A common method used in order to KillItWithWater. See that water tower on top of the building? Well, it turns out these are - ahahaha - filled with water. Knock down the water tower, and a huge torrent of the stuff will come crashing down below. It will displace and pummel any living thing beneath it, and extinguish fire extremely quickly. In a fantastic setting, water-weak creatures will often be wiped out by it. [[MST3KMantra Try not to think too hard]] about why a water-weak opponent would choose to fight anywhere near a water tower.

Not to be confused with ''Literature/WatershipDown''.

[[folder: Comic Books ]]

* Nite-Owl and Silk Spectre take advantage of one of these to temporarily subdue a fire in ''Comicbook/{{Watchmen}}''. It keeps going, but the water clears enough of a path for them to rescue the apartment tenants.
* ''Series/BuffyTheVampireSlayer'' tie-in comic ''Viva Las Buffy'' Buffy is combating vampires on a rooftop. Realizing she's outnumbered, she tosses a conveniently nearby priest into the rooftop water tower and tells him to bless the water. He does so, and Buffy knocks down the tower so the vampires disintegrate from exposure to the now holy water.
* Occurs in the first issue of ''Comicbook/UntoldTalesOfSpiderMan'', where an inexperienced Spidey fights The Scorcher (an armored arsonist) in a warehouse.
* In Detective Comics #825, "Return of Doctor Phosphorus", Franchise/{{Batman}} tries to stop Doctor Phosphorus - a PlayingWithFire villain - using this trope, but it barely slows Phosphorus down.

[[folder: Literature ]]

* One of these is destroyed in an assault on a Japanese-held Australian town, killing a spotter team on it, in AlternateHistory novel ''Designated Targets''.
* In Creator/GKChesterton's ''The Napoleon of Notting Hill'', threatening this is how Wayne finally gets his enemies to surrender. Indeed, [[WordOfGod Chesterton]] described the use of the Waterworks as a weapon as part of the original inspiration.
-->''"In the event of your not doing so, the Lord High Provost of Notting Hill desires to announce that he has just captured the Waterworks Tower, just above you, on Campden Hill, and that within ten minutes from now, that is, on the reception through me of your refusal, he will open the great reservoir and flood the whole valley where you stand in thirty feet of water. God save King Auberon!"\\
Buck had dropped his glass and sent a great splash of wine over the road.\\
"But--but--" he said; and then by a last and splendid effort of his great sanity, looked the facts in the face.\\
"We must surrender," he said. "You could do nothing against fifty thousand tons of water coming down a steep hill, ten minutes hence. We must surrender. Our four thousand men might as well be four. Vicisti Galilaee! Perkins, you may as well get me another glass of wine."''

[[folder: Video Games ]]

* ''SuikodenV'' has Lucretia flooding an entire castle in order to kill the enemy mooks inside.
* In ''BaldursGate'' the cloakwood Mine was abandoned when the miners dug into a riverbed. Years later the [[CorruptCorporateExecutive Iron Throne]] somehow got the hole sealed and the water pumped out, to resume the mining with illegal slaves. After killing the local leader in charge of the mine, you take his key to the seal and then you can figure out the rest...
* In the first fight against Doppelganger in ''MaximumCarnage'', it's possible to instantly defeat him by throwing a nearby water tower at him.
* NeedForSpeed Most Wanted and Carbon used these as pursuit breakers. Drive through the supports and the tower falls on the pursuing police cars.
* In ''VideoGame/TheMatrixPathOfNeo'' during the 'Rooftop Rescue' Mission you can blow up or shoot out the top part of a water tower so that the spilling water slow's down an Agent.

[[folder: Western Animation ]]

* This is the method by which Splinter first defeats the Shredder in the [[WesternAnimation/TeenageMutantNinjaTurtles2003 second cartoon]]; not only does the water throw him from the rooftop, the tower itself then lands on him. Ouch.
* Variant in the ''WesternAnimation/BatmanTheAnimatedSeries'' "See No Evil": when Batman is fighting an invisible opponent under a water tower, he throws a Batarang into the tower's underside, causing water to leak onto his foe and make him visible. (The man is still taken out by Batman's martial arts.)
