Geomembrane Liner Selection For Municipal Wastewater Lagoons: HDPE vs. LLDPE vs. RPP — A Field Installer's Perspective
High-density polyethylene (HDPE), linear low-density polyethylene (LLDPE), and reinforced polypropylene (RPP), among other materials, all show up on municipal wastewater and manure lagoon liner projects. Each of these lagoon liners has a place, and the differences aren't just chemistry on a datasheet; they show up physically on site.  Continue Reading..

Brackish Water Desalination: A Strategic Imperative For Sustainable Water Stewardship Across The American Water 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..

From Study To Startup: Reliability Lessons From A CVWRF Headworks Project
Wastewater utilities invest significant time and resources in capital projects intended to improve reliability, capacity, safety, and long-term performance. The design may be sound, the equipment may be new, and the project may appear ready for service. Yet the true test often comes during startup.  Continue Reading..

Market Intelo Forecasts Continued Growth In Global Water Purification Systems Market

Water is crucial for people’s health and safety, industry, and the environment. In many cases, urban populations and industries continue to grow, increasing the burden on municipalities and industries to deliver clean and safe water meeting new quality specifications, and in conjunction with regulations that focus on a higher quality of water, a tighter level of discharge control, and a higher degree of resource conservation. Many municipalities and industries are moving forward with using modern, high efficiency membrane filtration technologies to achieve higher efficiencies, better removal, and improved performance.

IDE Water Solutions North America Selected To Supply Pulse Flow Reverse Osmosis (PFRO) System To Horizon Regional Municipal Utility District

Today, IDE Water Solutions North America, Inc., a leading provider of water treatment solutions, announces its partnership with Horizon Regional Municipal Utility District (Horizon MUD) to deliver an advanced water treatment facility, including a sophisticated Pulse Flow Reverse Osmosis (PFRO) system. This project, to be implemented with engineering partner, TRE & Associates, will address water scarcity in Horizon City, Texas, outside of El Paso, and is capable of delivering 4.2 million gallons of water per day (MGD) – supplying the high-quality drinking water residents need.

EPA Advances Cooperative Federalism With Potential Approach For Coal Combustion Residuals Permitting Program

Today, U.S. Environmental Protection Agency (EPA) is seeking public input on a potential new regulatory approach for addressing certain coal combustion residuals (CCR) units as the agency explores pathways that promote cooperative federalism, reduce regulatory uncertainty, eliminate unnecessary permitting delays, and promote electric grid reliability while ensuring a high standard of environmental protection.
