ROLAND WWT Wastewater Treatment Plant, Sequoyah County, Oklahoma

ROLAND WWT is a municipal wastewater treatment facility located in Sequoyah County, Oklahoma, United States. The plant serves a population of about 2,842 residents, operating as part of the region's water infrastructure. Its location along US 64 places it within a rural setting in eastern Oklahoma. The plant provides secondary treatment, a standard level for communities of this size under the US Clean Water Act. With a designed capacity of 1,260.54 thousand cubic meters and an annual discharge volume of 946.35 thousand cubic meters, the facility operates within its capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids before discharge. The treated effluent is released into local waterways that drain into the Arkansas River basin, eventually reaching the Mississippi River and the Gulf of Mexico. The plant plays a role in protecting downstream water quality in this ecologically diverse region, which supports aquatic habitats and recreational uses.

The plant discharges into tributaries of the Arkansas River, which flows through Oklahoma and Arkansas before joining the Mississippi River. This watershed supports diverse aquatic life and is important for regional water supply. The downstream environment includes the Mississippi River Delta, a major ecological zone that provides critical habitat for migratory birds and fish species.
