Wastewater Treatment Facility
DGR worked jointly with the City of Sanborn, Iowa and a large industrial user to evaluate multiple treatment alternatives. Ultimately, the selection of the MBBR was chosen based on cost, operational flexibility and most importantly, limited land availability. Due to the large fluctuations in the industrial loading, a fixed film treatment technology was selected in lieu of activated sludge. Construction of the project started in the beginning of 2019 and was completed in Spring 2020.
