Wastewater Plant Taking Proactive Measures To Protect Natural Resources

The Prince William County Service Authority carefully considers its impact to the environment when conducting wastewater treatment.

  • Submersible Pumps Eliminate Flood Damage Concerns At LaGuardia Airport
    Submersible Pumps Eliminate Flood Damage Concerns At LaGuardia Airport

    During Hurricane Sandy, La Guardia Airport’s five stormwater pump stations lost power, resulting in flooding of an estimated 100 million gallons of water.  The Port Authority of New York & New Jersey quickly moved up its planned renovations and installed nine axial flow pumps capable of moving large volumes of water at low heads. The propeller-type pumps have motors that are invulnerable to submersion during high-water incidents, improving the airport’s stormwater control, flexibility, and operational efficiency.

  • Flood Improvement And LID Modeling Using <B>XP‐SWMM</b>
    Flood Improvement And LID Modeling Using XP‐SWMM

    Over the years, a number of severe storms have impacted the Harris Gully watershed, including Tropical Storm Allison, which resulted in $5 billion in damages in 2001. Inundation was especially severe at the downstream portions of Harris Gully, where Rice University and the Texas Medical Center are located. A1D/2D hydraulic model (XPSWMM) was instrumental in simulating and evaluating the effects of a proposed drainage alternative.

  • Asset Inspections Are Optimal Tool For Maintenance And Capital Improvement

    Infrastructure asset inspection process is a tool that identifies deficiencies, creates backlog, establishes proactive maintenance, and monitors life cycles; as well as assists agencies in identifying projects for their Capital Improvement Program (CIP). These inspections can provide both a short-term benefit through work identification for repair and maintenance efforts and a long-term benefit of project identification of new capital improvements and enhancement.

  • Underground Treatment Of Airport Deicing Fluid
    Underground Treatment Of Airport Deicing Fluid While keeping air flight safe, airports and airlines are also obliged to clean up after themselves and protect nearby streams and water bodies. And due to increasing chemical usage and looming regulations, some airports will need to invest in significant infrastructure upgrades to capture and treat stormwater contaminated with deicing fluid.

  • White Paper: Passive Filter - Sustainable BMP For Permanent Stormwater Treatment Of Heavy Metals, Nutrients, Hydrocarbons And Sediment
    White Paper: Passive Filter - Sustainable BMP For Permanent Stormwater Treatment Of Heavy Metals, Nutrients, Hydrocarbons And Sediment Passive filtration provides a sustainable alternative to classical drainage concepts for source control of hydrocarbons, heavy metals, and nutrients that endanger our water bodies. In urban areas with high building density, traditional drainage concepts like wetlands are not available and the concept of decentralized treatment facilities that can be housed in catch basin structures are a viable option for treatment of pollutants. By Royal Environmental Systems, Inc.
  • Application Note: Employing Best Water Quality Monitoring Practices To Reduce Runoff During Construction Under proposed EPA stormwater runoff guidelines, construction site operators will be required to actively monitor or sample stormwater discharges daily. The enhanced effluent rules take effect in August 2011 for construction sites that disturb 20 or more acres and February 2014 for sites that disturb 10 or more acres, and they may stipulate a strict numerical limit of less than 280 NTU for average turbidity (sediment in water) on any day.
