Sevastopol SD 1 STP - Town of Sevastopol, Wisconsin Wastewater Treatment Plant

Sevastopol SD 1 STP is a municipal wastewater treatment plant located in the Town of Sevastopol, Door County, Wisconsin. Serving a population of 718, this facility is part of the region's infrastructure for managing domestic wastewater in a rural, coastal setting. The plant provides secondary treatment, which is the standard required by the US Clean Water Act for municipal facilities. With a designed capacity of 295.26 thousand gallons per day and an average discharge volume of 143.85 thousand gallons per day, it operates well within its capacity. The plant is situated within 10 km of Lake Michigan, a major freshwater resource. Treated effluent from the plant ultimately reaches Lake Michigan, part of the Great Lakes system. This watershed supports diverse aquatic life and provides drinking water for millions. The plant's coastal location necessitates careful management to protect the lake's water quality and ecological health.

The plant discharges into the Lake Michigan basin, which drains into the Great Lakes system and eventually the St. Lawrence River and Atlantic Ocean. Lake Michigan supports a rich ecosystem including native fish species and migratory birds. As a coastal facility, the plant must meet stringent nutrient and pathogen limits to prevent eutrophication and protect recreational waters.
