Drainage systems play a crucial role in civil engineering primarily by collecting and managing excess water. This is essential for preventing flooding and water accumulation on roads, buildings, and surrounding areas. Properly designed drainage systems channel rainwater and runoff away from critical infrastructures, thus protecting them from water damage and ensuring that sites remain safe and usable during and after storm events.

By effectively managing water flow, drainage systems help maintain soil stability, prevent erosion, and reduce the risk of waterlogging in agricultural and developed lands. They are particularly important in urban areas, where impervious surfaces can lead to increased runoff, making it imperative to implement systems that ensure water does not accumulate and disrupt the functionality of both the landscape and infrastructure.

While drainage systems are not primarily designed for recreational spaces or to enhance aesthetic values, they can indirectly contribute to these aspects. Well-planned drainage may support landscape designs that incorporate water features, but the main objective remains focused on managing water effectively. Additionally, while structural integrity is essential, drainage specifically addresses issues related to water control rather than directly supporting the structure itself.
