The answer to 'how does drainage system work' is a well-designed drainage system helps remove excess water from your property to prevent flooding, erosion, and other water-related issues. Drainage systems typically include a network of pipes, channels, and other structures that collect and divert water away from your home and landscaping.
The main components of a drainage system include gutters and downspouts that collect water from your roof, underground pipes that carry water away from the foundation, and surface drainage features like swales, French drains, and dry wells that move water off your property. These elements work together to ensure water is properly channeled and doesn't accumulate in unwanted areas.
