There are several ways to save water, such as taking shorter showers and not leaving the tap running unnecessarily. Water can also be reused, like collecting rainwater in tanks. Some countries waste more water than others due to large swimming pools, gardening needs, and long baths. People in countries without reliable access to water survive by drinking whatever water is available, even if contaminated, and walking long distances like children in Africa who spend hours each day getting water for their families.
