In recent years, the growth of Hobbs, New Mexico, has required significant investment in the community wastewater utility to expand capacity and improve its effectiveness. BHI led a team to develop and improve the aerobic digester process at the 6.4 MGD rated Hobbs Water Reclamation Facility. The project included designing a similar system at a new location within the existing facility site to improve the system’s effectiveness. The challenge was creating a new digester to fit in the limited footprint. The team’s approach to this design was a unique, four-basin square grid that could expand to six basins with a central distribution box, allowing different configurations to work depending on the operator/maintenance needs. The BHI team also included a clean interior structure environment, increasing efficiency and preventing difficult maintenance situations.
