Drains are systems designed to remove excess water or waste from an area. They can be found in homes, streets, and even in nature. For example, in a house, kitchen sinks and bathrooms have drains that carry away used water. Outside, storm drains help prevent flooding by directing rainwater into underground pipes. In addition to their practical use, drains play a crucial role in maintaining cleanliness and hygiene. They help prevent the buildup of stagnant water, which can attract pests like mosquitoes. Properly functioning drains ensure that our living spaces remain safe and comfortable for everyone.
