Types of channel drains and their commercial uses

by Natalie Rager

Channel drains, also known as linear drains, are drainage systems that are designed to collect and remove surface water. There are several types of channel drains, including:

  1. Pre-sloped channel drains: These types of drains have a built-in slope that ensures water flows towards the outlet. They are easy to install and provide a cost-effective solution for managing surface water.
  2. Modular channel drains: These drains are made up of precast concrete or plastic sections that can be easily assembled to create a custom drain length. They are ideal for projects where a specific drain length is required.
  3. Slot drains: These types of drains have a narrow slot opening along the top of the channel that collects water. Slot drains are aesthetically pleasing and can be disguised as part of the surrounding landscape.
  4. Trench drains: These drains are similar to pre-sloped channel drains, but they are typically wider and have a larger capacity. Trench drains are often used in areas with high volumes of water, such as industrial sites and car parks.
  5. Stainless steel channel drains: These drains are made from durable stainless steel and are ideal for high-traffic areas. They are easy to clean and maintain, making them a popular choice for commercial and industrial applications.
  6. Plastic channel drains: These drains are lightweight and easy to install. They are an affordable option for residential applications and can be used in areas with light to moderate foot traffic.
  7. Cast iron channel drains: These drains are made from durable cast iron and are ideal for heavy-duty applications. They are resistant to corrosion and can withstand high volumes of traffic.

Channel drain uses in parking lots:

Did you ever observe drainage systems in public parking lots and the mechanism behind it? Channel drains are commonly used in parking lots to manage surface water and prevent flooding. Parking lots are often large, flat surfaces that do not allow water to naturally drain away, and channel drains can provide an effective solution to this problem.

Here are some common uses of channel drains in parking lots:

  1. Collecting surface water: Channel drains are placed along the edges of parking lots and are designed to collect surface water before it can pool and cause flooding.
  2. Preventing water damage: By channelling water away from the parking lot, channel drains can help prevent water damage to surrounding buildings and structures.
  3. Improving safety: Standing water in parking lots can create slippery surfaces that can be hazardous to pedestrians and drivers. Channel drains help to remove the water and improve safety.
  4. Managing stormwater: Parking lots are a major source of stormwater runoff, and channel drains can help manage this runoff by collecting it and directing it to a retention pond or other stormwater management system.
  5. Enhancing aesthetics: Channel drains can be customized to blend in with the surrounding landscape, providing an aesthetically pleasing solution to managing surface water in parking lots.

Regardless, channel drains are an effective and practical solution for managing surface water in parking lots, helping to improve safety and prevent flooding and water damage.
