HOLLAND WTF Wastewater Treatment Plant, Holland, Michigan

HOLLAND WTF is a municipal wastewater treatment plant located at 42 South River Avenue in Holland, Michigan, within Ottawa County. The plant serves a population of approximately 54,346, placing it in the medium-to-large agglomeration category for US facilities. Its location near the eastern shore of Lake Michigan places it within a sensitive Great Lakes watershed. As a US facility, HOLLAND WTF operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, typically administered by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). For a plant serving over 50,000 people, secondary treatment is the minimum federal standard, with potential additional requirements for nutrient removal to protect the Great Lakes from eutrophication. The plant's treated effluent ultimately reaches Lake Michigan, a vital freshwater resource that supports drinking water supplies, recreation, and diverse aquatic ecosystems. The Lake Michigan basin is ecologically significant, hosting species such as lake trout and whitefish, and is a major migratory corridor for birds. Protecting water quality in this basin is critical for both environmental and economic reasons.

HOLLAND WTF discharges into the Lake Michigan watershed, part of the Great Lakes system, which drains through the St. Lawrence River to the Atlantic Ocean. Lake Michigan is a large freshwater lake that supports diverse aquatic life, including fish species like lake trout and yellow perch, and provides habitat for migratory waterfowl. The region's coastal dunes and wetlands are ecologically sensitive areas that benefit from effective wastewater treatment to prevent nutrient pollution and algal blooms.
