Different Types of Outdoor Drainage Systems

What Are Channel Drains?

Like French drains, channel drains, also called trench drains, consist of a long, narrow trench that collects surface water and directs it to a drainage system. These linear drains are generally installed in hardscaped areas such as driveways, patios, and pool decks. Channel drains include a grated cover usually made from materials such as stainless steel or plastic to capture debris and objects.
One of the significant advantages of channel drains is their ability to handle large volumes of water quickly. They are particularly useful in areas where there is heavy rainfall or frequent flash flooding, as they can prevent water from pooling and causing damage to hardscaping materials or structures. They can also help to prevent slip and fall accidents by keeping walking surfaces dry and free of standing water.

What are Catch Basins?

Catch basins are underground chambers designed to collect water and debris from a drainage system. Inside the basin, there is a sump or pit that traps sediment and debris from the water, preventing it from flowing into the drainage system. The collected water is then directed through a pipe to a discharge point such as a retention pond or a river.
They are typically placed at the lowest point in the yard and connected to a network of pipes that carry the water away from the property. Catch basins are ideal for large areas with heavy rainfall, such as commercial properties and parking lots.

What is Dry Wells?

Dry wells are underground chambers that collect water and allow it to percolate into the ground slowly. They are typically installed in areas with poor soil drainage, such as clay soils. Dry wells can be thought of as a simplified version of the catch basin.
