Naples WWTP - Secondary Wastewater Treatment in Naples, Texas

Naples WWTP is a municipal wastewater treatment plant located in Naples, Morris County, Texas, United States. The facility serves a population of approximately 1,650 residents, reflecting its role as a small-scale treatment operation for this rural community in northeastern Texas. The plant provides secondary treatment, a standard level of purification that removes biodegradable organic matter and suspended solids. With a designed capacity of 946.35 thousand cubic meters per year and an actual discharge volume of 492.10 thousand cubic meters, the plant operates at roughly half its capacity. As a US facility, it falls under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent is discharged into local waterways that drain into the Cypress Creek basin, ultimately flowing toward the Red River and the Mississippi River system. This connection to the Gulf of Mexico underscores the plant's role in maintaining downstream water quality in a region characterized by forested watersheds and agricultural land use.

The plant's discharge enters local tributaries of Cypress Creek, which flows into the Red River and eventually the Mississippi River before reaching the Gulf of Mexico. This watershed supports diverse aquatic life, including fish species such as catfish and bass, and provides habitat for migratory waterfowl. The surrounding area is primarily rural with mixed forest and farmland, making nutrient management important to prevent algal blooms in downstream water bodies.
