Sandhill WWTP - Four Corners, Florida Wastewater Treatment Plant

Sandhill WWTP is a municipal wastewater treatment facility located in Four Corners, Florida, a rapidly growing community in Osceola County. The plant serves an estimated population of 25,000, placing it in the medium-agglomeration category for U.S. facilities. As a U.S. wastewater plant, Sandhill WWTP operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Florida Department of Environmental Protection. For plants serving this population size, secondary treatment is typically required, with additional nutrient removal standards applicable in sensitive watersheds like those feeding into the Greater Everglades ecosystem. The plant's treated effluent likely discharges into local surface waters that drain into the Kissimmee River basin, eventually reaching Lake Okeechobee and the Caloosahatchee or St. Lucie estuaries. This watershed is ecologically significant, supporting diverse aquatic life and serving as a critical component of Florida's water supply and Everglades restoration efforts.

Sandhill WWTP is situated in the Kissimmee River basin, which drains south into Lake Okeechobee, Florida's largest freshwater lake. From there, water flows via the Caloosahatchee River to the Gulf of Mexico or via the St. Lucie River to the Atlantic Ocean. This watershed is ecologically sensitive, supporting diverse aquatic habitats and serving as a vital corridor for migratory birds and fish species. Nutrient management is particularly important in this region to prevent harmful algal blooms in downstream water bodies.
