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..

Many Cities Buried Urban Streams. Here's How To Bring Them Back
As many cities developed, streams that once flowed on the surface were buried underground to make way for growing infrastructure. However, as heavier rainfall, extreme weather and aging infrastructure place growing pressure on cities, these buried streams could become part of the solution. Restoring streams to the surface — a practice known as stream daylighting — can help manage stormwater, restore habitats, and create greener, more...  Continue Reading..

Inside Zero Liquid Discharge Systems: The Technology Driving Industrial Water Reuse
Zero liquid discharge (ZLD) is evolving from a wastewater-compliance strategy into a high-recovery separation platform built around reverse osmosis (RO), high-pressure membranes, thermal concentration, membrane distillation (MD), crystallization, sensors, and process controls. Its objective is measurable: maximize water recovery while converting dissolved salts into solids rather than producing a final liquid reject.  Continue Reading..

From Warning To Reality: Lessons From The Latest OT Attacks On Water Utilities
On July 10, I published an article warning that water and wastewater utilities had become prime targets for state-sponsored cyber actors, describing how attackers exploit internet-exposed PLCs, how the IT/OT divide leaves organizations vulnerable, and why the sector needed to act before an incident forced their hand. Today, that scenario is no longer hypothetical.  Continue Reading..

Advanced Water Treatment Strategies Help Data Centers Manage Cooling Water At Industrial Scale
Data centers are evolving into industrial-scale thermal-management facilities as artificial intelligence (AI), high-performance computing (HPC), cloud platforms, and accelerated computing increase rack power density. Modern AI racks can exceed 50–120 kW per rack, creating substantially higher heat-rejection requirements than conventional enterprise infrastructure. ASHRAE's (American Society of Heating, Refrigerating and...  Continue Reading..

From Diagnosis To Decision: Four Pillars Of Actionable Pipeline Intelligence
Aging underground networks require actionable intelligence to prioritize maintenance. Combining flexible screening, accurate spatial positioning, and rapid data access helps utilities pinpoint critical defects, reduce operational disruptions, and optimize long-term capital improvement planning.  Continue Reading..

Putting Pipelines On The Map: How Location Data Strengthens Modern Asset Management Programs
Incomplete pipeline records jeopardize modern utility management. Precise spatial mapping and elevation data protect underground infrastructure, reduce utility strikes during excavation, and enhance digital models to enable targeted, cost-effective infrastructure maintenance.  Continue Reading..

How To Manage Warm-Season Biological Upsets In Wastewater Lagoons
The rate of biological activity in a treatment lagoon is largely a function of water temperature. Once the water rises above roughly 59 °F (15 °C), metabolic rates increase across the entire microbial and invertebrate community.  Continue Reading..

Untreated Sewage And The Search For Affordable Biological Solutions

Researchers have isolated naturally occurring light-driven bacteria from local pond water and shown that, within just one week, these microorganisms can substantially reduce the levels of organic pollutants in raw sewage — pointing toward a low-cost, environmentally sound approach to wastewater treatment

RedVeil Extends AI-Powered Penetration Testing Relief Package To Municipal Infrastructure Organizations

Following recent cyberattacks targeting municipal water systems across the United States, RedVeil, the leading AI-driven penetration testing platform, today announced an initiative to help municipalities and critical infrastructure providers fortify their defenses.

Heavy Water Helps Weather Forecasts

Weather forecasts rely on many and various kinds of data, including temperature, humidity and wind data. For the first time, researchers including those at the University of Tokyo demonstrate that a long-theorized improvement to weather models by adding data on water isotopes in the atmosphere does in fact work.

Gradiant Secures Major Water Contract For Hyperscaler AI Data Center Campus in West Texas

As AI data center capacity races to keep pace with compute demand, water has become one of the sharpest constraints on where, and how fast, new facilities can be built. Nowhere is that clearer than West Texas, where one of the nation’s largest AI infrastructure developments is taking shape in a region with limited water resources.

District Maintains Water Service During Critical Infrastructure Upgrade With AVT EZ Valve Technology

The Star Sewer and Water District in Idaho has successfully completed a critical water infrastructure upgrade using AVT's EZ Valve insertion valve technology, allowing crews to install a new water line connection without interrupting service to existing customers.

$7.9 Million NSF Investment Brings Vermont Researchers Together To Address 'Forever Chemical' Contamination

The U.S. National Science Foundation has awarded $7.9 million to establish the PFAS Environmental Research Network (PERN), a four-year initiative bringing together Vermont researchers, educators, students, and state partners to better understand and address environmental chemical contamination.
