Stormwater Management Case Studies and White Papers

  1. Using Technology And Best Business Practices To Make The Best Use Of Resources And Save Public Dollars
    2/13/2015

    Creating long-term efficiencies and sustainability is a huge focus of today’s government sector.  Every day the charge of Public Works’ leaders is to do more, with less. Further, technology, if used correctly, can be an effective tool for organizing work and cutting costs. 

  2. Ultrafiltration Stormwater Recovery System At Cincinnati Zoo Reaches Optimal Performance
    1/28/2015

    The Cincinnati Zoo uses an ultrafiltration system (UF) to treat stormwater. The reclaimed water is collected from 14 acres of the park, including parking lots, animal exhibit yards, rooftop drains, and walking path storm drains

  3. Decades-Old Storm Water Problem = Solved
    11/17/2014

    Located 16 miles southeast of Houston, Pasadena, TX, is the second-largest city in Harris County and home to 150,000 residents. Its proximity to the Gulf of Mexico means the city receives nearly 55 inches of rain each year, 17 inches above the state median. Combined with Pasadena’s relatively flat topography and poor drainage systems, heavy rainfall can cause flooding and block major highways.

  4. Wastewater Plant Taking Proactive Measures To Protect Natural Resources
    9/4/2014

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

  5. Constructing A Winding Box Culvert Channel In A Steep, Rocky Canyon
    4/3/2014

    Special precast box culverts were used for one of the most significant segments of the $25.8 million emergency water restoration project, designated by the NRCS, known as the Cache Water Restoration Project (CWRP). The CWRP project involved the reconstruction and improvement of approximately six miles of mostly open, unlined channels that make up the Logan and Northern, as well as the Hyde Park and Smithfield canals. The project incorporated new precast pipeline, box culverts, a section of pressurized pipe, metering systems, turn-outs, head gates, and improved maintenance access.

  6. Michigan Utility’s New Pumps Underscore Advancements In Wastewater Handling
    3/18/2014

    Ypsilanti’s pumps, originally put into service in 1982, became priority candidates for replacement after operating ten years beyond their expected 20 year service life. The Ypsilanti Community Utilities Authority (YCUA), included the project in the utility’s Master Plan.

  7. Submersible Pumps Eliminate Flood Damage Concerns At LaGuardia Airport
    1/23/2014

    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.

  8. Flood Improvement And LID Modeling Using XP‐SWMM
    9/30/2013

    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.

  9. Membrane Filtration Water Treatment Plant Meets Hotel Complex's Needs
    10/23/2012

    The Little America West Hotel complex located near the town of Granger, Wyoming, used an outdated surface water treatment plant that provided poor quality water during storm events.

  10. Stormwater Treatment and Reuse - Toronto, Ontario (Case Study)
    6/5/2012

    Sherbourne Common is an innovative waterfront park that provides the public with green recreational space along Lake Ontario in a former industrial area.
