Puritan-Fenkell Facility
CSO & RTBLocated in Eliza Howell Park, the Puritan-Fenkell CSO retention treatment basin (RTB) is the third Rouge River CSO RTB. Despite its small size, the Puritan-Fenkell proved that 20 minutes of detention time for settling and disinfection of the 1-year, 1-hour storm event peak flow is sufficient to meet protection of public health standards. The 2.8-million-gallon facility became operational in August 1999 and eliminated two untreated CSO outfalls.
