HOLLAND SD 1 WWTP - Advanced Wastewater Treatment in Town of Holland, Wisconsin

HOLLAND SD 1 WWTP is a municipal wastewater treatment facility located in the Town of Holland, Brown County, Wisconsin. It serves a small population of approximately 325 residents, reflecting its role in a rural community. The plant is part of the state's wastewater infrastructure managed under the Clean Water Act. The facility employs advanced treatment processes, ensuring high-quality effluent before discharge. With a designed capacity of 1,476.31 cubic meters per day and an average discharge volume of 832.79 cubic meters per day, it operates well within its capacity. As a small plant in the United States, it is subject to EPA NPDES permitting and Wisconsin Department of Natural Resources oversight. The plant discharges into a local waterway that drains into the Fox River, which flows into Green Bay on Lake Michigan. This inland location minimizes direct coastal impact, but the plant's advanced treatment helps protect the downstream aquatic ecosystem, including Lake Michigan's diverse fish populations and migratory birds.

The plant's treated effluent enters a tributary of the Fox River, which flows northward into Green Bay, an arm of Lake Michigan. Lake Michigan supports a complex food web, including lake trout, whitefish, and migratory species. The advanced treatment level reduces nutrient loading, helping to prevent algal blooms and maintain water quality in this ecologically sensitive Great Lakes basin.
