Eureka Springs WWTP - Municipal Wastewater Treatment in Eureka Springs, Arkansas

Eureka Springs WWTP is a municipal wastewater treatment facility located in Eureka Springs, Arkansas, a small city in the Ozark Mountains. The plant serves a population of approximately 2,073 residents, reflecting the scale of a small community treatment system. Under the US Clean Water Act, plants of this size are typically required to meet secondary treatment standards through the National Pollutant Discharge Elimination System (NPDES) permit program. The regulatory framework ensures that effluent quality meets state and federal standards for the protection of receiving waters. The plant discharges into local streams that are part of the White River watershed, which ultimately flows into the Mississippi River and the Gulf of Mexico. The Ozark region is known for its karst topography and sensitive aquatic ecosystems, making proper wastewater treatment essential for protecting groundwater and surface water quality.

The plant's discharge enters tributaries of the White River, a major waterway in the Ozarks that supports diverse aquatic life and recreational uses. The White River flows into the Mississippi River, which drains to the Gulf of Mexico. The region's karst geology makes groundwater particularly vulnerable to contamination, emphasizing the importance of effective treatment.
