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..

PFAS Funding Is Flowing — But Does The Water Sector Have Enough People To Deliver It?
For several years, the PFAS conversation has centered on treatment options, testing, and funding. Those factors still matter, but they are no longer the primary constraint. Most utilities already understand the treatment routes available to them; the real challenge now is moving from technical possibility to operational performance, and that depends entirely on people.  Continue Reading..

Sunscreen For Lakes And Dams: Could A Thin Floating Layer Of Nanomaterial Shield Water From Evaporation?
Water stored in dams and reservoirs for humans to use often evaporates, especially in hot regions like southern Africa. Rising temperatures speed evaporation up, leaving less water for people, farming and industry. Daniel Kwasi Kpeglo has just completed a PhD in physics. He explains his laboratory research into a new design – a thin nanomaterial floating cover that could be placed over lakes and dams like a blanket, reducing evaporation by...  Continue Reading..

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."

Can Wastewater Be Reused In Pharmaceutical Production?

In Denmark, industry's absolute water consumption was almost at the same level in 2022 as in 2012, according to an analysis from the Danish Academy of Technical Sciences (ATV).

John Crane Helps German Sugar Producer Save More Than 6.2 Million Litres Of Water During A Six-Month Production Season

John Crane, a global leader in flow-control technologies and an innovator in solutions for rotating equipment, and a business of Smiths Group plc, has helped a German sugar producer reduce the water required for mechanical seal cooling and lubrication by approximately 80%. Across a full six-month production season, the reduction is equivalent to saving more than 6.2 million litres of water. 

De Nora Awarded Contract Worth About Euro 30 Million For A Water Treatment Plant Serving A Semiconductor Facility In Southeast Asia
