The Rio Grande flows through arid and semi-arid regions, making water quality management critical for downstream ecosystems and human use. The river supports species such as the Rio Grande silvery minnow and provides habitat for migratory birds. The plant's secondary treatment helps protect this sensitive watershed from nutrient pollution and pathogens.
