Overview
San Juan WWTP serves approximately 25,000 residents in San Juan, Texas. The plant operates under the U.S. Clean Water Act, which mandates secondary treatment for municipal wastewater facilities.
San Juan WWTP is a municipal wastewater treatment facility located in San Juan, Texas, serving a population of about 25,000. The plant is situated in Hidalgo County, part of the Rio Grande Valley region, and plays a key role in managing local wastewater. As a U.S. facility, the plant is subject to the Clean Water Act and National Pollutant Discharge Elimination System (NPDES) permitting. For a plant serving 25,000 people, secondary treatment is typically required, and the permit would include effluent limits for biochemical oxygen demand, total suspended solids, and other parameters. The plant's treated effluent likely discharges to a local waterway that drains into the Rio Grande or directly to the river, which flows into the Gulf of Mexico. The Rio Grande is a critical water source for agriculture and communities in the region, and its water quality is important for downstream ecosystems, including estuaries and coastal habitats.
Environmental context
The plant is located in the Rio Grande Valley, a semi-arid region dependent on the Rio Grande for irrigation and drinking water. Treated effluent likely enters the Rio Grande or a tributary, eventually reaching the Gulf of Mexico. The river supports diverse aquatic life and is a vital migratory corridor for birds. Protecting water quality is essential for downstream ecosystems, including the Laguna Madre and Gulf Coast wetlands.
