Walter was born in 2216. He spends his days minding the machines and fixing drainage devices that break. He's increasingly worried about the state of the water and drainage structure, and knows it won't hold much longer - and neither will he. At 61, he's one of the oldest residents. He also has a preference for Enclave Radio, though never actively listens to it, citing it as being "downright patriotic."
During the daytime, Walter can be found in the water processing plant for most of the day, though sometimes he will step outside for some air. During the night hours, he can be seen drinking in Moriarty's Saloon.
Treatment: Walter will ask the Lone Wanderer to fix all the leaking water pipes around Megaton. When finished, he will give you 200 caps and XP.
Walter's Scrap Metal: Upon fixing all the leaking pipes Walter will ask the Lone Wanderer to bring any scrap metal they find, and as reward Walter will give them 10 caps per and XP. If you give scrap metal to Walter without charging him, you will gain karma and earn extra XP.
"Alright... alright... relax. But all you've done is delay the inevitable. Without those parts, the plants gonna croak sooner or later. But what do you care? You just want your money. Here, take it and get out."
