Which best describes a 'drainage system'?

A drainage system is specifically designed to remove excess water from a designated area, effectively managing water runoff and preventing flooding or water accumulation. This system typically includes a network of pipes, channels, and other components that guide rainwater or wastewater away from structures and into safe disposal areas, such as sewer systems or natural water bodies.

In contrast, a system that supplies water to fixtures refers to plumbing for delivering potable water, while a collection system for wastewater treatment pertains to the process of gathering and treating used water. A network of pipes for delivering hot water specifically focuses on the transportation of heated water for various applications, which does not encompass the broader function of drainage.
