Sustainable Wastewater Solutions For Today's Challenges
3/13/2026
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.

How Water Utilities Can Foster Change — And Prioritize People
3/13/2026
Water and wastewater utilities are under pressure. Aging infrastructure, rapid population growth, and a retiring workforce are just a few of the challenges they face. Where do utilities turn for solutions? While technology solutions and new tools take center stage, a critical piece is often overlooked: the people.

Rethinking Aeration: Demand-Based DO Control And Energy Optimization
3/13/2026
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.
