College of Engineering Unit:
Lakedale Utility District noticed aesthetic issues in the drinking water from the Crestop Well, one of their highest producing wells. Concentrations of iron and manganese leave the water discolored and stain fixtures along with hydrogen sulfide creating an unpleasant odor. A treatment system was requested from the District in order to remove these contaminants below detection to uphold their reputation for clean, high-quality drinking water. The treatment system considers undergoing population growth and supplies water reliably year-round. The treatment plant does not exceed a 2000 sq. ft. footprint, removes iron and manganese below the Secondary Maximum Contaminant Levels (SMCLs), provides an average process flow of 1050 gpm, and requires minimal in-person monitoring and maintenance. After comparing varying treatment alternatives through a cost analysis, the chosen method of treatment for the Crestop Well includes a potassium permanganate oxidation and greensand filtration system followed by chlorine residual disinfection.
