What Utilities Don't Know About GAC Reuse For PFAS
For utilities building PFAS treatment systems, thermal reactivation of spent granular activated carbon (GAC) may sound like the obvious answer. However, service provider availability and location, specific media acceptance criteria including quantity thresholds, restrictions on GAC type and condition, and regulatory uncertainty can all determine whether reuse is a viable option.   Continue Reading..

Beyond Water-Stress Scores: Assessing Infrastructure Resilience At The Asset Level
Water-stress screening can identify where an infrastructure asset deserves closer attention. Assessing resilience requires further steps: understanding the asset’s water profile, the reliability and security of its supply, the pressure it places on local resources, and whether adaptation can keep it operational and economically viable over time.  Continue Reading..

Colorado River Conservation Depends On The Delivery System
The Department of the Interior issued the 2027-2028 Operating Guidelines, calling for Lower Basin deliveries to drop by 1.25 million acre-feet annually in 2027 and 2028, with a minimum of 700,000 acre-feet of additional voluntary conservation over those two years. While temporary reductions are a start, water districts and water professionals should also consider delivery upgrades and on-farm improvements in agricultural areas that prepare...  Continue Reading..

Why Water Utilities Need Better Asset History, Not Just More Maintenance Data
For water and wastewater utilities, better asset history is not about collecting more data for its own sake. It’s about making existing inspection and maintenance information useful enough to support reliability, maintenance prioritization, capital planning, and long-term service delivery.  Continue Reading..

125 Years Of Engineering That Changed How The World Moves Water

As aging infrastructure, rising costs and more demanding operating conditions put greater pressure on critical systems, Xylem marks 125 years of Flygt engineering heritage and the breakthroughs that have helped make pumping more reliable, efficient and intelligent.

Study Predicts Large Disparities In Access To Food, Water, And Energy In 2050

In some regions of the world, the poorest people may spend about 50 percent of their income on food, while the richest spend about 5 percent.

Desalination And Reuse Event Explores Water Resilient Future

As global demand for freshwater continues to rise, the need for innovative solutions has never been more critical. In the UK, England alone could face a public water supply shortfall of up to 5 billion litres per day by 2055.

EPA Launches Cutting-Edge Scientific Study To Strengthen Nation's Understanding Of Potential Pollutants In Drinking Water

Today, U.S. Environmental Protection Agency (EPA) announced a new scientific study using cutting-edge methods to improve the agency’s understanding of what pollutants may be present in drinking water. This groundbreaking new research by EPA scientists goes beyond traditional testing methods to screen for a broad array of pollutants, including pharmaceuticals, PFAS, and more than 1,000 potential contaminants. This action advances EPA’s commitment to help Make America Healthy Again while following gold standard science.

America's Wastewater Plants Could Be A Much Bigger Source Of Renewable Power

Wastewater treatment plants in many American communities are doing more than treating sewage – they’re also producing renewable energy. According to new data released today from the American Biogas Council, 1,200 wastewater treatment plants across the United States currently capture and use biogas produced from wastewater sludge. That means wastewater treatment plants account for nearly half of the approximately 2,600 biogas facilities of all types operating in the United States today.

Professional Biogas Project Contractor For Industrial Wastewater Treatment Using UASB Process & GFS Tanks

The global policy framework for industrial wastewater treatment is undergoing a fundamental transformation, escalating from mere "compliance discharge" to mandatory "resource recovery" and "zero liquid discharge."
