Stormwater Management Case Studies and White Papers

  1. Stormwater Management - Cog Moors Wastewater Treatment Works, South Wales (Case Study)

    Wales is said to be wetter throughout the year than Northern Ireland and England, and is known for intense rainfall activity. Therefore, effectively treating and managing the country’s substantial stormwater runoff is of utmost importance. It’s also subject to increased scrutiny from governing bodies.

  2. White Paper: Stormwater Retention For A Modular Green Roof Using Energy Balance Data
    New York City stormwater is a major cause of water pollution in the harbor and estuaries. This is due to the vast areas of impervious surfaces (e.g., rooftops, pavements, sidewalks) that rapidly shunt runoff into the combined sewage overflow (CSO) system.
  3. The Value Of Green Infrastructure: A Guide To Recognizing Its Economic, Social, And Environmental Benefits
    “The Value of Green Infrastructure” provides a framework to help communities measure and value the air quality, energy use, and many other benefits that green infrastructure provides. It allows communities to more accurately compare different infrastructure investments and choose the option that provides the greatest long-term benefit. By American Rivers
  4. Improving Water System Performance: A Continuous TOC Measurement Technology To Enhance Real-Time Process Control
    This article discusses real-time Total Organic Carbon (TOC) tracking in the water purification process and the importance of rapid, continuous, and reliable TOC monitoring for real-time critical water release. Submitted by Mettler-Toledo Thornton
  5. JWC’s Honey Monster Helps Big Fish Environmental Find Clean Water

    For several years, local Michigan municipalities were overloaded with septage disposal issues and it was difficult for private pumpers to offload as land-application of septage became illegal. So John Campbell, founder of Big Fish Environmental and a 29-year veteran of septic tank pumping, started developing a unique and efficient septage receiving and treatment plant design.

  6. White Paper: Challenging Urban BMP Assumptions
    There are two broad classifications of structural Best Management Practices (BMPs). This paper is concerned with devices or techniques that are intended to capture and hold materials that can be separated by gravity, buoyancy, screening, and skimming. By John Moll, CEO, CrystalStream Technologies
  7. Case Study: CST Handles Combined Sewer Pre-Treatment For City Of San Francisco
    The San Francisco Department of Public Works required a cost-effective solution to pre-treat the downstream lift station system from trash, debris, vegetative material, and primarily sediment, which was destroying grinder pumps and occluding the downstream conveyance pipes at a huge cost to the city. By CrystalStream Technologies
  8. White Paper: Sustainable Water Systems: Step One — Redefining The Nation's Infrastructure Challenge

    America’s drinking water and wastewater systems face increasing challenges in maintaining and replacing their pipes, treatment plants, and other critical infrastructure. Prolonging and renewing the nation’s high-quality water services requires a clear sense of what is a sustainable water infrastructure, the amount of investment needed to create and preserve it, where investments should be made, and by whom. In 2008 and 2009 the Aspen Institute convened a multi-stakeholder dialogue to help provide clarity and promote leadership on these issues. By The Aspen Institute

  9. White Paper: What Happens After The BMP Is Installed?
    The demand for stormwater treatment is rising at an increasingly accelerated rate as EPA regulatory demands become more stringent. These regulations have paved the way for emerging technologies to meet environmental needs. With new product developments comes the need for testing and performance verification. Once the demands for verification are met and local regulatory agencies have accepted the practice, these practices can start to be specified and installed to help clean our stormwater runoff. But we should be asking ourselves a series of other questions. By Jeffrey Benty and Dino Pezzimenti
  10. What Happens After The BMP Is Installed?
    The demand for stormwater treatment is rising at an increasingly accelerated rate as the Environmental Protection Agency Regulatory demands become more stringent. These regulations have provided the way for emerging technologies to meet the environmental needs, from Land Based to proprietary products. By Jeffrey Benty & Dino Pezzimenti
