Question
Why are dams referred to as multi-purpose projects? Name some important multi-purpose projects of India and its beneficiary states.

Answer

A multi-purpose project is a large scale hydro project often including dams for water retention, canals for irrigation, water processing and pipelines to supply water to cities and power generation. Today, dams are built on various rivers not just for irrigation but for electricity generation, water supply for domestic and industrial uses, flood control, recreation, inland navigation and fish-breeding. Therefore, dams are referred to as multi-purpose projects, for example, the Bhakra Nangal Project.
