Been on my own since I was eight. I'm a fully independent man. Got my own place. Go to night classes. The whole shebang.

Sheng Kawolski is a young boy who is in charge of the water purifier in Diamond City in 2287.


Despite his age, Sheng throws his weight around with any adults he encounters, even calling the player character a "jackass" to their face if they refuse to buy the purified water which he peddles.[1]

During the day Sheng is in charge of Diamond City's water purifying system. At night he goes to the schoolhouse and sits at a desk to take night classes.[2]

This character is a merchant. Sells: Purified water


Pool Cleaning: The player character can ask Sheng for work, whereupon Sheng will give the job of clearing the water around him of any debris that could clog the water filters. Among the miscellaneous junk the player character must find is a human skull. When the job is complete, the player character can confront Sheng about this, to which Sheng will casually reply that he may have sent someone else to do the same job before the player character and that perhaps that person found a live grenade.[3]

Effects of player character's actions

He will replace Travis Miles as the DJ of Diamond City Radio should Travis be killed during the Confidence Man quest.[4]

Other interactions

Upon first approaching Sheng, the Sole Survivor will find him arguing with one of the Diamond City guards about the purity of the water he is in charge of keeping clean.[5]

Behind the scenes

Sheng was voiced by one of Emil Pagliarulo's sons, though he is not credited for the role.[Non-canon 1]


  1. The Sole Survivor: "Not interested."
    Sheng Kawolski: "Your loss, jackass..."
    (Sheng Kawolski's dialogue)
  2. Sheng Kawolski: "That's right. I take night classes."
    (Sheng Kawolski's dialogue)
  3. The Sole Survivor: "Sheng? Why was there a skull in the water?"
    Sheng Kawolski: "Eh, so maybe you weren't the first person I asked. Maybe the last guy found an unstable hand grenade."
    (Sheng Kawolski's dialogue)
  4. Sheng Kawolski: "Hey, so... uhhh... that Travis guy is dead. This is Sheng Kawolski... uhh... seller of fine water products... and I guess I'll play the music from now on."
    (Sheng Kawolski's dialogue)
  5. Diamond City security officer: "Sheng, what have I told you about keeping the lake clean? Don't make me shut down this little stand of yours."
    Sheng Kawolski: "Every drop of water comes out of that filter 100% pure. Why's a legitimate business man like myself always gotta be hassled by city regulation, huh?"
    Diamond City security officer: "It's a health hazard, Sheng."
    Sheng Kawolski: "It's a PROFIT hazard, is what I say. I manage the water. And I'll do it without your interference, thank you very much."
    (Diamond City security officer and Sheng Kawolski's dialogue)
  6. Nat Wright: "You're never going to believe what happened! Sheng Kawolski tried to kiss me."
    Piper Wright: "No! What'd you do?"
    Nat Wright: "What'd I do? I knocked him on his ass. Now I've got detention."
    Piper Wright: "Oh, Natalie. Never change. And you're super grounded. Now go."
    Nat Wright: "Man..."
    (Piper Wright and Nat Wright's dialogue)
