What is the purpose of "drainage systems" in construction?

To enhance aesthetic appeal of structures

To prevent flooding and erosion by directing water

The purpose of drainage systems in construction is fundamentally to prevent flooding and erosion by directing water effectively. These systems are designed to collect excess rainwater or groundwater and channel it away from buildings and other areas where water can accumulate. This is crucial for maintaining the integrity of structures, as standing water can lead to significant damage over time, including structural weakening, mold growth, and landscape erosion.

In addition, well-designed drainage systems help to mitigate potential flooding by ensuring that water flows to designated areas, such as storm drains or retention ponds, rather than pooling around foundations or roads. This proactive approach to water management protects not only the immediate environment but also contributes to the overall safety and usability of the construction site.
