Wastewater Case Studies and Whitepapers

  1. Green Stormwater Infrastructure Is Having Its Day 8/13/2020

    Not long ago, systems engineered to manage and mitigate stormwater runoff were predominately of the “gray” variety. Today, however, more and more municipalities are embracing green stormwater infrastructure (GSI).  

  2. Retrofitting Water Systems With The Best Meters For The Job 4/14/2020

    Although not every water, wastewater, or industrial design engineer or operations manager is familiar with the advantages of the V-Cone differential-pressure (DP) meter design, they are certainly familiar with the problems it can solve. Here is a step-by-step description of how V-Cone meters with + 0.5 percent accuracy offer better alternatives in applications currently being failed by other metering technologies.

  3. How To Bridge The Wastewater Infrastructure Gap 8/28/2025

    Across the country, wastewater systems are reaching the end of their intended lifespans. Most treatment plants were designed to operate for 40–50 years. Now, many are now overdue for major upgrades or full replacements. This issue is compounded by decades of declining investment.

  4. Real-Time Decision Support System Exceeds Expectations -- Buffalo Cuts CSOs By 450 Million Gallons, Reducing Consent Agreement By $145 Million 8/4/2020

    Recognizing the generally inadequate stormwater capabilities of their existing combined sewer system, the Buffalo Sewer Authority (BSA) began to prepare a comprehensive watershed improvement plan with grey, green and smart sewer solutions.

  5. Refinery Treats Groundwater Contamination While Saving Precious Facility Space 3/20/2020

    A large, Midwestern oil refinery installed two identical, 110’ diameter S&L Model R OXIGEST® treatment systems to solve a groundwater treatment problem on-site. Each plant incorporates aeration, clarification, and effluent holding, treating peak flows of 7.2 MGD combined; 4.3 MGD in each plant.

  6. Step Screen Replaced By Headworks 9/1/2014

    In May 2008, Portland Water District installed 3 step screens in each of their 3 channels and in only 7 years of use, were facing maintenance & performance issues with the step screens. These screens were also affecting downstream processes.

  7. Advances In UV Disinfection For Wastewater Tertiary Treatment In Open Channels 10/2/2025

    Meeting modern water reuse goals requires moving past legacy disinfection. Advances in UV technology now provide chemical-free, reliable pathogen inactivation for even high-flow, open-channel tertiary treatment.

  8. Grand Rapids, MI Saves $1 Billion Using "Smart Sewer" Technology To Solve Infiltration And Inflow Problem 1/31/2020

    In the early 1990s, Grand Rapids took the initiative to invest in transforming its collection system from a combined sewer system to separate storm and sanitary sewers.

  9. Operational Resilience Through Temporary Water Reuse Solutions 8/11/2025

    Temporary water reuse systems help industrial plants avoid costly downtime by maintaining treatment capabilities during maintenance, failure, or testing—offering fast deployment, flexibility, and permanent-quality results.

  10. After You Own It: Cutting OpEx And Scaling Legacy Plants With Modern MBR Technology 8/7/2025

    For private utility owners and operators, legacy infrastructure isn’t a sunk cost. It’s an opportunity. And with the right retrofit strategy, that aging wastewater treatment facility can become a stable, revenue-generating asset.
