Drainage channels are open or enclosed conduits designed to collect and convey excess surface water, wastewater, or stormwater away from roads, fields, buildings, and other infrastructure. They play a critical role in preventing flooding, reducing erosion, and managing water flow in urban, suburban, and rural areas. Constructed from materials like concrete, metal, or plastic, drainage channels can be natural or man-made and vary in size and design to accommodate different volumes and types of water runoff. Their effective design and maintenance are essential for protecting property and maintaining environmental health.
