The Water Tower supplies water to the citizens of Beach City.
The water tower has at least seven long towering support beams holding up the large round container. There is a small, fenced walkway around the circumference of the tower, as well as a ladder to access it. The side of the water tower has "Beach City" written in large letters. There are waves behind the letters, representing the ocean.
The Water Tower was first seen in detail in the episode "Fusion Cuisine" when Steven and Connie bring their families there for dinner, though it is seen in the opening theme, and many episodes as well.
