Fix the Necropolis water pump

After talking to the underground ghouls of Necropolis about fixing the pump in exchange for the water chip, the Vault Dweller travelled to another part of the sewers to retieve the parts. Then he went to the water shed, fixed the pump, freed the ghouls prisoner to aquire the location of the door to the vault(which happened to be next door) and took the water chip from the 3rd floor of the vault with out threatening the ghoul population.
