Anaerobic digesters and biogas: wastewater treatment plants in Texas
68 plants · 5% of the state · 864 MGD reported by 62 plants
Klarifi identifies 68 publicly owned wastewater treatment plants with anaerobic digesters and biogas in Texas, 5% of the 1,244 plants in the state (864 MGD reported by 62 plants). The largest is Village Creek Reclamation Facility in Arlington at 147.27 MGD.
Anaerobic digesters stabilise sludge in sealed heated tanks and produce biogas, visible from the air as digester silos and gas holders. Plants with digesters are typically above 5 MGD and are the buyers of mixing, heating, gas handling, cogeneration and dewatering equipment.

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.
