Bridging The Gap: Equitable Investment In City Greenspace
Every year, an estimated 10 trillion gallons of untreated stormwater runoff containing raw sewage, fertilizer, oil, pesticides, bacteria and other pollutants enter U.S. streams, rivers and oceans from city sewer systems, polluting the environment and drinking water supplies. In many urban and suburban areas, this runoff also causes significant flooding.
-
Basics Of Mixing By Submersible Mixers
Understanding the basics of mixing not only helps wastewater treatment plants (WWTPs) to meet treatment goals but can also reduce operating costs.
-
Improving Total Nitrogen Removal
To protect the sensitive waters of the Neuse River Basin, the State of North Carolina formally adopted a nutrient management strategy in 1997 which established Total Maximum Daily Loads for all point source contributors of Total Nitrogen (TN) to the Neuse River. By upgrading its oxidation ditches, this Eastern NC plant saw a reduction of 76% TN compared to its average discharge from the past 6 years.

Microbial Control In Cheese Making
Microbial contamination of food and beverage products is a potentially catastrophic occurrence resulting in foodborne illness or food spoilage. The same nutritive properties that render cheese and dairy products such a valuable food also provide an ideal growth medium for microbes if contamination occurs.
LATEST INSIGHTS ON WASTEWATER
-
As water systems become more circular and complex, understanding and managing the subsurface — the hidden half of the water cycle — is becoming a critical enabler of resilience. This article explores the key trends shaping this new reality, from tackling “forever chemicals” to the water strategies redefining heavy industry.
-
The White House has finalized plans to roll back rules under the National Environmental Policy Act (NEPA), narrowing its focus and limiting what the current administration claims are needless delays for federal approval of water, energy, and other infrastructure plans. For water and wastewater utilities, the changes could speed up permitting for critical projects, although experts warn the tradeoffs could do more harm than good.
-
Traditional sewer systems, while effective, often require significant capital investment, invasive implementation measures, and complex maintenance. As a result, innovative decentralized wastewater solutions are necessary to address the needs of communities or commercial areas in need of wastewater service. One such solution is the liquid-only sewer (LOS) system.
-
While many scientific and technical reports show that floods are becoming larger and more common, reports underestimate how their frequency is changing. Flood sizes get the spotlight, but governments and experts need to also consider their frequency to address implications overlooked by traditional management methods.
-
In areas with storm drains, the water can quickly overwhelm the drains, causing flooding hazards. For this reason, many towns have ordinances dictating how much ground can be covered with impermeable substrates.
