The West Branch Area Wastewater Treatment Plant, located in West Branch, MI, plays a crucial role in preserving the area and Michigan's surface waters. Completed in 1984, the plant treats a daily flow of .9 MGD with a maximum daily flow of 2.1 MGD, and underwent an upgrade from 2009 to 2012 to accommodate a 5.0 MGD peak. The facility utilizes various processes, including grit removal, primary settling tanks, and trickling filters, to effectively treat domestic sewage collected from the City of West Branch, Ogemaw, and West Branch Townships.
The influent flow is metered and undergoes screening and grit removal before entering the primary settling tanks, where settable solids are removed. The secondary biological treatment process involves two trickling filters, with the option of recycling a portion of the effluent for additional treatment. The plant's operations are carefully controlled to ensure the preservation and restoration of Michigan's valuable water resources.
