ЁЯТб Explanation

SAUNI (Saurashtra Narmada Avataran Irrigation) Yojana is a major irrigation and water supply project in Gujarat designed to fill 115 reservoirs in the arid Saurashtra region using surplus water from the Narmada River. It utilizes a vast network of pipelines, canals, and dams to mitigate water scarcity and facilitate agricultural growth.

тЪЩя╕П Working Principle

The project operates on the principle of lift irrigation and gravity-fed distribution. Surplus flood water from the Sardar Sarovar Dam is diverted through a massive pipeline network spanning over 1,100 km, integrated with existing dams and check dams to recharge the local water table and ensure irrigation availability in drought-prone areas.

ЁЯУМ Key Points
  • тЦ╕

    Project aims to fill 115 dams in Saurashtra using Narmada water.

  • тЦ╕

    Eliminates dependency on erratic rainfall patterns in the region.

  • тЦ╕

    Pipeline-based distribution reduces water loss due to evaporation and seepage compared to open canals.

  • тЦ╕

    Crucial for both irrigation and municipal drinking water supply.

тЬЕ Advantages
  • тЦ╕

    Significant reduction in agricultural water stress.

  • тЦ╕

    Recharging of groundwater aquifers through dam filling.

  • тЦ╕

    Minimal land acquisition compared to traditional canal networks.

тЭМ Disadvantages / Limitations
  • тЦ╕

    High initial capital investment for pipeline infrastructure.

  • тЦ╕

    Energy-intensive pumping required for high-elevation areas.

ЁЯЫая╕П Applications / Uses
  • тЦ╕

    Large-scale agricultural irrigation.

  • тЦ╕

    Municipal drinking water provision.

  • тЦ╕

    Industrial water supply.

ЁЯУД Additional Information
  • тЦ╕

    The project is divided into four main 'links' to cover the 11 districts of the Saurashtra region.

  • тЦ╕

    Option B and C are incorrect as North Gujarat is served by different water management frameworks like the Sujalam Sufalam Yojana.
