Waterworks (水道局 Waterworks?) is the water purification and distribution center for DenTech City. During MegaMan Battle Network, the WWW takes over the water control systems and Den City's water supply is completely shut down (and all beverages from vending machines and stores were suspiciously all bought). Lan and MegaMan head to Waterworks where they make their complaint and soon meet their series rivals Chaud and ProtoMan.
