Multi-purpose projects are the projects which were constructed after the independence of India to use the water for various purposes. Dams are one of the major multi-purpose projects. The uses of multi-purpose projects are:

1) They provide water for irrigation.

2) Dam water is used for hydroelectric plants to generate electricity.

3) Dam water is also supplied for domestic use.

These multi-purpose projects were also used to stop floods, but they have failed many a times. Bhakra Nangal project is one of the biggest multi-purpose projects in India.
