Minor Irrigation Scheme

  • This scheme refers to an irrigation project that utilizes either surface water or groundwater to irrigate a cultivable command area (CCA) of a maximum of 2,000 hectares.
  • Minor irrigation schemes are divided into two primary categories and six sub-categories for classification purposes.
  • The Ground Water (GW) schemes comprise four sub-categories, including:

oDugwells, Shallow tube wells, Medium tube wells &Deep tube wells

  • The Surface Water (SW) schemes fall into two sub-categories, which are:

oSurface flow schemes & Surface lift schemes

  • Minor Irrigation Census: The necessity for conducting a census of Minor Irrigation arose due to the recognition that having a database of these schemes would fulfill the planning, development, and management requirements of these schemes, which play a significant role in agriculture.
  • The inaugural Census of Minor Irrigation schemes was carried out for the reference year 1986-87.
