Santa Isabel WWTP is a municipal wastewater treatment facility serving the community of Santa Isabel, Puerto Rico, with a population of approximately 33,493. The plant is situated in the sector El Río, near Boca Velázquez, and plays a key role in managing wastewater for this coastal municipality. The plant operates under the US Clean Water Act, administered by the EPA and the Puerto Rico Environmental Quality Board. For a community of this size, secondary treatment is typically required, and the plant's designed capacity of 1.00 million gallons per day suggests it is sized to handle the local wastewater load. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Caribbean Sea. This coastal discharge requires careful management to protect marine ecosystems, including coral reefs and seagrass beds that are sensitive to nutrient pollution. The plant's location within 50 km of the coast underscores the importance of effective treatment to safeguard downstream water quality.

The Santa Isabel WWTP discharges into the local river system that flows into the Caribbean Sea near the southern coast of Puerto Rico. This coastal zone supports diverse marine life, including coral reefs and mangroves, which are sensitive to nutrient enrichment and pollutants. Proper wastewater treatment is essential to prevent eutrophication and protect the ecological health of the surrounding waters.
