Step inside any oil refinery and you’ll notice two things almost immediately — steel everywhere, and water moving constantly through pipes you can’t fully trace with your eyes. Most people associate refineries with crude oil, distillation columns, and flare stacks. But water is just as critical to operations as the feedstock itself. It cools, cleans, transports, separates, suppresses emissions, and eventually carries contaminants that must be removed before discharge or reuse. Managing that water isn’t a side task. It’s central to running a refinery responsibly and profitably.
