French Drain
- Purpose: Primarily used for directing water away from areas prone to pooling or flooding, such as foundations, basements, or low-lying lawns.
- How it Works: A trench is dug and filled with gravel, with a perforated pipe placed inside. The pipe collects and directs water away from the area, typically to a storm drain or a dry well.
- Best For: Areas with poor drainage, foundations, basements, and sloped areas.
Surface Drain (Catch Basins and Grates)
- Purpose: Designed to collect surface water that pools on driveways, walkways, patios, or lawns.
- How it Works: A surface drain (catch basin or grate) is installed at the lowest point of a flat area. Water enters through the grate and is funneled into an underground drainage pipe to be directed away from the property.
- Best For: Driveways, parking lots, sidewalks, and flat areas where water tends to collect.
Channel Drain (Trench Drain)
- Purpose: Used to direct water away from patios, driveways, or along the edges of structures like garages or pools.
- How it Works: A long, narrow channel is installed along the surface, with a grate on top. Water flows into the channel and is carried away through the drainage system.
- Best For: Patios, pools, driveways, and pathways.
Catchment Pond or Retention Pond
- Purpose: Used to collect and manage stormwater runoff. These are large, shallow ponds that store water during rain events and release it slowly over time.
- How it Works: A catchment or retention pond holds water temporarily and slowly releases it into nearby drainage systems. These are often used in urban or large commercial developments to manage stormwater.
- Best For: Large commercial properties, industrial areas, or urban developments.
Surface Grading
- Purpose: A simple technique to ensure water flows away from structures like foundations, driveways, or patios.
- How it Works: The land around a building is graded (or sloped) so that water naturally flows away from the structure.
- Best For: Residential lawns and foundations.
Subsurface Drainage
- Purpose: Installed below the surface, subsurface drainage systems are used to remove excess water that accumulates beneath the ground.
- How it Works: A series of perforated pipes are buried beneath the soil in areas prone to waterlogging. Water is collected through the pipe system and directed to a suitable outflow point.
- Best For: Agricultural fields, golf courses, sports fields, and lawns with poor natural drainage.
