OCHELATA UA WWT - Wastewater Treatment Plant in Washington County, Oklahoma

OCHELATA UA WWT is a municipal wastewater treatment facility located in Washington County, Oklahoma, serving a small population of 424 residents. The plant operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal wastewater discharges. The plant has a designed capacity of 253.62 million gallons per year and currently treats an annual discharge volume of 246.05 million gallons. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The treated effluent is released into local surface waters that drain into the Caney River watershed, part of the Arkansas River basin. This region supports diverse aquatic life and is important for regional water quality management. The plant's inland location reduces direct marine impact, but its discharge affects freshwater ecosystems.

The plant discharges into local streams that flow into the Caney River, a tributary of the Arkansas River, which ultimately drains into the Mississippi River and the Gulf of Mexico. The watershed supports a variety of fish and wildlife, and maintaining water quality is essential for ecological health and downstream uses.
