Water storage containers are used to safely store and transport large quantities of water for a variety of purposes. They are usually made of plastic, metal, or concrete and vary in size, shape, and capacity. Water storage containers can be used for emergency water supply storage, such as in case of natural disasters, or for more mundane purposes such as watering a garden. They are designed to be airtight and watertight, and come equipped with lids and covers to protect the water from contamination or evaporation.
