Keep hearing water sound...

[membrain]

I don't know how to solve this but there is another place where the water sound plays when walking on dry floor. It's up on the platform where you find the ladder which leads you to the sewers the first time. The sound only played after climbing up the ladder a second time. I guess it's because there is water under this platform and the engine can't seperate where you actually walk so just takes the lowest "floor" which is water in my case.
