  • Soaking In Another Victory
    Soaking In Another Victory

    It’s a four-peat.

    For the fourth consecutive year, the University of Maryland, College Park has won high honors in EPA’s Campus RainWorks Challenge, a national collegiate competition to design the best ideas for capturing stormwater on campus before it can harm waterways.

  • Top 10 Considerations For Designing And Installing Your Stormwater System
    Top 10 Considerations For Designing And Installing Your Stormwater System

    Designing an underground stormwater storage system is a unique step in the overall construction process for each site. The size of the inlets and the conveyance pipes are determined by flow rate, elevation, and slope. This information is entered and calculated by stormwater management software to determine the drainage calculation. But many of the measures build upon one another or vary based on different criteria, so it can be a pretty complex process. That’s why we’re going to take a look at the top 10 factors that go into designing and installing one of these systems.

  • Point Level vs. Continuous Level Measuring Technologies
    Point Level vs. Continuous Level Measuring Technologies

    While point level measuring approaches are regarded as simple and user-friendly, they lack the capabilities of more sophisticated continuous measuring instruments.

    How Sludge-To-Energy Technology Is Boosting Water Resilience And Slashing Emissions For Cities

    Growing cities are generating higher volumes of wastewater and putting a strain on clean water supplies, calling for solutions that extract value from “waste” and ensure the sustainability of resources — with the added bonus, or imperative, of protecting the environment.

  • Aqua Rhino In-Channel Escalating Screen
    Aqua Rhino In-Channel Escalating Screen

    This video provides a simple overview of the screen’s creation, function, features and benefits. From the beginning, Parkson engineers took it a step further by working with a leading design firm to rethink the industry standard step style screen from the ground up. They reviewed current offerings on the market and improved upon the common weak points. The result is the most durable escalating screen out there – the Aqua Rhino.

  • Savings Helps MABRs Gain Traction In Municipalities
    Savings Helps MABRs Gain Traction In Municipalities

    An MABR is essentially a biological wastewater treatment process that utilizes seemingly passive aeration through oxygen-permeable membranes. Oxygen transfer through the MABR membranes is diffusion based: driven by concentration differences such that oxygen passes from air at atmospheric pressure into water at a higher hydrostatic pressure. This oxygen transfer mechanism, wherein air is supplied to the process at very low pressure, is the reason MABRs have significantly lower energy consumption compared to other wastewater treatment processes, such as conventional activated sludge (CAS), that utilize diffusers. This energy savings is one of the key reasons MABRs are gaining traction in the municipal wastewater industry.

    DC Water’s Unconventional Approach To Utility Management

    Over the past 10 years, DC Water has become the harbinger of the modern water utility. It’s often unconventional approach to tackling age-old problems usually elicits one of two responses from other utility professionals. The first response is one of resignation — if only I had the budget that size permits, I’d be able to do similar things. And the second is one of awe — there’s no way I have the amount of gumption to convince regulators or customers that I have a better way.

  • Pulling Together: Public-Private Partnerships Poised To Push California Water Efficiency
    Pulling Together: Public-Private Partnerships Poised To Push California Water Efficiency

    California is home to some of the world’s most creative minds, top universities, productive farmland, groundbreaking industries — and one of the most epic droughts. The state has endured five years of drained reservoirs and groundwater reserves tapped so aggressively that the land subsidence caused by pumping has been literally seen from space. This indicates in no uncertain terms that it’s time to get all hands on deck. Private companies, universities, irrigation and drainage districts, municipalities — it’s time to pull together into public-private partnerships to address water challenges that face California and so many other regions of the world.

  • Biosimilar Producer Relies On Flexible Development Platform To Speed Time To Market
    Biosimilar Producer Relies On Flexible Development Platform To Speed Time To Market

    To help drive sales, producers of biosimilar medicines seek to gain as much pricing advantage as possible over their products’ reference biological medicines while maintaining as much profit margin as they can. That’s why they are always looking to minimize production costs, especially in raw materials and labor, their largest cost components. While the costs of the former depend on market prices and a buyer’s negotiating skills, the latter can be best reduced through automation and continuous processing.

  • Affordable Sewer For Small Communities
    Affordable Sewer For Small Communities

    Affordability and maintainability are two of the greatest challenges small municipalities face when constructing and managing sewer infrastructure. With these challenges in mind, it’s important for small cities to choose wisely when investing in a wastewater system that needs to last for 30-60 years.

    What Happens To The Chesapeake Bay Now?

    One of the great turnaround stories in the history of our nation’s water bodies is that of the Chesapeake Bay.

    Now that you have returned to the role of private citizen — though, admittedly you are a private citizen with millions of eyes focused on you — I want to encourage you to continue your great work promoting the health of our nation’s children. Your emphasis on exercise and nutrition, jobs and support for veterans, and education have touched millions of Americans of all ages and all backgrounds. Now it’s time to bring in the most common denominator and the first step toward good health — access to clean water.

    Municipal Water District Goes All-In With Ignition

    For a 24-hour-a-day, seven-day-a-week water and waste water management operation, having a supervisory control and data acquisition (SCADA) system is a must. A SCADA system should make workers’ jobs easier, but if it’s not working properly, or it’s unable to keep up as the enterprise expands and upgrades its processes, it becomes a hassle to deal with.

    Is Cryptocurrency Going Down the Drain?

    Talk about making waves. Cryptocurrency — digital “tokens” or “coins” rooted in computer code and valued for the very fact that they are disconnected from governments and banks — have experienced spectacular rises and falls in recent months. The crypto-economy is already worth hundreds of billions of dollars (REAL dollars!), and it’s anyone’s guess how fast it will grow after that.
