  1. Illegal Wastewater Discharges And The Importance Of Organics Monitoring In Municipal Sewer Networks 9/7/2026

    Unpredictable industrial dumping overloads municipal wastewater treatment systems, driving up utility costs. Continuous inline monitoring provides real-time visibility into shifting organic loads, enabling collection teams to catch contamination spikes early and protect downstream biological processes.

  2. The High Cost Of Dirty Data In Wastewater Automation 9/4/2026

    High-frequency radar provides reliable wastewater level measurement that strengthens digital twins, predictive analytics, and automated collection systems while reducing sensor maintenance.

  3. Beyond The Screen: Why Debris Management Deserves More Attention 9/4/2026

    Evolving debris characteristics and aging collection infrastructure place unprecedented operational stress on downstream equipment. Evaluating preliminary treatment efficiency helps facilities eliminate chronic maintenance demands, safeguard critical infrastructure, and protect operating budgets.

  4. 5 Questions To Ask Before Reusing Clarifier Specifications 9/4/2026

    Reusing master equipment specifications without evaluating application-specific hydraulics or basin geometries creates costly mechanical conflicts. Auditing legacy requirements ensures every structural and operational component directly supports site-specific treatment goals.

  5. Renewable Biogas From Wastewater Treatment: A Critical Pathway To Net Zero 9/4/2026

    Converting organic wastewater residuals into methane-rich biogas creates a circular energy system. Modernizing digester mixing, thermal management, and gas containment reduces grid dependency, lowers facility operating expenses, and advances net-zero decarbonization goals.

  6. PFAS Funding Is Flowing — But Does The Water Sector Have Enough People To Deliver It? 9/4/2026
    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.
  7. Why Water Utilities Need Better Asset History, Not Just More Maintenance Data 9/4/2026

    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.

  8. Sunscreen For Lakes And Dams: Could A Thin Floating Layer Of Nanomaterial Shield Water From Evaporation? 9/3/2026

    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 limiting the amount of infrared heat from the sun that reaches the water. He also outlines what hurdles need to be cleared for the design to be tested in the real world.

  9. Many Cities Buried Urban Streams. Here's How To Bring Them Back 9/1/2026

    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 walkable public spaces.

  10. Inside Zero Liquid Discharge Systems: The Technology Driving Industrial Water Reuse 8/28/2026
    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.
