A water tank is a container designed to store water for various uses, such as drinking, irrigation, or industrial processes. They come in different shapes and sizes, including cylindrical, rectangular, and underground models. Water tanks can be made from materials like plastic, metal, or concrete, depending on their intended purpose and location. Water tanks are essential for maintaining a steady supply of water, especially in areas where access to a reliable water source is limited. They can be connected to a water supply system or filled manually. Proper maintenance is crucial to ensure the water remains clean and safe for use.
