Suck in ocean water from one area, blow it out in another. This plant sucks water from the Laguna Madre (the body of water between the Texas coast and Padre Island) then spills the water into the Oso Bay, which is in turn connected to the Corpus Christi bay. This plant is a natural-gas fired plant, but evidently had coal in mind with the docks...cooling water and fuel via the same route.
