    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.

    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 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
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.

Peracetic Acid Offers Single Step Treatment Of Wet Weather Flows

Peracetic Acid Offers Single Step Treatment Of Wet Weather Flows

Many utilities are looking at peracetic acid (PAA) as a safe means to quickly treat sewer overflows when treating storm water. Because PAA, which is created by mixing peroxide with acetic acid, contains different properties than traditional chlorine compounds, it doesn’t come with chlorine-related disinfection byproducts.
