Tank Rehabilitation Programme in Pondicherry

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


Methodoogy

Methodoogy

  • 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


Result

Result

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.

  • Karnataka Community Based Tank

  • Management Project consists of

  • 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).
