  • 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 ...

  • Modeled Flow Duration Variations, Pollutant Discharges, and Costs for Different Stormwater Controls

    ABSTRACTRunoff volume and pollutant discharges increase with development, with associated detrimental receiving water effects. These increases can be partially controlled by installing stormwater control practices, such as wet detention pond at outfalls, using conservation design controls such as grass swales and bioretention devices, and by improved development practices that reduce the amounts ...

  • 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 ...

  • Warning! Beware stormwater product

    Warning! Beware of a storm water insert sold under the trade mark "Safe Drain".  This product holds water in the open position.  Standing water can present both odor and health issues.  In 2004, Cameron M. Colson patented a leading storm water drain insert that utilized a butterfly valve mounted inside the storm water insert that aided in spill control.  This Design was ...

  • The urban stormwater farm

    Currently more than 3 billion people live in urban areas. The urban population is predicted to increase by a further 3 billion by 2,050. Rising oil prices, unreliable rainfall and natural disasters have all contributed to a rise in global food prices. Food security is becoming an increasingly important issue for many nations. There is also a growing awareness of both ‘food miles’ and ‘virtual ...

  • 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 ...

  • The 7 Tips for Highly Effective Stormwater Management By-Laws

    ABSTRACT The Stormwater Phase II Final Rule, which applies to small municipal separate storm sewer systems (MS4s) in “urbanized areas”, requires communities across the country to adopt local legislation that will control the harmful effects of stormwater runoff and prohibit non-stormwater pollution from entering the drainage system. Adopting a thoughtful and comprehensive stormwater by-law ...

  • The impact of intentional stormwater infiltration on soil and groundwater

    ABSTRACTStormwater infiltration is a principle which is more and more utilized on urban sites in France. However, given the characteristics of urban surfaces, and notably the amounts of the different pollutants that stormwater is likely to contain, it is important to try to assess the impact of intentional stormwater infiltration systems on the soil, and on groundwater. To try to answer that ...

  • Alternatives for Finding Illicit Discharges to Stormwater Systems

    ABSTRACT Provisions of the National Pollutant Discharge Elimination System (NPDES) permits for stormwater discharges require that permits for municipal separate storm sewers systems (MS4s) shall include a requirement to effectively prohibit problematic non-storm water discharges into storm sewers. Emphasis is placed on the elimination of inappropriateconnections to urban storm drains. ...

  • Measuring the Effectiveness of Watershed-Based General Stormwater Permitting

    ABSTRACTThe U.S. EPA and most water resources professionals advocate holistic and adaptive watershed management approaches to the protection and restoration of aquatic ecosystems by encouraging pollution control strategies that are developed through collaborative partnerships within a hydrologic boundary. This paper evaluates the effectiveness of the holistic adaptive management approach through ...

  • Washington State DOE stormwater report - Case Study

    Fitesa, a non-wovens manufacturer in the state of Washington consistently tests stormwater but experienced problems meeting the stormwater standards for zinc and copper discharge. Zinc is used in galvanized metal, shingles, finishes in paints, and car tires—zinc iseverywhere. Copper is used in items such as in brake linings and pressure treated lumber. At sites near heavily traveled roads, ...

  • 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 ...

  • How to Plan Stormwater Management for Urban Areas

    Water is a vital commodity in our lives, but it is possible to have too much water all at once in our lives, especially following violent storms or snow melt. This excess water, lying on the ground, swelling rivers, canals and drains to over-capacity is known as stormwater. In order to make the best use of this water, local authorities need to safely contain stormwater while any ...

  • 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 ...

  • New strategies in stormwater-meltwater management in the city of Bergen, Norway

    ABSTRACTIn the City of Bergen, Norway, extensive measures against point pollution sources are now to be implemented and to be finished before the end of year 2000, improving the receiving water conditions. Local politicians and public opinion support high standards of receiving water, even higher than the national level. Future improvements in the receiving water quality is planned through ...

  • Developing a Stormwater Infrastructure Geospatial Database for a Large Non-Traditional MS4 System

     ABSTRACT The Massachusetts Department of Conservation and Recreation (DCR) is a state agency which owns and maintains parks, conservation and watershed land, and roadways. They are regulated as a non-traditional MS4 stormwater municipality under the U.S. Environmental Protection Agency’s (EPA) National Pollutant Discharge Elimination System (NPDES) Phase II program. To satisfy the ...

  • Low impact development: San Francisco’s green approach to stormwater management

    This paper presents the methods, findings, and policy implications of a comprehensive evaluation of low impact development (LID) techniques for the City of San Francisco.

The LID analysis ...

  • 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 ...
