients from urban runoff and the growth of aquatic organisms that feed off the ...

  • Retrofitting an Existing Stormwater System to Meet Numerical Effluent Limits - Stormwater Management at Seattle-Tacoma International Airport

    ABSTRACTOwned and operated by the Port of Seattle, Seattle-Tacoma International Airport (STIA) is the 28th busiest airport in the world. A Section 401 Water Quality Certification was issued to the Port to allow its expansion projects to proceed. This certification required existing portions of the airport be retrofitted to meet current stormwater standards. In addition, the Port’s renewed NPDES ...

  • Evironmentally Concious Stormwater Management Through Sustainable Design and Best Management Practices

    ABSTRACTBecause development has dramatically altered the hydrologic environment’s sustainability, the Milwaukee Metropolitan Sewerage District (MMSD) is encouraging the use of “green” design through stormwater management BMPs. The MMSD asked Graef, Anhalt, Schloemer and Associates, Inc. (GAS) to evaluate and design stormwater management BMPs. The MMSD headquarters in Milwaukee, WI is serving as ...

  • CFD modelling of flow field and particle tracking in a hydrodynamic stormwater separator

    The best management practices (BMPs) for control of urban stormwater pollution are evaluated to remove solid particles containing various pollutants. Currently, most storm runoff treatment devices using primary pollutant removal mechanism are applied to storm water since most pollutants in runoff are associated with the solid particulates. A hydrodynamic separator is a storm water treatment ...

  • Whittier in Frederick, Maryland - Storm Water Treatment Underground Systems Meet Regulatory Requirements

    The Assisted Living Project at Whittier in Frederick, M.D. is a 6.3 acre retirement community situated next to Whittier Lake. Planned by Fox & Associates, it included special design considerations for a cost-effective and attractive means of treating stormwater. To detail the Whittier site, it is comprised of a retirement assisted living facility which is 19,151 sq. ft., a retirement medical ...

  • How a LEED Platinum Building is Cleaning up Inland Empire Urban Runoff

    ABSTRACTIn 2002, the Inland Empire Utility Agency (IEUA) – a municipal water agency in western San Bernardino County - designed and constructed its new Headquarters with the goal of attaining the first 2.0 platinum level “LEED” - Leadership in Energy and Environmental Design - rating established by the U. S. Green Building Council.” IEUA has implemented a BMP project that truly showcases the ...

  • Specify the BaySaver® XK for High Flow Storms!

    The patented BaySaver XK Separation System can be sized to treat any flow rate. The system was designed to effectively and economically remove sediment, petroleum hydrocarbons, and gross debris. Since every BaySaver XK Stormwater Separation System is custom designed, specific non-dissolved pollutants can be targeted by changing system components. Using the same technology and principles that are ...

  • City of Santa Monica Airport Watershed Management Plan

     ABSTRACT The City of Santa Monica implements best management practices (BMPs) to address urban stormwater runoff and uses a “hierarchy” of BMPs to prioritize implementation based on the principles of protecting public safety and the environment, maximizing environmental benefits, and minimizing costs. The hierarchy of BMPs includes the following (in order of priority): 1) harvesting, ...

  • 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 ...

  • Erosion and Sediment Control: Navigating NPDES Regulations, the SWPPP, and Techniques for Compliance

    Erosion and Sedimentation: Why Are They a Problem? The US Environmental Protection Agency lists sediment as the single most common pollutant in rivers, streams, lakes, and reservoirs. With all the potentially harmful chemicals and substances in the world, it seems odd to many people that sediment—dirt, essentially—is singled out as the major culprit. Yet these particles of ...
