Water Online Highlights

  1. 15 Years Of Experience With Laminar Flow, Sludge Activating, And Lagoon Aeration 9/9/2026

    In 2010 a unique, patented wastewater lagoon aerator was introduced to the industry. The presentation will consist of a number of ‘proof statements’ showing successes of this new technology.

  2. What Utilities Don't Know About GAC Reuse For PFAS 9/9/2026

    For utilities building PFAS treatment systems, thermal reactivation of spent granular activated carbon (GAC) may sound like the obvious answer. However, service provider availability and location, specific media acceptance criteria including quantity thresholds, restrictions on GAC type and condition, and regulatory uncertainty can all determine whether reuse is a viable option. 

  3. Passing vs Chopping: Understanding The Tradeoffs In Wastewater Collection And Transport 9/9/2026

    This presentation explores the tradeoffs between passing solids and macerating them, highlighting where each approach provides advantages and how emerging pump, cutter, and impeller technologies are reshaping solids handling strategies.

  4. Energy Savings With Efficient Blowers And Process Controls 9/9/2026

    Energy-efficient blowers, combined with aeration controls, reduce power costs and optimize aeration performance in wastewater plants.

  5. Beyond Water-Stress Scores: Assessing Infrastructure Resilience At The Asset Level 9/9/2026

    Water-stress screening can identify where an infrastructure asset deserves closer attention. Assessing resilience requires further steps: understanding the asset’s water profile, the reliability and security of its supply, the pressure it places on local resources, and whether adaptation can keep it operational and economically viable over time.

  6. Colorado River Conservation Depends On The Delivery System 9/8/2026

    The Department of the Interior issued the 2027-2028 Operating Guidelines, calling for Lower Basin deliveries to drop by 1.25 million acre-feet annually in 2027 and 2028, with a minimum of 700,000 acre-feet of additional voluntary conservation over those two years. While temporary reductions are a start, water districts and water professionals should also consider delivery upgrades and on-farm improvements in agricultural areas that prepare growers for a new reality with less water.

  7. No Easy Way To Add Supply: Bozeman Chooses Continuous Acoustic Monitoring 9/7/2026

    When water rights are fixed, capturing underground leakage is critical. Continuous acoustic monitoring identifies developing pipeline vulnerabilities early, reducing leak runtimes from months to days, cutting non-revenue water waste, and saving thousands in emergency repair costs.

  8. Don't Ditch The Ditch: New Oxidation Ditch Technologies Enhance Nutrient Removal 9/7/2026

    Advanced oxidation ditches combine multichannel treatment, efficient aeration, and smart controls to improve nutrient removal while reducing energy use, maintenance, and infrastructure requirements.

  9. 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.

  10. 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.
