The plant is situated in Muscatine County, near the Mississippi River, and operates under the regulatory framework of the U.S. Clean Water Act. The plant provides secondary treatment, which is the standard level required by the U.S. EPA for municipal wastewater facilities. With a designed capacity of 340.69 units (likely thousand gallons per day), it operates at full capacity based on reported discharge volumes. As a small-scale facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Iowa Department of Natural Resources. The treated effluent from MONTPELIER SD ultimately drains into the Mississippi River via local streams and tributaries. The Mississippi River is a major ecological corridor supporting diverse aquatic life and migratory birds. The plant's discharge contributes to the overall water quality management of this vital river system.

The plant discharges into local waterways that flow into the Mississippi River, one of the largest river systems in North America. The Mississippi River supports a wide range of aquatic species and provides critical habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality in the river and the Gulf of Mexico.
