Pier T Wharf Extension Underground
Griffith Company has been working on storm drain and domestic water improvements for the Port of Long Beach’s Pier T Wharf Extension Project. Griffith Company has recently completed the final storm drain connection to the ocean, including the demolition of an existing 6’ thick concrete Seawall for the installation of a 42” outfall to the harbor. The domestic water improvements consist of a 12” backbone that is connected to the Port of Long Beach backlands water system. The storm drain improvements consist of reinforced concrete pipe, high-density polyethylene pipe and case in place concrete structures.
