Water sources are essential for life and come in many forms. Wells are a common source of water, consisting of a hole dug into the ground that is filled with water from an underground aquifer. SPIGOTS are pipes or taps that allow water to be released from a reservoir or tank. Founts are similar to SPIGOTS, but they are usually smaller and used to fill containers with water. Fountains are decorative structures that feature a continuous flow of water, often used as a decorative feature in parks and gardens.
