The City of Flandreau was struggling to meet the South Dakota Department of Environment and Natural Resources’ (SDDENR) discharge permit requirements. The City asked IMEG for assistance to bring the ponds into compliance. The Project included:

• Piping and valves between ponds
• Raising the dike of two ponds by 18-inches
• Adding level monitoring for each pond
• Installing inlet and outlet flow meters and lids
• Erosion control
• Seeding

During design and construction, IMEG collaborated with neighboring farmers to limit obstructions to their operations, and to design outlet valves for wastewater utilization.
