Which drainage type focuses on surface water control in relation to a house structure?

The focus of site drainage is primarily on managing surface water around a house structure. This type of drainage involves strategies and systems designed to collect and redirect rainwater or melted snow that can accumulate on or around a building. Ensuring effective site drainage helps prevent water from pooling near the foundation, which could lead to structural damage, basement flooding, and other water-related issues.

Site drainage typically involves the grading of land, the installation of ditches or swales, and the use of gutters and downspouts to direct water away from the building. By effectively controlling surface water, site drainage is crucial for maintaining a dry and stable environment around the home, promoting both the longevity of the structure and the safety of the residents.

Other types of drainage systems, such as subsurface drainage, foundation drainage, and stormwater drainage, serve different purposes and are specific to different problems associated with water movement and accumulation. While these systems can be integral to overall water management on a property, they do not specifically target the control of surface water in relation to the house structure in the same direct way that site drainage does.
