Forming and Registering Tank Associations

  • General Body constituted with 1 male and 1 female representative from each household in the village.

  • The GB elects an executive committee.

  • Adequate representation to all sections with “weighted voting”.

  • Special emphasis on representation for landless, dalits &women

The Case

Reason for rehabilitation
Reason for Rehabilitation

Tank association trained and guided to evolve action plan for rehabilitation of the tank. Because of exclusive reliance on ground water over the last two decades the tank system was in disuse, the ground water was depleted with saline water ingress, and large areas had no access to groundwater as they were unable to deepen the bore well. The community had to understand that the solution lay not in more ground water but in tank rehabilitation.

The Case


  • Tank association came up with new technological solution - the underground water conduit- for a locale specific problem and the engineers finally consented.

  • New social solutions also involved to give landless benefits from tank rehabilitation - fish culture, and fodder cultivation.

The Case


Programme successful with benefits immediately seen. The tripartite system of government public works department, the tank association and the NGO is the key to success. The NGO plays the role of forming, training and supporting the tank association.

The Case

The village tanks
The Village Tanks

  • Local community resources

  • Indigenous, traditional technology

  • Agricultural lifeline

  • Predominantly in the Deccan Plateau, Eastern India and Chhotanagpur Plateau due to undulating topography.

  • In Orissa alone 3 lakh ha is irrigated by

Tank rehabilitation

  • The World Bank funded

  • Karnataka Community Based Tank

  • Management Project consists of

  • three components:

  • undertaking tank system improvements;

  • 2) establishing an enabling environment for the sustainable, decentralized management of tank systems; and

  • 3) strengthening community-based institutions to assume responsibility for tank system development and management (World Bank, 2002).

Pradan model

  • Trust building

  • Standardisation

  • Integrated Tank Development System

  • Self management
