Fleet Circularity: Closed-Loop Vehicle Detailing
In Nashville, Tennessee, we partnered with Cox Manheim to transform industrial fleet washing from a drain on resources into a closed-loop asset. We deployed the Ginseng to tackle high-volume wash effluent—heavy in particulates, road grime, and surfactants. Instead of a single-use discharge, our technology treated and returned the water directly to the wash lines.
The deployment proves that high-throughput logistics can operate sustainably. The system maintains rigorous wash-quality standards while reducing the facility's municipal water intake, validating a scalable model for fleet circularity.
Contaminant Removal
The ceramic barrier achieves >99% removal of TSS and turbidity, while also providing high removal of TDS and hardness to ensure recycled water protects vehicle finishes and prevents nozzle clogging.
Water Recovery
The system operates with high efficiency, targeting ~70% water recovery, keeping the wash lines running while minimizing net water consumption.
This case study documents the deployment of a containerized water treatment system at a fleet and logistics facility operated by Cox Enterprises in Nashville, Tennessee. The facility required an on-site water reuse system capable of treating high-volume vehicle wash and fleet maintenance wastewater to reuse standards, reducing dependency on municipal water supply and eliminating ongoing third-party wastewater hauling costs.
The ginseng modular wastewater treatment system was deployed to treat wash water, oils, and suspended solids generated by large-scale fleet vehicle processing operations. The system enables closed-loop water recycling across the facility, turning a daily wastewater liability into a continuously reusable operational asset.
Key capabilities deployed include containerized ultrafiltration water treatment, automated maintenance alerts, remote visualization, and One Service subscription support. This deployment serves as a reference case for fleet and logistics wastewater treatment, car wash water recycling systems, and modular water reuse technology in high-throughput vehicle processing environments.
