Wastewater Features

  1. As Climate Change Amplifies Urban Flooding, Here's How Communities Can Become 'Sponge Cities' 5/9/2024
    Across the continental U.S., intense single-day precipitation events are growing more frequent, fueled by warming air that can hold increasing levels of moisture. Most recently, areas north of Houston received 12–20" of rain in several days in early May 2024, leading to swamped roads and evacuations. Events like these have sparked interest in so-called sponge cities — a comprehensive approach to urban flood mitigation that uses innovative landscape and drainage designs to reduce and slow down runoff, while allowing certain parts of the city to flood safely during extreme weather.
  2. 6 Steps To Improving Energy Efficiency In Water And Wastewater Operations 5/7/2024
    Water and wastewater utilities account for nearly 4% of the world's energy consumption. With emissions targets looming and pressures building around water tariffs that frequently fall short of covering costs, there's an urgent need to reduce energy usage. This means tackling inefficient processes, such as mechanical flow control and the use of oversized equipment.
  3. What Cities Everywhere Can Learn From The Houston Area's Severe Flooding As They Try To Adapt To Climate Change 5/5/2024

    Floods are complex events, and they are about more than just heavy rain. Each community has its own unique geography and climate that can exacerbate flooding. On top of those risks, extreme downpours are becoming more common as global temperatures rise.

  4. Reducing Wastewater Hauling Through An Advanced Membrane Treatment Technology 5/3/2024
    Hauling wastewater is one of the most expensive and least sustainable means of managing wastewater, significantly impacting the environment through carbon emissions, and drastically increasing operational costs. As industries strive to meet environmental and economic goals, finding sustainable wastewater treatment methods is needed — now more than ever.
  5. From Scarcity To Stewardship To Sustainability 5/2/2024
    Every drop of water counts, but when we talk about our collective conservation efforts for the greater good, it's natural to think about high-volume users. Those users are generally on the industrial side of things — agriculture, of course; the energy industry, with its intractable relationship to water; and also the food and beverage industry. Thankfully, there are leaders in these spaces who not only understand the need for sustainable water management — they pioneer it.
  6. The Zen Of Stormwater Management And Land Development 5/2/2024
    Plans for land development should include a plan for stormwater as well, incorporating both natural and engineered solutions.
  7. Protecting Our Planet Daily: Water And Wastewater Technologies At The Forefront Of Sustainability 4/23/2024
    Water Online spoke with Teresa Ortigosa, Global Sustainability Director at Veolia Water Technologies, to get her thoughts on the planet's biggest environmental threats, recommended practices to make us more sustainable, and some technology solutions to help enable the transition.
  8. Advancing Water Reuse In The U.S.: States Develop Potable Reuse Regulations 4/17/2024
    In several U.S. states, government agencies and utilities are exploring how to treat wastewater properly so it can be used for drinking water — what we know as potable water reuse. While potable reuse is not a new concept, it's being pursued more aggressively with renewed support and new ideas as we see limits with existing water sources.
  9. Advantages Of Membrane Cell Hypochlorite Generators Over Open Cell System Technology 4/15/2024
    In an era where waterborne pathogens are evolving and regulatory standards are tightening, the role of supplementary disinfection in water treatment for municipal operators and industrial facility engineers has never been more crucial.
  10. Water Is Beer 3/25/2024
    My water career started with beer. No, not the amount I drank on my way to my chemical engineering degree at Manhattan College. I mean the 10,000+ hours I spent optimizing filtration systems in breweries throughout the world.
