There are various forms of drainage systems, and each one has a specific purpose in controlling water flow:
- Surface Drainage System – This system drains excess water from the ground surface, often employing channels, ditches, or drains to re-direct water away from points where water can be a cause of damage or flooding.
- Subsurface Drainage System – Intended to treat water that accumulates below the ground surface, the system employs buried pipes or perforated tubing that harvest and transfer groundwater.
- Slope Drainage System – The main application for sloping sites, this system controls runoff and erosion by funneling water downwards and away from sensitive areas.
Downspouts and Gutter Systems – Such systems are generally placed along roofs and assist in channeling rainwater from gutters to the ground, thereby avoiding water from accumulating around the foundation of a building.
