The collection system has nearly 4,000 sewer connections, most of which are residential. There are about 150 commercial connections and around ten industrial connections. The City's existing WWTP was originally constructed in 1978 and has since been upgraded and expanded several times. The WWTP consists of a headworks that includes a bar screen and splitter box, three primary clarifiers to remove settleable solids, and a series of aeration ponds to reduce biological oxygen demand. Treated effluent is disposed via spreading and percolating effluent in disposal fields adjacent to the aeration ponds. Sludge and scum from the primary clarifiers are pumped to an aerobic digester. Digested sludge is sent to sludge drying beds where the moisture evaporates, and the dried sludge is hauled offsite to a landfill. The method of Contractor Selection has not been Determined at this time.
