Overview
Hubbard Lagoon is a secondary wastewater treatment plant serving approximately 845 residents in Hubbard, Iowa. The facility discharges 302.83 megaliters annually and has a designed capacity of 454.25 megaliters.
Hubbard Lagoon is a municipal wastewater treatment facility located in Hubbard, Iowa, serving a small community of approximately 845 people. The plant is situated in Hardin County, within the rural agricultural landscape of the Midwestern United States. The facility provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater plants. With a designed capacity of 454.25 megaliters and an annual discharge volume of 302.83 megaliters, the plant operates below its capacity, indicating room for future growth. Treatment processes typical for lagoon systems in this region involve stabilization ponds that use natural biological processes to treat wastewater. The treated effluent from Hubbard Lagoon ultimately drains into the Iowa River basin, which flows into the Mississippi River and then to the Gulf of Mexico. This downstream connection places the plant within the context of the Mississippi River watershed, where nutrient management is critical to reduce the hypoxic zone in the Gulf. The plant's secondary treatment helps control organic pollutants and nutrients, contributing to regional water quality efforts.
Environmental context
Hubbard Lagoon discharges into local waterways that are part of the Iowa River basin, a tributary of the Mississippi River. The Mississippi River carries treated effluent to the Gulf of Mexico, where nutrient loading contributes to seasonal hypoxia. The plant's secondary treatment reduces biochemical oxygen demand and suspended solids, but nutrient removal is limited, making its discharge relevant to downstream water quality management in the Mississippi River watershed.
