Description

A municipal water supply organization was constructing a large water treatment facility situated on the outskirts of New York City. Construction crews encountered a leaking bypass pipe at a depth of 400 feet below the surface between two adjacent deep water supply shafts.

Multiurethanes grouting specialists supported decommissioning operations undertaken by a deep dive contractor to fill the defective bypass pipe using cement grout.  In addition, they prepared customized electrical equipment for this underwater grouting project, including a diesel generator and an electrical control panel with variable frequency drives to operate colloidal mixer, agitator tanks, and progressive cavity pumps.
