Caldwell, ID
Dairy Processing Industrial Wastewater Treatment
Supporting leading food production company with improved technology through strategic planning and coordination


IMCO Construction brought improvements to the industrial wastewater treatment plant at Darigold’s Caldwell butter plant to allow discharged waste to remain compliant with environmental requirements. Construction crews demolished an existing storage building and constructed a new dissolved air flotation (DAF) treatment building, a second glass lined steel equalization tank, and pre-engineered metal building. The DAF unit provides chemical and physical treatment of the industrial waste. Conventionally treatable waste is discharged into the sewer system while solids are removed and pumped into trucks that dispose of the solids generated by the development of the adjacent butter facility.
Crews constructed the equalization tank, working their way down using hydraulic jacks to lift the previously built ring above them, while installing the next ring in line. This activity required extensive planning and careful coordination.
