The Aqueduct system has been left unfinished. It's your job to complete it. Click and drag the blue pipes to complete each circuit. You need to make 1 continuous path from the faucet to the drain without any leaks. There are 20 circuits to complete. Press R to restart level Press P to enter a passcode to go to a different level (and see the current level's passcode)
I came across this project shared by a Scratcher in 2015. I believe that @JereTheJuggler has been inactive for many years. While trying to solve some of the levels, the puzzle pieces seemed to get inexplicably stuck and I would have to restart the level and try again. I thought that it may be because it was created pre-Scratch 3.0. I see that some of his projects have been undated, just to "fix" them. I failed in my attempt to decipher the code so I blew it all away and started from Scratch (pun intended). It was a lot of effort to re-invent the wheel (waterworks), but I think that I have come close to the original feel and functionality. ALL costumes are from the original. I could not have created them myself. Many of the levels are the same or close copies. All the code is mine. It looks like the original had a hidden level editor inside but I could not master it. (There are 58 possible puzzle pieces!) I may attempt it in a future version but for now, I don't even know where to start. I am currently building the level codes manually.
