2021年1月4日 · Drainage swales are one of several types of surface drainage systems that slowly filter runoff water as it sinks into the soil while redirected to another location. Swales are typically covered with either grass or another type of vegetation.

Fast-draining soil maximizes drainage efficiency, and perforated pipe underneath the gravel can help with heavy water flow. Small swales can direct gutter water to a dry well, while more substantial ones could run along the base of a hill to divert water around a low-lying house.

A drainage swale is a vegetated channel used in land development designs to divert stormwater runoff usually to a waterway, a storm sewer inlet, or a stormwater management basin. A drainage swale is often also referred to as a ditch or a grass channel and is located in open grass areas or along the side of a road or driveway.

2021年11月30日 · Drainage swales are shallow ditches that blend in with surrounding landscape design, facilitate water management, and encourage natural irrigation. Swales take advantage of natural slopes in the land to direct water downward into all the soil as opposed to letting it pool above ground or waterlog a specific region.

Swale drain systems are lesser known surface systems that are more broad and shallow than trench drains, making them a more subtle option. A swale drain is essentially a ditch that gets covered or lined with either grass or another type of vegetation.
