Water processing plant

The water processing plant is found in Megaton; to reach it take a right after you enter Megaton, it's directly upstairs from Craterside Supply. It is occupied by Walter in the morning, and Leo Stahl at night.

Layout
Walter is usually taking a smoke break outside or is inside tinkering with the various machines inside the plant. Speak to him, and you can begin the unmarked quests Treatment and Walter's Scrap Metal. In the back room is Leo Stahl's desk, and you can speak with him about his drug problem or break open the desk where he hides his chems.

Bugs

 * Walter still describes problems with a possible water shortage and/or contamination even after Holy Water (Broken Steel add-on) is completed.
 * When the pointer is aimed at an object or person in the plant then moved off that object, the cursor will flicker and show the drink option for a split second, and timed correctly you can drink from the object or non-player character and gain HP and a few rads but note the "drink" text is red and doing so is considered a crime.
 * In case Walter is missing see his article for solutions.
