Brackish Water Desalination: A Strategic Imperative For Sustainable Water Stewardship In American Landscape
As droughts intensify, groundwater depletes, and climate extremes worsen, many water-stressed regions are increasingly turning to brackish groundwater desalination, for both potable use and industrial applications where water quality demands are less stringent. Hence, brackish water reserves are emerging fast as a strategic priority, ensuring a supplement for long-term national water security.  Continue Reading..

Why Smart Valves Are About To Redefine Water Infrastructure
For years, water metering followed a predictable path: manual reads, AMR, AMI, more visibility, more data. But utilities are now entering a different operational reality. Visibility alone no longer protects infrastructure.  Continue Reading..

The Resilient Utility: Why AI Is The New Social Safety Net For Water
For vulnerable communities, the cost of infrastructure fragility is not just financial; it is existential. By shifting our focus from "smart water" to "resilient water," we can use AI to build a social safety net that protects both our infrastructure and the communities that depend on it.  Continue Reading..

From Compliance To Resilience: Practical Lessons In OT Recovery For Water Utilities
Water and wastewater utilities have become attractive targets for cybercriminals and state-sponsored actors. CISA has repeatedly warned that drinking water and wastewater systems are vulnerable because they often lack the resources and technical capacity to adopt rigorous cybersecurity practices. The question is no longer whether your utility will face a cyber incident, but when — and whether you will be ready.  Continue Reading..

Transparent Exopolymer Particles (TEP): The Invisible Driver Of Biofouling In Water Systems
A growing body of scientific evidence points to transparent exopolymer particles (TEP) as one of the most important, but frequently overlooked, drivers of biofouling in water systems. Understanding TEP may provide a new perspective on why biofilms develop so rapidly, why some treatment systems foul despite acceptable microbial counts, and why conventional control strategies often struggle to deliver lasting results.  Continue Reading..

EPA Hosts States, Water Systems, And Small Communities To Collaboratively Accelerate Investments In Water Infrastructure

Yesterday, the U.S. Environmental Protection Agency (EPA) convened a roundtable on water infrastructure programs, including the State Revolving Funds, to identify and address challenges in program implementation that can result in delays in vital drinking water, wastewater, and stormwater projects. EPA Assistant Administrator for Water Jess Kramer was joined by states, water associations, technical assistance providers, and representatives from small communities to identify real actions that will be taken to ensure that infrastructure funding is invested efficiently and effectively to benefit Americans through stronger water infrastructure. Several actions specifically focused on addressing challenges that small communities face when applying for funding.
