Stormwater Wetland Reduces Sewer Overflow By 84 Percent
Stormwater Wetland Reduces Sewer Overflow By 84 Percent

Through hydraulic computer modeling, MWH Global helped alleviate stormwater flooding in Cambridge, M.A., by creating the Alewife Reservation Stormwater Wetland to enhance water quality and provide recreational benefits to the community.

  • Addressing Chronic Flooding In Texas
    Addressing Chronic Flooding In Texas

    The city of El Paso, TX, lies on the tip of the Chihuahuan desert, and it is not uncommon for a year’s worth of rain to occur in a matter of days during the summer.

  • Hydro-Guard® Improves Water Quality And Saves Man-Hours For Central Texas Vacation Community
    Hydro-Guard® Improves Water Quality And Saves Man-Hours For Central Texas Vacation Community

    The user population of a Central Texas resort system does not reach its peak until summer and the resultant levels of peak and low usage vary widely. This fluctuation impacts levels of disinfectant residual and, consequently, water quality — especially at the end of the line. Manual flushing of the utility's hydrants to maintain water quality has resulted in excessive time and labor as workers must access the outlying areas.

    Using Technology And Best Business Practices To Make The Best Use Of Resources And Save Public Dollars

    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. 

  • Ultrafiltration Stormwater Recovery System At Cincinnati Zoo Reaches Optimal Performance
    Ultrafiltration Stormwater Recovery System At Cincinnati Zoo Reaches Optimal Performance

    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

  • Decades-Old Storm Water Problem = Solved
    Decades-Old Storm Water Problem = Solved

    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.

  • Constructing A Winding Box Culvert Channel In A Steep, Rocky Canyon
    Constructing A Winding Box Culvert Channel In A Steep, Rocky Canyon

    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.

  • Michigan Utility’s New Pumps Underscore Advancements In Wastewater Handling
    Michigan Utility’s New Pumps Underscore Advancements In Wastewater Handling

    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.

  • 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.
