How To Remove FOG Deposits And Prevent Sewer Overflow
Fats, oils, and grease (FOG) deposits present a problem for the wastewater industry as they create sewer lines blockages that lead to overflow. Digester systems can successfully remove these deposits with the latest environmentally friendly technology by breaking them down into microparticulates. This paper offers a technical review of the solutions available for applications such as commercial and residential lift stations, grease traps, and wet wells.

Pilot Studies In North Carolina With Hydrex™ Odor Solutions
Two municipalities were faced with odor issues and required corrosion prevention in their collection systems. Monitoring in the sewer lines indicated peak H2S atmospheric concentrations of 300-500 ppm. Both clients desired H2S < 20 mg/L to prevent corrosion and preferably lower to prevent H2S odor.

Advancing The Potential For Stormwater Reuse: Investigation Of Water Quality And Treatment
Managing stormwater runoff is a complex environmental challenge for communities across the country. As stormwater runoff flows into nearby waterways, it can collect various pollutants including trash, chemicals, oils, and dirt, which can lead to environmental and public health impacts.

The Challenge Of Flow Disturbances On Meter Accuracy
Accurately measuring flow is critical for water utility operations. Also, regulatory agencies mandate flow monitoring and require annual calibration of meters. But even a meter in perfect condition and properly calibrated can read inaccurately. Flow disturbances are a common cause of accuracy and repeatability errors.

Understanding The Different Phosphorus Tests
In wastewater treatment, phosphorus testing can quickly become confusing. For example, there are three different tests. So, which test was performed? Test results can be displayed in two different forms. So, which form was utilized? Tests can measure both particulate and dissolved phosphorus. So, was the sample filtered?

LATEST INSIGHTS ON WASTEWATER

Einstein once said of compound interest, "He who understands it, earns it. He who doesn't, pays it." The same logic of compounding applies to the organic sediment accumulating on the floor of your drinking water reservoir. The longer you wait to address it, the more exponentially expensive it becomes to fix.
-
Our infrastructure systems have operated in managed deterioration for decades. And not surprisingly, once they deteriorate badly enough and cross over into active failure, all cost discipline disappears.
-
Every day, food scraps disappear into trash bags, are hauled away, and forgotten. But that waste could be turned into something productive.
-
Currently, water infrastructure is outdated and fragile, prone to breakages and leaks. Reactive approaches to water infrastructure are only implemented after an incident and are more expensive than simple maintenance fixes. Geotechnical Internet of Things (IoT) devices enable water and wastewater industry professionals to identify and address issues before they escalate into catastrophic events.
-
Traditional gravity sewers rely on large-diameter mains, deep trenches, and often multiple lift stations — elements that carry significant capital and restoration costs, particularly in rural or rugged terrain. To improve cost efficiency and sustainability, many municipalities are adopting decentralized collection systems such as Septic Tank Effluent Pump (STEP) systems, Septic Tank Effluent Gravity (STEG) systems, and liquid-only sewers.
-
Aeration control strategies often remain conservative and static. Blowers operate continuously, oxygen levels are maintained near maximum, and airflow rates are rarely adjusted in response to real-time biological demand. The result is widespread over-aeration — a condition that does not improve treatment performance but significantly increases operating costs.
