90 Days to Undo 30 Years: Texas City Saves $1 Million Reversing a Wastewater Crisis

STOCKDALE, Texas — For three decades, sludge had been quietly winning. By last fall, it had packed nearly six feet deep into Stockdale’s primary wastewater lagoon.  It was thick enough to threaten EPA compliance, choke treatment capacity, and force the city toward a $1.5 million dredging project that would have sent 350 truckloads of waste through residential streets.

City Manager Stephen Mayfield chose a different path. Working with E3 Entegral Solutions, Stockdale deployed Nano Gas Environmental’s mobile nanobubble oxygenation system in September 2025. By December, sludge in the main lagoon had dropped from 5.8 feet to under one foot. City wastewater treatment never shut down. No trucks. No excavation. Cost savings of approximately $1 million compared to conventional dredging.

The technology works by pumping trillions of microscopic oxygen bubbles into the water column, accelerating natural bacterial digestion of organic solids at 4 to 8 times the rate of standard aeration. A lagoon crawler broke up decades of compacted material so treatment could reach buried layers. Within the same period, secondary lagoons saw 50% sludge reduction without any direct intervention.  Cleaner outflow from Lagoon 1 did the work downstream. Total suspended solids dropped 95%. Ammonia fell 87%.

“Dredging, it’s very expensive,” Mayfield said. “Would I recommend this to other municipalities? Absolutely yes. We now have future development capacity.”

Nano Gas Environmental CEO Len Bland sees Stockdale as proof of concept for a problem that runs far deeper than one Texas town. Thousands of U.S. municipalities operate aging lagoon systems, many approaching the same compliance cliff Stockdale was facing. Traditional Dredging, dewatering, and disposal have always meant months of disruption and millions spent..

“This project proves that nanobubble technology doesn’t just treat the symptom,” Bland said. “It reverses the damage, fast, at a fraction of the cost.”

The company is expanding pilot deployments and commercial discussions with municipalities and wastewater operators nationwide. Its platform requires no permanent infrastructure and deploys across municipal, industrial, agricultural, and environmental remediation applications.
