The operation inside the water treatment plant was utterly routine, as easy as strolling through a shopping mall. There were no guards, no security personnel, not even any security equipment. The doors were not even locked. Deadpool carried the Mushroom Living Corpse on his shoulder and marched straight in, heading directly for his destination according to the plant layout.
Water treatment plants around the world followed the same seven-step process for supplying water.
First, after natural water entered the plant, it went into a reaction tank, where purifying agents such as alum or powdered activated carbon were added. Second, if the water's pH was too low or too high, neutralizers were added to keep the pH around 7 to 8.
The third step was sedimentation. After passing through the reaction tank, the purifying agents mixed thoroughly with the source water before flowing into a sedimentation basin, where impurities settled at the bottom. The fourth step came after most impurities had settled: the water flowed into filtration tanks, which generally filtered it through several layers of sand of varying coarseness. Some processes also used activated carbon filtration.
The fifth step used adsorption to remove residues that might have been left behind by the previous steps. The sixth was sterilization, generally through chlorine or ozone. After sterilization, the water entered a clear-water reservoir for storage. The final, seventh step was pressurization by pumps, sending tap water to countless households.
Deadpool's destination was the clear-water reservoir, or rather, a massive underground water storage structure. Such giant underground reservoirs usually had an inspection hatch, and he found it without any trouble.
He set down the zombie from his shoulder, stretched his aching back, and began tearing off the plastic wrap as he spoke.
"Shroom, this is where you prove yourself. Don't disappoint me. If
