Queen City WWTP - Secondary Treatment Plant in Queen City, Texas

Queen City WWTP is a municipal wastewater treatment facility located in Queen City, Texas, a small community in Cass County near the Texas-Arkansas border. The plant serves a population of approximately 1,400 residents, reflecting the scale of a small rural agglomeration. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater facilities. With a designed capacity of 946.35 thousand cubic meters per year and an actual discharge volume of 605.67 thousand cubic meters, the plant operates below its design capacity, indicating room for future growth or seasonal variability. The treated effluent from Queen City WWTP is discharged into local waterways that ultimately drain into the Red River basin, a major tributary of the Mississippi River. This downstream connection to the Gulf of Mexico underscores the plant's role in protecting water quality in a region characterized by forested watersheds and agricultural land use.

The plant's discharge enters local creeks that flow into the Red River, which then joins the Mississippi River and empties into the Gulf of Mexico. This watershed supports diverse aquatic life and provides habitat for migratory fish species. The plant's secondary treatment helps reduce organic pollutants and suspended solids, mitigating impacts on downstream ecosystems.
