It serves a population of approximately 6,419 people, placing it in the small to medium community category. The plant is situated inland, away from coastal areas, and its operations are subject to the Clean Water Act and state-level permitting through the Arkansas Department of Energy and Environment. As a facility serving fewer than 10,000 people, the plant is expected to meet secondary treatment standards under the Clean Water Act. Typical plants of this scale in Arkansas employ activated sludge or lagoon systems to achieve required effluent limits. Regulatory compliance is ensured through National Pollutant Discharge Elimination System (NPDES) permits. The treated effluent from Hope Bois D Arc WWTP ultimately discharges into local waterways that drain into the Red River basin, which flows south to the Mississippi River and into the Gulf of Mexico. The plant plays a role in protecting water quality in the region's streams and rivers, which support aquatic life and are used for recreation and agriculture.

The plant's discharge enters local tributaries that feed into the Red River, a major waterway in the southern United States. The Red River flows through Arkansas, Texas, Oklahoma, and Louisiana before joining the Mississippi River and emptying into the Gulf of Mexico. This watershed supports diverse aquatic ecosystems, including fish and migratory bird populations. The plant's treatment helps maintain water quality in these downstream environments, which are important for regional biodiversity and human use.
