Specifications include, but are not limited to: This project is for the cleaning of a 60 inches reinforced concrete pipe from Grace Street to Burt Izard lift station that is from Manhole # 3004002 to Manhole# 3001010 as outlined in the specifications, and dragging or pushing of debris from the Minne Lusa diversion structure to the nearby grit chamber. The length of the pipe to be cleaned is estimated to be 4400 feet. It is anticipated that the first 1000 feet of the sewer line contained large debris due to the failure of the screen system in the Grace Street Diversion Structure and about 20 inches of debris along the rest of the pipe for a total estimation of 700 tons of debris to be removed. The load rough estimate is based on CCTV and Sonar investigation that was performed on sections of the pipe. The manholes depths are approximately 20 to 30 feet and Annual Average Flow approximated to be 10.8 MGD.
