What is another term for underground drainage systems?

The term "subsoil drains" specifically refers to drainage systems that are installed underground to manage groundwater and prevent water accumulation in soil that could lead to damage or instability. These systems are crucial in agricultural, residential, and commercial settings, as they help to control excess moisture in the soil, thereby protecting foundations, landscaping, and crops.

Subsoil drains often consist of perforated piping that collects and transports water away from areas where it is not wanted. Their primary function is to lower the water table and direct excess water to designated areas, such as drainage fields or natural water bodies, contributing to effective land management.

In contrast, storm drains typically refer to systems designed to manage surface water runoff during rain events. Surface drains are meant to manage water that accumulates on the surface rather than below ground. Rainwater drains are systems specifically designed for capturing and directing rainwater from roofs and paved surfaces. While these are all essential components of a broader drainage strategy, they do not capture the specific nature of underground drainage systems like subsoil drains do.
