Activated sludge and clarifiers: wastewater treatment plants in New Mexico
16 plants · 52% of the state · 16 MGD reported by 9 plants
Klarifi identifies 16 publicly owned wastewater treatment plants with activated sludge and clarifiers in New Mexico, 52% of the 31 plants in the state (16 MGD reported by 9 plants). The largest is City Of Farmington in Farmington at 6.33 MGD.
Activated sludge is the standard mechanical process for cities: aeration basins where bacteria consume organic matter, followed by clarifiers that settle the biomass out. These plants are identified by their circular or rectangular clarifiers and by the suspended-growth process code, and they are the main market for blowers, diffusers, clarifier mechanisms and instrumentation.

Sources and methodology
Flow, permit and violation figures come from the EPA's ICIS-NPDES discharge monitoring records. Population served comes from the Clean Watersheds Needs Survey 2022. Treatment structures are identified by Klarifi's review of aerial imagery, and capital improvement projects are extracted from published municipal budget documents. Violations are counted over the last three years of monitoring reports.
