A new Sculpture Large Wave found under Decor / Misc. Decor, costs 0. Because there is such a shortage of sculptures in the game I decided to clone the Bridgeport sculpture for my game. It doesn't show the water jets, but the water moves. It DOESN'T WORK in the game as it comes out all transparent, it needs to be installed in CAW. You need Late Night and to place the package in both the mods/packages (Sims3 ) directory and in the "The Sims 3 Create a World Tool/ Packages" directory for the item to show in your game. There is an earlier post explaining how to install items in CAW.
