  • Pittsburgh’s got grit, but Army Corps signs partnership agreement to help filter out the muck

    To combat the grit problem in the sewer systems, the U.S. Army Corps of Engineers Pittsburgh District signed a partnership agreement with the Allegheny County Sanitary Authority (ALCOSAN), which will construct a grit chamber along Spring Garden Run, a neighborhood located in the northern area of Pittsburgh.

  • Pittsburgh District to partner with Allegheny County Sanitary Authority for $4.3 million project

    The U.S. Army Corps of Engineers Pittsburgh District will sign a partnership agreement with the Allegheny County Sanitary Authority (ALCOSAN) to construct a grit chamber along Spring Garden as part of a $4.3 million environmental infrastructure project in Pittsburgh, Jan. 11.

  • Water Resources Development Act of 2022 authorizes Pittsburgh District additional projects for civil works and studies to benefit water infrastructure

    The U.S. Army Corps of Engineers Pittsburgh District received new and increased authorizations to support water infrastructure and civil works projects within its 26,000 square-mile region with the approval of the Water Resources Development Act (WRDA) of 2022, signed into law by President Joe Biden.

  • ERDC’s Martinez-Guerra applies military installation expertise to Jackson water crisis

    VICKSBURG, Miss., - By now, many have heard of the recent water crisis affecting the city of Jackson, Mississippi. Many may not realize, however, that a research environmental engineer from the U.S. Army Engineer Research and Development Center (ERDC) Environmental Laboratory, Dr. Edith Martinez-Guerra, applied her expertise with military installations to help assess the troubled system.

  • Corps to Host Frederick Heights Waterline Project Dedication Ceremony

    The U.S. Army Corps of Engineers Pittsburgh District is hosting a project dedication ceremony marking the completion of the $1.3 million Buckeye Water District’s Frederick Heights Waterline Project in Columbiana County, Ohio. The project expands the water distribution system to service Frederick Heights neighborhood residents in St. Clair Township.

  • Corps to Host Project Dedication Ceremony in Henry Clay Township

    FAYETTE COUNTY, Pa. – The U.S. Army Corps of Engineers Pittsburgh District is hosting a project dedication ceremony marking the completion of the National Pike Water Authority (NPWA) storage tank project in Henry Clay Township in Fayette County, Pennsylvania. The project increases the potable water supply to residents in four Fayette County municipalities.

  • Gavins Point Winter Releases Will be at Minimum Rates

    Drought conditions in the Missouri River Basin above Sioux City, Iowa, continued throughout the month of August. Per the Master Manual and the September 1 System storage check, winter releases from Gavins Point Dam will be 12,000 cubic feet per second (cfs), as part of the overall water conservation measures.

  • Heat wave fuels needless drownings, boating deaths in Oregon

    Drownings and boating-related deaths needlessly continue claiming lives in Oregon, recently fueled by a heat wave. The Oregon State Marine Board (OSMB) reported 19 boating-related fatalities in 2021 and the Oregon Health Authority recorded 57 drownings in natural waters in 2020, which is 160% increase from 2019 (35 drownings). Life jackets may have prevented many of these deaths.

  • Coordinated action critical to preventing flooding in Portland, Vancouver

    PORTLAND, Ore. – Coordinated operations of storage reservoirs across the Columbia Basin reduced water levels by nine feet near Portland and Vancouver in mid-June preventing additional flood damage attributable to a powerful atmospheric river that impacted most of the four-state region, and beyond.

  • Effects of Impure Water Sources on Early-Age Properties of Calcium Sulfoaluminate Cements for Rapid Airfield Damage Recovery

    Abstract: In austere environments with limited access to clean water, it is advantageous to use nonpotable water for construction (i.e., mixing water for concrete.) In rapid-response situations such as rapid airfield damage recovery (RADR), the use of calcium sulfoaluminate (CSA) cements is beneficial for expedient pavement repairs because of their rapid strength gain characteristics. However, the hydration products formed by CSA cements are substantially different from those formed by ordinary portland cement and might react differently to impurities that water sources may contain. A laboratory study component investigated the application of various salts and impure sources of mixing water with commercially available CSA cement-based products. A field component studied the application of naturally occurring impure water sources for RADR. Recommendations are made for implementation of impure mixing water for RADR using commercially available flowable fill and concrete products made with CSA cement.
