Harrison WWTP - Municipal Wastewater Treatment in Harrison, Arkansas

Harrison WWTP is a municipal wastewater treatment facility located in Harrison, Arkansas, serving a population of around 13,397. The plant is situated in the Ozark region, an area characterized by karst topography and sensitive watersheds. As a medium-sized agglomeration, the facility plays a key role in managing local wastewater and protecting downstream water quality. Under the US Clean Water Act, municipal wastewater treatment plants are required to meet secondary treatment standards, which typically involve biological processes to remove organic matter and suspended solids. The regulatory framework ensures that facilities of this size achieve effluent quality sufficient to protect receiving waters. The population served suggests a moderate-scale operation. The treated effluent from Harrison WWTP likely discharges into a tributary of the White River, which flows through northern Arkansas and eventually into the Mississippi River. The White River basin supports diverse aquatic life, including several species of freshwater mussels and fish. The plant's location inland, over 50 km from the coast, reduces direct marine impact, but its discharge contributes to the overall health of the river ecosystem.

Harrison WWTP discharges into the White River watershed, which drains into the Mississippi River and ultimately the Gulf of Mexico. The White River is a major waterway in Arkansas, supporting diverse aquatic habitats including mussel beds and fish spawning grounds. The region's karst geology makes groundwater particularly vulnerable to contamination, emphasizing the importance of effective wastewater treatment to protect both surface and subsurface water resources.
