- Irrigation
- Water supply
- Hydroelectric power
- Flood control
- Navigation
- Recreation
- Fish and wild life
1. Irrigation
Water stored in a multi purpose project is used to irrigate agricultural crops.
2. Water supply
Especially in urban areas, multi purpose projects are used to supply drinking water or water for industrial purposes.
3. Hydroelectric power
