  1. Heavy Rain On Snow Is Testing Aging Dams Across Michigan And Wisconsin — This Is The Future In A Warming World 4/22/2026
    For much of Michigan and Wisconsin, as well as northern Illinois, 2026 has been the wettest March and April on record. The region’s aging water infrastructure was never designed for the volume of water it is facing. That’s a troubling sign for the future, with flooding becoming more common as global temperatures rise.
  2. Why Multi‑Commodity Utilities Need Smart Meter Data Management 4/22/2026

    Breaking down data silos allows multi-commodity utilities to improve operational efficiency and infrastructure visibility. By managing water and electric data on a shared platform, providers can detect leaks faster and support long-term conservation goals.

  3. Beyond Clarification: Optimizing Polyacrylamide Selection For High-Complexity Industrial Wastewater Treatment 4/21/2026
    Polyacrylamide (PAM) selection in industrial wastewater treatment is frequently reduced to a trial-and-error exercise, resulting in reagent waste, inconsistent effluent quality, and inflated operating costs. This article presents a structured framework for PAM optimization across three critical variables — ionic charge density, molecular weight, and coagulant synergy.
  4. The Industry Has Money, Technology, And Urgency — So Why Is Nothing Moving Faster? (7 Takeaways From The Water Week 2026 Press Conference) 4/20/2026

    The water industry faces a critical disconnect between available federal funding and project execution. As workforce shortages and regulatory risks accelerate, stakeholders must bridge the communication gap to ensure long-term resilience and infrastructure stability. Hear from Water Online's publisher, Travis Kennedy, about these topics and more that were discussed at Water Week 2026.

  5. When Growth Outpaces Infrastructure: How The City Of Conroe Built A Future-Forward Software-Defined Water System Ready For What's Next 4/20/2026
    For fast-growing cities, the challenge is no longer whether modernization is needed, but how to do it without increasing risk or complexity. The City of Conroe, Texas offers a clear example of what it looks like to modernize with intent, by addressing not just equipment, but the underlying architecture of water operations.
  6. Beyond Clarifiers: How Advanced Primary Filtration Solves Wet Weather Capacity Challenges 4/16/2026

    Pile cloth media filtration treats wet weather flows in real time, increasing capacity, improving removal efficiency, and helping utilities reduce reliance on limited stormwater storage.

  7. Precision Control In The Aeration Basin: A Case Study In Flow-Based DO Stabilization 4/14/2026

    Flow-based DO control and advanced blowers help stabilize aeration, reduce energy consumption, and improve treatment performance, turning a major wastewater cost center into an efficiency opportunity.

  8. Drinking Water Contaminated With 'Forever Chemicals' During Pregnancy Linked To An Increased Risk Of Childhood Asthma 4/13/2026

    While most of us are routinely exposed to low levels of PFAS, some communities are exposed to far higher levels from nearby pollution sources. A new study shows that in one of these at-risk communities, children were more likely to develop asthma if their mothers were exposed to very high PFAS levels during pregnancy.

  9. The Evolution Of Efficient Biosolids Solutions 4/13/2026

    Modern biosolids management requires sophisticated biological treatment to achieve Class A pathogen reduction and efficient solids destruction. Explore how integrated aerobic digestion and nutrient management technologies provide reliable, cost-effective paths toward regulatory compliance.

  10. The Pragmatic Shift In Source Water Protection: Moving From Symptom Management To Root-Cause Accountability 4/9/2026
    A shift in how we approach source water protection is long overdue. Currently, we are trapped in a cycle of escalating costs, forced to treat symptoms like algae and invasive weeds expediently with chemicals while the underlying risk in the reservoir compounds. True risk management requires breaking this cycle.
