The Wastewater Treatment Plant (WWTP) came on-line in August of 2012. It operates on a continuous fill Sequencing Batch Reactor (SBR). This replaced the old 1956 trickling filter WWTP. There are 4 SBR basins and each basin provides treatment to its contents. The SBR cycles are react, settle and decant. Each basin treats 5 batches of wastewater per day. The SBR WWTP includes overflow equalization, screening, grit removal, raw wastewater pumping, SBR treatment, UV disinfection, aerobic digestion for the biosolids, a biosolids storage basin and a laboratory/office building.
The WWTP is regulated by the Iowa Department of Natural Resources and the United State Environmental Protection Agency.
