The facility serves a small population of 456 residents, reflecting the rural character of the community. As an advanced treatment plant, it provides a higher level of pollutant removal than conventional secondary treatment, ensuring compliance with stringent water quality standards. The plant has a designed capacity of 454.25 volume units and currently discharges approximately 340.69 volume units of treated effluent. The advanced treatment level indicates the use of technologies such as filtration, nutrient removal, or disinfection.

The plant's advanced treatment helps minimize nutrient loading and other pollutants, contributing to the ecological health of the Sheboygan River and Lake Michigan.

Waldo WWTP discharges into the Sheboygan River basin, which flows into Lake Michigan, one of the largest freshwater lakes in the world. The watershed supports diverse aquatic habitats, including coldwater fisheries and migratory bird routes. Advanced treatment at the plant reduces nutrient and pollutant loads, helping to protect Lake Michigan from eutrophication and harmful algal blooms.
