The answer to 'types of drainage system' is that there are several common types of drainage systems used in landscaping, each designed to address specific drainage needs. The most common types include surface drainage, subsurface drainage, and French drains.
Surface drainage systems use swales, ditches, and culverts to channel water away from the property and prevent pooling or flooding. Subsurface drainage systems, such as perforated pipes or tile drains, are buried underground to collect and divert excess groundwater. French drains are a type of subsurface drainage that uses gravel-filled trenches to intercept and redirect water flow.
