Overhead tank is a water storage container typically positioned above ground level, often on a raised platform or structure, to supply water through gravity flow. These tanks are commonly used in residential, commercial, and industrial settings to ensure a consistent water supply, especially in areas where water pressure is low or unreliable. Overhead tanks are usually made from materials like plastic, concrete, or metal and come in various sizes depending on the required storage capacity. Their elevated position allows for efficient distribution of water to lower floors or areas without the need for additional pumping.
