Do Water Meters Still Need External Transmitters?
5/1/2026
Expectations for transparency and reliability in water-metering infrastructure have risen. As a result, a fundamental question is emerging across the industry: if modern ultrasonic meters are already smart, why are we still adding intelligence outside the meter?

Powdered Activated Carbon: A Flexible Tool For Targeted Treatment Challenges
5/1/2026
Treatment plants most often deploy carbon in two forms: granular activated carbon (GAC) and powdered activated carbon (PAC). While GAC is widely used for steady-state, long-term contaminant control, PAC offers an alternative, versatile, rapid-response approach. In these six scenarios, PAC is the ideal solution.

Eradicating High-Strength Nitrogen Loads Without Expanding Your Aeration Basins
5/1/2026
When decision-makers assess the best ways to deal with high-strength nitrogen loads in their wastewater treatment plants, an important thing for them to remember is that biological treatment methods alone typically cannot handle all of a facility’s nutrient load. Instead, they should consider how a combination of physical-chemical extraction methods can provide an extremely reliable, small footprint method for handling above-average loads.

Applying Two Flood Models To Cross-Check And Improve Each Other β And Maybe Saving A Downstream Village In The Process
5/1/2026
Getting a second opinion is a time-tested piece of wisdom. During a recent project for a municipal water supply utility, we found that this advice also applies to modeling the effects storms have on the municipality’s reservoirs and dams, and the potential flooding impacts downstream of the dams.

How Satellite IoT Can Enhance Remote Water System Monitoring
5/1/2026
There is a noticeable shift in how monitoring data is being treated across the water sector. It is no longer something that sits quietly in the background of operations, collected for compliance, and reviewed periodically. It is being examined more closely, and more often, by a wider set of stakeholders.

The Hidden Legionella Risk In Closed-Loop Systems
4/27/2026
For a long time, itβs been assumed that closed-loop water systems β those commonly found in building heating systems, air-conditioning units, and cooling systems β are at a low risk for Legionella. However, there are many reasons why closed-loop systems can actually inadvertently promote the risk of Legionella.

Common AMI Implementation Mistakes And How To Avoid Them
4/23/2026
The journey from manual water-meter reads to a fully integrated digital ecosystem is long and complex. To help utilities along, the Smart Water Networks Forum (SWAN) released the global Smart Metering Playbook, which includes both implementation best practices and common pitfalls. Here are five common advanced metering infrastructure (AMI) rollout mistakes from the Playbook, along with examples of how to overcome them.
