  • Innovative technologies for management of stormwater and combined sewer flows

    Stormwater flows have historically been considered as harmless. Studies have shown that these flows cannot be dismissed as easily. Chebbo (1992), Marsalek et al.,(1997) and others have shown that stormwater is a source of diffuse pollution with a high source of total suspended solids (TSS), adsorbed hydrocarbons (HC) and nutrient loads (N, P, etc..). All these factors influence the quality of the ...

  • Reusing Greywater and Stormwater in California

  • Paving Success with Stormwater

    Chuck Taylor lives for rain. Sure, he’s heard the comments about not having enough sense about his habit of standing outside during a downpour. His preference for rain isn’t that this contractor enjoys the smell of wet clothing. Taylor’s fascination with inclement weather comes from the satisfaction while seeing his company’s workmanship ...

  • 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. ...

  • 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 ...

  • 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 ...


  • LEED-ing Your Stormwater Down the Green Path

    6813The U.S. Green Building Council has developed the Leadership in Energy and Environmental Design, otherwise known as LEED. This program is a national standard for #28;green building#29; design and was developed with the intention of improving occupant well-being, environmental performance and economic returns. This is accomplished by using innovative design practices and technologies. In order ...

  • 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 ...

  • Stormwater and Spill Management at an Iron Pipe Foundry in Texas

    ABSTRACTLarge industrial sites have had permits for storm water discharges under the NPDES program of the Clean Water Act since the mid to late 80’s. Recent emphasis has been placed on regulated facilities to prepare and implement Spill Prevention, Control and Countermeasure (SPCC) plans under the Oil Pollution Prevention Act (40 CFR 112). A large iron pipe foundry in Texas has several storm ...

  • Inclined Plate Settlers to Treat Stormwater Solids

    ABSTRACTIt has been well-documented that, in stormwater runoff, many of the problem pollutants are associated with the particulate fraction. Past characterization of urban runoff and source contributions has shown the following: (a) soil disturbance increased the TSS and turbidity in the runoff; and (b) correlations were observed between TSS and particulate runoff concentrations of chromium, ...

  • 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, ...

  • 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 ...

  • Cost-Benefit Analysis of Urban Stormwater Retrofits and Stream Daylighting Using Low Impact Development Technologies

    ABSTRACTThis project incorporates Low Impact Development (LID) concepts into the City of Caldwell (Idaho) Indian Creek daylighting and downtown redevelopment project, which is a prime candidate for a “showcase” project producing benefits in urban runoff within the lower Boise River watershed. The primary goal of this project was to incorporate LID concepts into the Indian Creek daylighting ...

  • 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 ...

  • Enlightenment from ancient Chinese urban and rural stormwater management practices

    Hundreds of years ago, the ancient Chinese implemented several outstanding projects to cope with the changing climate and violent floods. Some of these projects are still in use today. These projects evolved from the experience and knowledge accumulated through the long coexistence of people with nature. The concepts behind these ancient stormwater management practices, such as low-impact ...
