Malta Bend WWTP - Secondary Treatment Plant in Saline County, Missouri

Malta Bend WWTP is a municipal wastewater treatment facility located in Saline County, Missouri, United States. The plant serves a small population of 249 residents, reflecting its role in a rural community. Its location near Robertson Lake places it within the Missouri River watershed, which ultimately drains into the Mississippi River. The plant provides secondary treatment, a standard level required by the US Clean Water Act for facilities of this scale. With a designed capacity of 189.27 cubic meters per day and a current discharge volume of 94.64 cubic meters per day, the plant operates at about half its capacity. As a US facility, it operates under an EPA NPDES permit issued by the Missouri Department of Natural Resources, ensuring compliance with federal water quality standards. The treated effluent from Malta Bend WWTP is discharged into local waterways that feed into the Missouri River system. This river system supports diverse aquatic life and provides habitat for migratory birds. The plant's secondary treatment process helps protect downstream water quality by reducing organic pollutants and suspended solids before discharge.

The plant discharges into the Missouri River watershed, which flows into the Mississippi River and ultimately the Gulf of Mexico. The receiving waters support a variety of fish species and provide critical habitat for migratory waterfowl along the Central Flyway. Secondary treatment helps maintain the ecological health of these downstream environments by reducing nutrient loads and preventing oxygen depletion.
