Drainage pipes are essential components of a drainage system, designed to carry excess water away from areas like buildings, roads, and agricultural fields. They help prevent flooding and water accumulation by directing water to appropriate outlets, such as stormwater drains or sewage systems. These pipes are typically made from materials like PVC, HDPE, or concrete, and come in various sizes and shapes to suit different applications. Proper installation and maintenance of drainage pipes are crucial to ensure efficient water flow and to avoid blockages that can lead to water damage or environmental issues.
