The Huffman-Putnam Sewer Separation project will contain over 13,000 feet of new storm sewer from 12'' to 72'' in diameter thus separating runoff from portions of Huffman St, Putnam St, Sherman St, Wells St, and 6th St to the St Mary's River via the abandoned 3rd street gravity CSO outfall that will be reused as a new storm outfall. The proposed storm sewer will connect to Hamilton Park to help relieve the detention system. The new storm sewers will pick up inlets/catch basins and parking lots that are currently connected to the combined system which will reduce basement backups and help to minimize CSO overflows at the 3rd Street Pump Station. Green infrastructure such as bio retention and infiltration swales BMPs will be incorporated into the project to aid in water quality for newly separated storm water.
Total improvements, approximately: $6 million
