Sewers & Sewer Line Maintenance White Papers & Case Studies

  1. A Handy Tool For Wet Well Maintenance: Cutting Through The FOG
    1/4/2016

    Blame our fast food diets or restaurants’ negligence for what’s going down the drain. Whatever the cause, fats, oil, and grease (FOG) accumulation has become a pervasive problem for wastewater treat­ment plant collection systems.

  2. Analytical Software Predicts Sewer System Blockages
    10/10/2018

    Using historical data and Seeq analytical software, Nukon calculates when sewer blockages will occur up to 13 hours before occurrence, preventing spills.

  3. Repair Of Major Damage To High Density Polyethylene Wastewater Pipeline
    8/13/2018

    Leprino Foods, the world's largest mozzarella cheese producer, operates two plants that share one wastewater pipeline – a 16” SDR11 High Density Polyethylene Pipeline (operating at approximately 160 PSI). During dirt work an “auger” hit the wastewater pipeline and drilled an 8” diameter hole in the line. Leprino needed immediate access to a repair fitting for this line.

  4. Last-Minute Design Change Benefits Akron Project
    8/7/2018

    The Great Lakes region was blessed with abundant freshwater for its rivers and lakes. Water as a resource and method of transportation were an important factor in Akron, OH, blossoming as one of America’s early manufacturing hubs during the late 1800s and early 1900s.

  5. Historic Town Remedies FOG Problem
    2/21/2018

    Among the pump stations managed by Branford, CT, is a long-term problematic station located at Burban Street. There were two primary problems at this station: 1) clogging from modern day trash and raggy, stringy materials, and 2) fats, oils, and grease (FOG) from a nearby nursing home and restaurants, which accumulate and float on the water surface, resulting in a horrendous mess.

  6. Preserving The Bay Area
    11/7/2017

    With any aging system, inspection, cleaning, rehabilitation, and repair is essential to maintaining the systems integrity.  The City of Oakland, CA, the largest city in the East Bay region, certainly has its share of utilities to maintain.  The City of Oakland’s sanitary sewer system encompasses over 930 miles of sanitary sewer pipes and includes 31,000 structures and seven pump/lift stations.

  7. AMERICAN Provides ‘Major League’ Solutions For Atlanta Braves’ New Stadium
    7/27/2017

    The toughness of AMERICAN ductile iron pipe was put to the test on a recent project that changed a significant portion of the landscape in Cobb County, Georgia: SunTrust Park, the new home of Major League Baseball’s Atlanta Braves.

  8. Enhancing Water System Reliability And Capacity For Boston Residents
    4/28/2017

    Enhancing process reliability and increasing capacity are common issues facing water municipalities. On the one hand, community demographics are constantly evolving and water municipalities need to accommodate the impact to capacity requirements. At the same time, older systems that support pumping operations are not getting any younger and as control systems age, for example, it can become more time consuming to maintain equipment and more difficult to find replacement parts after systems have been in place for many years.

  9. Variable Frequency Drive In Wastewater Treatment Stations
    1/25/2017

    Just 20 years ago, many professionals did not consider using variable frequency drives (VFDs) in wastewater applications. Frequency converters were relatively expensive, and experience using them with the special conditions and requirements in wastewater was limited.

  10. Collection System Aeration And The Microbial Benefits
    4/14/2016

    In late 2015 Reliant Water Technologies introduced the Wet Well Wizard, an aeration tool for the wet wells in collection systems.  During 14 months of field testing the patent pending Wizard System, the primary objectives were to eliminate FOG (fat, oil and grease) caps and to reduce H2S, eliminating it if possible.
