CENT KITSAP REG STP - Brownsville, Washington Wastewater Treatment Plant

CENT KITSAP REG STP is a municipal wastewater treatment facility located in Brownsville, Washington, within Kitsap County. The plant serves a population of approximately 44,476, placing it in the medium-agglomeration category under US regulatory standards. Its location in the Pacific Northwest region subjects it to local environmental regulations and oversight by the Washington State Department of Ecology. As a US facility of this scale, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which mandates secondary treatment as a minimum standard for municipal wastewater. The plant's discharge must comply with water quality standards set by the Clean Water Act to protect receiving waters. The plant is situated within 50 kilometers of the coast, indicating its discharge likely reaches the Puget Sound or a tributary thereof. The Puget Sound is a critical estuarine ecosystem supporting salmon, orcas, and diverse marine life. Effective treatment at this plant helps reduce nutrient loading and pollutant impacts on the sound's sensitive marine environment.

The plant's treated effluent likely discharges into a tributary of the Puget Sound, a large estuarine system in Washington that connects to the Pacific Ocean via the Strait of Juan de Fuca. The Puget Sound supports ecologically significant habitats, including eelgrass beds and salmon spawning grounds, which are sensitive to nutrient pollution and contaminants. The plant's location within 50 km of the coast underscores its potential influence on coastal water quality and marine ecosystem health.
