Which of these is NOT a type of drainage system commonly used in construction?

• A. Surface drainage
• B. Subsurface drainage
• C. Interceptor drainage
• D. Overhead drainage

Answer: (D)

Overhead drainage is not recognized as a standard type of drainage system used in construction. The primary types of drainage systems include surface drainage, which collects and redirects water that falls on the land surface; subsurface drainage, which involves systems installed below the ground to manage groundwater levels; and interceptor drainage, designed to intercept and redirect water flows that could create issues, such as erosion or flooding. These systems function to manage water effectively and prevent damage to structures, ensuring the health of the surrounding environment. In contrast, the concept of overhead drainage does not align with typical practices in drainage management, as it is not employed in the same manner as the other recognized systems.
