Treatment

Fix broken pipes around Megaton is a minor Fallout 3 quest. When you ask "What needs to be done around here?", Walter refers to broken pipes around Megaton. He asks you to fix them. When asked why he can't fix them, he says he hasn't got the time.

The pipes require a repair skill of 30 or better to fix.

The pipes that have to be fixed are leaking water from them. The locations are as follows:

1. On top of the Children of Atom. Reached easily by jumping down from the right corner of the fence by Craterside Supply. 2. On the hill where you enter. Right by the staircase to get to your Megaton house. 3. Hill opposite of where you enter Megaton that leads to the Common House.

After the pipes are fixed, Walter offers to buy Scrap Metal from you to maintain them. He will give you 10 bottlecaps per Scrap Metal; if you decline payment, you will receive positive Karma (20). You also get a 5 experience point reward per Scrap Metal you give Walter. The amount of experience points gained can be very high if you contribute many Scrap Metals at once while you're well rested, especially if you have the Swift Learner perk.

If your starting intelligence is at least 5, a simple way of completing this is to take Mentats, then equip the Vault 101 Utility Jumpsuit. Doing this will give you the 30 repair skill required to fix the leaking pipes.

Bugs
This quest can become glitched and become either impossible to complete or, in some cases, to even start it. It has been found that the quest-giver, Walter, can fall to his death or wander away through gaps in world geometry. Furthermore it is possible for him to just disapear from Megaton (confirmed on the Xbox360 version). On the PC version, you can recover him by using console commands described in this guide. His reference ID is 3b59.
