What Is a Drainage Channel?
Drainage channels, also known as drainage systems, are trenches or pipelines installed underground to manage the flow of rainwater and wastewater. They are essential in both urban and rural settings, operating on the principle of using gravity to guide water along a slope toward drainage facilities.
In urban areas, drainage channels are found in roads, parks, and residential and commercial areas, while in rural regions, they are essential for agricultural land, roads, and villages. In industrial zones, they serve factories, roads, and ports. There are two primary types of drainage channels: open ditches (gutters), which are surface-level, and closed conduits (underground pipes).
Their key functions include efficient removal of water, prevention of water-related disasters, and improvement of sanitation. To ensure effective operation, these channels must be properly designed with the correct slope and undergo regular inspection and cleaning. This is vital for preventing water-related disasters and maintaining sanitary conditions.
