The Terminal 5 Project at the Port of Seattle involves maintenance and update of the terminal 5 berth, as well as utility upgrades adjacent to the terminal. Clear Water is responsible for treating several known contaminants in the groundwater, as well as managing the stormwater. The project required (2) 250 GPM CESF systems, both with Carbon filtration for contaminant removal. One system needed to be upgraded to a 500 GPM flowrate capacity, and Clear Water was able to complete the upgrade in one day.
