  • 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. ...

  • Experience with Local Stormwater Management Programs

     ABSTRACT Local stormwater management programs have traditionally been operated and funded as a function of general government. Increasing requirements to deal with wet weather water quality problems and the devastating impact of flooding have led to increased efforts to expand organizational responsibilities and the need for new and dedicated funding. To provide a cross section of ...

  • 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 ...

  • Stormwater Solids Reduction for NPDES Permits

    Finally obtaining a National Pollution Discharge Elimination System (NPDES) Permit is often a relief but is by far not the end of the story. Meeting the requirements of that permit often proves to be quite difficult and stiff fines are freely doled out to those who fail to meet regulatory limits. For one Midwest jet propulsion manufacturing facility, the issue of total daily solids discharge ...

  • Infiltration Study Poses Challenges But Could Save Millions on Treatment Plant

    Lower 48 Instruments works in partnership with consulting engineers to provide equipment and manpower for flow studies. IBI Group, out of Columbus, OH, USA, contracted with the company to provide placement expertise, equipment and data collection for a period of 60 days. Lower 48 installed 16 meters across the combined sewer district collection system to measure flow as well as rainfall-event ...

  • 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, ...

  • Banner Bank Building – A Leader in Urban Stormwater and Graywater Reuse

    Urban stormwater runoff poses unique challenges to city planners, civil engineers and property owners. As designers seek better strategies to protect watersheds from contaminated urban runoff they are also faced with pressure to reduce costs while increasing capacity. Sustainable design strategies are proving that urban stormwater rates and quantities can be reduced while improving water quality. ...

  • 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 ...

  • Real-Time Stormwater Management Using Depth, Duration, Frequency Thresholds

    ABSTRACTThe City of Austin (City) operates a Flood Early Warning System (FEWS) to reduce public exposure to flash flood hazards. The system is operated and maintained by the Watershed Protection and Development Review Department, Watershed Engineering Division. Advanced information and warning of urban storm water flooding is achieved by the FEWS. A critical component of the system is rainfall ...

  • 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 ...

  • Get more out of Water Resources Engineering Models

    The effort required to develop water resources engineering models can be significant. But once developed, in many instances the models are only evaluated for a limited, or a single set of conditions. The results and predictions obtained from these evaluations are the ones used in design, presented in reports and conveyed to decision makers and the public. This approach might serve ...

  • Balancing Wetland Regulation with Stormwater Management on a Watershed-Wide Basis: A Case Study.

    Maryland reconciles rapid growth, water-quality goals, and habitat protection. In response to increasing regulatory authority over its water resources, the Maryland Department of the Environment (MDE) has combined various programs and processes into a 'one-stop shop' where various issues can be addressed in a uniform and consistent manner. As part of this process, onsite conditions are assessed, ...

  • Bioretention swales: a nonstructural bmp approach to achieve new standards

    ABSTRACT Bioretention swales are unique stormwater management facilities that possess the multifunctionality of conveying, treating, detaining, and infiltrating runoff. The bioretention system consists of an organic soil media layer that supports a robust ecosystem, including native vegetation, microorganisms, and macroinvertebrates. During the more frequent smaller storm events, which make ...

  • Sub-surface flow wetlands to treat glycol-contaminated stormwater from aircraft de-icing operations, Batea

    Airports use glycol-based aircraft de-icing fluids (ADFs) for removing ice and snow from aircraft surfaces during winter and under frost conditions. Some relatively concentrated, spent ADF (Concentrate) may be collected from beneath aircraft for recycle or disposal at a local wastewater treatment plant (WWTP), but a significant part of the ADF at everyairport will end up in sewers and ditches, be ...

  • Monitoring performance of a novel approach to channel design for environmentally- sensitive stormwater management: Lower Silver Creek, California

    Compound channel designs are increasingly being applied in urban watersheds to achieve both stormwater conveyance and ecosystem protection and restoration goals. A compound channel project was constructed on Lower Silver Creek in 2003, and a detailed monitoring program has been implemented to assess project performance and to improve future similar channel designs. Initial monitoring results ...

  • Flood protection in Miami Dade county - Case Study

    Introduction: Miami-Dade County has experienced remarkable growth over the past thirty years, with a population that has grown to 2.3 million. Consequently, difficulties exist in maintaining a stormwater management system that meets the increased needs of the community. Unusually large precipitation events in 1999 and 2000 caused flooding in some Miami neighborhoods that were built in ...
