The plant serves a population of about 3,628 people, classifying it as a small to medium-sized community system. It is situated inland, approximately 50 kilometers from the Pacific coast, and its operations are regulated under the U.S. Clean Water Act through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant has a designed capacity of 1.00 million gallons per day, indicating its scale relative to the local population.

Treated effluent from Buellton WWTF likely discharges into a local waterway within the Santa Ynez River watershed, which flows westward to the Pacific Ocean. The receiving water body supports aquatic life and contributes to the region's water resources. The plant plays a key role in protecting downstream ecosystems and maintaining water quality in the semi-arid coastal environment of Southern California.

The plant's discharge enters the Santa Ynez River basin, which drains into the Pacific Ocean near Lompoc. This watershed supports diverse aquatic habitats, including steelhead trout populations and riparian corridors. The region's Mediterranean climate with seasonal rainfall means that maintaining low-nutrient effluent is critical to prevent algal blooms and protect downstream marine environments.
