How does Seaway ensure that the water in the containment zone is free of contamination during Level 3 containment operations?
By maintaining the containment zone, Seaway has the capability of treating the water in the zone (several turnovers, if necessary). This is accomplished by pumping water from the zone through the treatment facility to achieve the desired water quality. As Seaway pumps water out of the containment zone, more water is permitted to flow into the zone to maintain a controlled differential pressure gradient between the inner control zone and the ambient water quality.
