What is the primary purpose of an area drain?

The primary purpose of an area drain is to collect surface or stormwater from an open area. These drains are typically installed in outdoor spaces such as parking lots, patios, or around building perimeters to efficiently manage excess water runoff, especially during rain events. By capturing this water, area drains help prevent flooding and pooling, ensuring that water is directed away from structures and allowing for proper drainage of the landscape.

Effective management of stormwater is crucial for maintaining the integrity of the surrounding environment and preventing erosion. Area drains are integral in promoting drainage systems that direct collected water to appropriate disposal areas, such as storm sewers or retention ponds. This not only helps with drainage but also reduces the risk of water damage to property and infrastructure caused by stagnant or overwhelmed surfaces.

Other options might focus on different aspects of plumbing and drainage, but they do not address the specific function of area drains related to surface water collection.
