The Acorns That Helped Overhaul A Small Rural Drinking Water System
While no major municipal water utility has ever claimed to be overfunded, it is much easier to cover the cost of large projects when it can be spread across hundreds of thousands of residents. But this is a stark contrast to the mathematical reality of smaller utilities like the Madison Community Services District (CSD). Its small size can make it difficult to attract the attention of those who control the purse strings for major projects.  Continue Reading..

Understanding Biofilm Through Oxidative Chemistry
Biofilm is one of those water treatment problems that can look deceptively simple. Microorganisms attach to a surface, multiply, and begin building a community. The natural response is to disinfect, apply enough oxidant to kill the organisms and maintain a residual strong enough to keep them under control, however in practice, it is rarely that straightforward.  Continue Reading..

Understanding Biofilm Through Oxidative Processes
Controlling a mature biofilm means targeting its protective matrix, not only the organisms inside. Prevention, destabilization, and removal each call for different oxidative behaviors, changing how performance should be judged.  Continue Reading..

Understanding Biofilm Through Oxidative Diversity
Comparing oxidants by strength alone overlooks how different reactive species work together inside biofilm, and why familiar performance metrics only partly capture oxidative effectiveness.  Continue Reading..

Understanding Biofilm Through Oxidative Control Strategies
A disinfectant residual can look adequate while biofilm persists. The reactive chemistry an oxidant creates in water, and its interaction with the biofilm matrix, may matter more than oxidant strength.  Continue Reading..

The $1.5 Million Sewer Repair — And The Water-Quality Evidence Missing Upstream
A documented series of corrosive industrial discharges reveals why the costliest monitoring failure can be an unexplained, repeated process condition — not an absent alarm.  Continue Reading..

How Industrial Facilities Are Rethinking Wastewater Treatment And Water Reuse As Discharge Rules And Operating Costs Tighten
Industrial facilities are under pressure to reduce freshwater consumption, control wastewater discharge costs, and maintain reliable production. Water reuse can help address all three concerns, but recovering water does not automatically make a facility more efficient.  Continue Reading..

Predicting Pump Ragging Before The Overflow: What Lift-Station Sensing Gets Right
Rags and wipes don’t seize a pump overnight they load it gradually, and the sensors already in the station can see it coming days ahead. The stations that avoid overflows aren’t the ones with the most instruments; they’re the ones that read the right signals together.  Continue Reading..

Tackling Lake Erie's Algal Blooms Requires Targeted Conservation Strategies
Algal blooms in Lake Erie remind us how closely food production and clean water are connected. Many of these nutrients come from nearby farms, and the challenge is keeping them out of waterways.  Continue Reading..

El Niño Intensifies: Collection Systems Should Prepare Now
A strengthening El Niño raises the stakes for sewer and stormwater networks, making monitoring of rainfall, level, and flow before the first major storm a matter of readiness rather than reaction.  Continue Reading..
