Types Of Drainage
In a Nutshell
- Surface Drainage: Managed above the ground to remove excess water.
- Sub-Surface Drainage: Involves systems beneath the surface for groundwater control.
- Slope Drainage: Utilizes slope to direct water away.
- Downspouts and Gutters: Direct water from roofs to the ground level.
- French Drains: Combines gravel and perforated pipe for water redirection.
- Channel Drains: Used in areas with high water flow, like driveways.

Surface Drainage
Surface drainage systems aim to remove excess water from the surface of the land. This type of drainage includes:
- Runoff Systems: Direct water away from structures and into designated areas.
- Open Ditches: Simple and cost-effective, these ditches collect surface runoff.
For more detailed information, visit Types of Drainage.
Sub-Surface Drainage
Sub-surface drainage systems focus on controlling groundwater levels. These systems consist of:
- Drain Tiles: Perforated pipes installed below ground to collect and redirect water.
- Soakaways: Underground pits filled with gravel or rock to manage excess water.
Refer to this article on Drainage Types for further reading.
Slope Drainage
Slope drainage leverages the natural gradient of the land to direct water flow. Key elements include:
- Graded Slopes: Land is shaped to create a natural downward pathway for water runoff.
- Terracing: Involves creating stepped levels to control the direction and speed of water flow.

Downspouts and Gutters
Gutters and downspouts are critical for managing roof water drainage. Components include:
- Gutters: Channels fixed to the edges of a roof to collect rainwater.
- Downspouts: Vertical pipes that direct water from gutters to the ground level.

French Drains
French drains are used to intercept and redirect groundwater. They feature:
- Gravel-filled Trenches: Facilitate water absorption.
- Perforated Pipes: Installed at the trench base to collect and redirect water.
Find more insights at Home Depot’s guide on French Drains.
Channel Drains
Channel drains are essential in areas with high surface water flow. They include:
- Linear Drains: Installed in pavement or flat surfaces to collect water.
- Grates: Installed atop trenches to allow water flow while blocking debris.
For a thorough understanding, consult Bob Vila’s overview on Channel Drains.
FAQ
What types of drainage systems are best for residential properties?
Residential properties often benefit from a combination of surface and sub-surface drainage systems to manage water effectively.
How is surface drainage different from sub-surface drainage?
Surface drainage deals with water removal at ground level, while sub-surface drainage manages water below the ground through pipes and tiles.
What is the main purpose of a French drain?
French drains are designed to intercept and redirect groundwater and surface water away from a specific area.
Where are channel drains most effectively used?
Channel drains are ideal for high-flow areas like driveways, patios, and walkways to manage heavy runoff efficiently.
How do downspouts and gutters contribute to effective drainage?
Gutters collect rainwater from the roof, which is then directed through downspouts away from the building foundation to prevent water damage.
Is slope drainage efficient for flat terrains?
Slope drainage requires some degree of natural land gradient and may need to be adapted or combined with other drainage types in flat terrains.
Can I install drainage systems myself or should I hire a professional?
While simple surface drainage might be a DIY project, sub-surface drainage systems usually require professional installation to ensure proper function and compliance with local regulations.
