Hayward WWTP - Municipal Wastewater Treatment in Hayward, Wisconsin

Hayward WWTP is a municipal wastewater treatment facility located on Dyno Drive in Hayward, Sawyer County, Wisconsin. It serves a population of about 3,451 residents, placing it in the small agglomeration category typical of rural communities in the upper Midwest. As a US-based plant, Hayward WWTP operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, administered by the Wisconsin Department of Natural Resources. For small communities, secondary treatment is the standard requirement to reduce organic pollutants and suspended solids before discharge. The plant's treated effluent enters the local watershed, which drains into the Chippewa River system and ultimately reaches the Mississippi River. This connection highlights the plant's role in protecting downstream aquatic ecosystems and maintaining water quality in the broader Mississippi River basin.

Hayward WWTP discharges into the local watershed, which flows into the Chippewa River, a tributary of the Mississippi River. The downstream environment supports diverse aquatic life, including fish species such as walleye and smallmouth bass, and provides habitat for migratory waterfowl. The plant's treatment helps reduce nutrient loading and protects water quality in this ecologically sensitive region.
