  • 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. ...

  • 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, ...

  • Balancing growth and conservation - Precast concrete manholes become part of the stormwater solution

    When American Fork, Utah, decided to approve construction of a 175-acre commercial center, the city engineers had to consider the environmental effect it would have on a 45-acre wetland right next door. Under the EPA´s Phase II Storm Water Rules, adapted in late 1999, almost any city large enough to require a storm sewer system must balance growth with the environmental impacts of ...

  • Innovative use of lamella clarifiers for central stormwater treatment in separate sewer systems

    Lamella settlers have been used in the past few years for the sedimentation of particles in wastewater and stormwater applications. A new and very innovative approach for the treatment of stormwater flows is proposed which extends the portfolio of solutions beyond traditional settling tanks. Surface runoff is stored in a sewer or a basin and finally treated in a small but continuously operated ...

  • 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 ...

  • New option for stormwater treatment maximizes usable land area for redevelopment

    Untitled Document In June 2002, First Independent Bank of Vancouver, Wash., began construction on its 15,000 square-foot First Investments Plaza office complex. The ...


  • Monitoring fuels in Stormwater - Case study

    The Situation A major pipeline company has large storage tank farms throughout the Western States. The pipeline company transports, stores, blends additives, and distributes gasoline, diesel, and jet fuel to retail service stations and airports. Due to the quantity and movement of fuel at these facilities, there is always the potential for fuel spills. These facilities prevent out of ...

  • Lake Lenexa Stormwater Management Project

    Using cutting-edge technologies to significantly upgrade wastewater treatment in coastal areas, B&V Water helped Southern Water keep pace with the requirements of new UK and EU legislation. B&V Water took an innovative approach to turn stormwater management into a recreational park in Lenexa, Kansas, and offer communities globally a successful integrated stormwater strategy. As ...

  • Reuse turns stormwater runoff from a problem to an asset

    With so much concern about water scarcity around the world, it seems a no-brainer that rain is a good thing. But nothing’s perfect. Even something as beneficial as precipitation can have its downsides. One problem, of course, is flooding. Another problem you may not have thought of comes with stormwater runoff in urban settings. What’s the problem? In cities, buildings and pavement ...

  • 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 ...

  • 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 ...

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

  • Mononov provides stormscreen solution to sewage problem

    The installation of a Mono Stormscreen unit now allows the incoming raw sewage to be thoroughly screened at storm level, ensuring large solids are retained in the main flow to treatment and that the stormwater discharge from inlet meets consent requirements. The Stormscreen is designed to provide a self-cleaning, self-powered alternative to existing mesh screens for handling storm overflows. ...

  • Wallingford solutions enable an integrated approach to modeling

    Of the many advantages to Wallingford Software’s InfoWorks suite of solutions, one that is particularly valued in today’s demanding modeling environment is their reputation as the gold standard for integration. The solutions allow one interface to answer a wide range of questions, rather than requiring a user to laboriously work through a range of modules or packages. Such key but separate ...

  • Log yard water treatment study - Case Study

    Stormwater run-off from log yards and saw mills has long been a difficult waste stream to manage. The challenge arises from ability of wood and bark to easily leach high levels of organics (tannins, lignins, phenolics and resin acids) into mobile water. These organics can remain in the suspended state for months and exhibit toxicity to aquatic life as organisms break them down leading to a ...

  • Wetlands for Industrial Wastewater Treatment at the Savannah River Site

    ABSTRACT The A-01 effluent outfall, which collects both normal daily process flow and stormwater runoff from a industrial research facility, did not meet the South Carolina Department of Health and Environmental Control (SCDHEC) National Pollutant Discharge Elimination System (NPDES) permit limits for metals, toxicity, and total residual chlorine at the outfall sampling point. Copper was the ...
