Drainage is the natural or artificial system of removing water or other liquids from an area, typically via channels, pipes, or other conduits. It refers to the process of eliminating or controlling excess moisture, surface water, or wastewater that accumulates in regions such as land, buildings, or infrastructure.
In its natural form, drainage takes place through natural features like rivers, streams, or natural slopes and gradients. These channels allow water to flow away from a higher to a lower point, ultimately reaching larger bodies of water like lakes, seas, or oceans. Artificial drainage systems, on the other hand, are man-made structures designed to redirect or collect water. Examples of artificial drainage systems include gutters, sewers, culverts, ditches, and subsurface drainage systems.
Drainage is an essential aspect of land and urban planning, agriculture, and civil engineering as it prevents flooding, reduces soil erosion, and protects infrastructure. It helps to maintain healthy soil conditions by regulating the water table level and preventing waterlogging.
In a medical context, drainage refers to the natural or assisted removal of fluids or pus from an infected or wounded area. This process promotes healing by reducing pressure and preventing the accumulation of harmful substances, ultimately facilitating the body's defense mechanisms.
Overall, drainage is a vital process that ensures the effective management of water, promoting safety, health, and overall functionality in various natural and man-made environments.
