The fountains are self-contained, as the bottom has a plate/reservoir and the water pump will circulate the water. The water pump (which runs through the base of the fountain jar) needs to be connected to a power source.  

There is a small dripping noise but it’s a relatively low sound. Unfortunately, we don’t have any information about the decibels. When the water volume in the bowl is larger, there is less of a sound.

Cleaning once a month should be fine. You can clean it with mild soap and water.
