When is mechanical drainage typically utilized?

Mechanical drainage is typically utilized when gravity alone cannot effectively facilitate drainage. This situation often arises in areas where the natural topography does not allow for gravity drainage, such as in regions with flat landscapes or where soil conditions limit drainage capacity. In these scenarios, mechanical systems, such as pumps or suction devices, are needed to actively remove water or excess moisture from the area.

For instance, in basements or large construction sites that remain below the water table, relying solely on gravity would lead to water accumulation, which could damage structures and hinder construction processes. Therefore, mechanical drainage provides a practical solution to ensure effective water management in challenging environments.
