- President Avenue Pump Station :
In 2019 NSI installed a cofferdam for a new sewer pump station in Fall River. The 32’x32’x26’ coffer dam used 2 levels of bracing and 35’ PZ22 sheet piles. High groundwater levels and the new configuration required 2 hydraulic beams to promote the installation and beam removal once the station was completed.
