Water tanks are large containers designed to store water for various uses, such as drinking, irrigation, or firefighting. They can be made from different materials like plastic, metal, or concrete, and come in various shapes and sizes. Water tanks help ensure a steady supply of water, especially in areas where access to clean water is limited or during dry seasons. These tanks can be found in homes, farms, and industries, serving essential roles in daily life. For instance, a rainwater harvesting system collects rainwater in a tank, providing an eco-friendly water source. Proper maintenance of water tanks is crucial to prevent contamination and ensure safe water storage.
