This $60 million NYCDDC project featured the installation of over 5000 ft of 48" welded steel water main complete with butterfly valves and regulators housed in concrete reinforced chambers. At one location the 48" water main was installed inside a 72" casing pipe that was jacked beneath an existing major box sewer. Micro tunneling of the 72" casing pipe was necessary at a second location which went beneath an elevated railroad owned by the LIRR. Other work included new 8", 12", and 20" distribution main, the replacement/re-routing of existing sanitary and storm sewers adjacent to the trunk main, new curb and sidewalk, concrete base and asphalt paving, street lighting and signal work.
