What is the purpose of a trench drain?

A trench drain serves the primary function of collecting runoff from paved areas, such as driveways, parking lots, or sidewalks. These types of drains are designed to effectively manage surface water by capturing excess water that could otherwise lead to pooling or flooding in those areas. The drain is typically installed along a lower area where water tends to naturally flow and channels it into a system where it can be directed appropriately, either towards a stormwater management facility or a suitable outlet.

By collecting runoff, trench drains help to prevent erosion and sediment transport that can occur when water exceeds the capacity of the surface to absorb it. This system helps maintain the integrity of both the paved area and adjacent landscaping, reducing the risk of water-related issues for both infrastructure and the environment.
