    Navigating The Waters of the United States Rule

    On December 11th, the U.S. Environmental Protection Agency (EPA) and the Department of the Army (Army) proposed a new definition of “Waters of the United States” to replace the 2015 definition adopted under the Obama administration. That definition has been subject to a variety of litigation over the past three years, causing its application to be sporadic at best.

  • Enhancing HVAC Performance: Siemens Clamp-On Flow Meters Chosen For NYC Building Complex
    Enhancing HVAC Performance: Siemens Clamp-On Flow Meters Chosen For NYC Building Complex

    A commercial real estate corporation that owns, develops and operates premier properties in major North American cities was one of the earliest companies to recognize the benefit of individually metering tenants for their utility usage. When designing a prestigious building complex in New York City, the company sought a flow meter that would facilitate this task. After careful consideration of several options, the choice became clear: clamp-on ultrasonic flow technology from Siemens.

  • Saving Energy And Enhancing Environmental Sustainability At A Top University In Asia
    Saving Energy And Enhancing Environmental Sustainability At A Top University In Asia

    At one of the most prestigious universities in Asia, the main campus comprises a large number of buildings clustered within an area less than 2 km2 (1.2 mi2). Because the university was built more than a century ago, many facilities on the campus were never fitted with the proper instrumentation for energy measurement, making it difficult or impossible to monitor the performance of most HVAC systems, including the cooling system.

  • How Do You Know If Your Ozone Contacting System Is Well Mixed?
    How Do You Know If Your Ozone Contacting System Is Well Mixed?

    Mixing is something that is often taken for granted when designing systems for water and wastewater treatment. Perhaps “taken for granted” is too harsh a term. Let’s instead say that while designing a treatment unit operation or process, mixing as a phenomenon is automatically assumed to occur — an assumption that forms the basis for process controls, performance guarantees and measurement methods and locations.
