A drainage system is a network of pipes, channels, and other structures designed to collect and carry away excess water, preventing flooding or water damage. It helps manage rainwater, wastewater, and stormwater by directing it away from buildings, streets, and other areas. The system typically includes drains, gutters, manholes, and outfalls that work together to move water to a safe location, such as a river, lake, or sewer. Proper drainage systems are important for maintaining the safety, cleanliness, and health of an area by controlling water flow and preventing accumulation.
