The Irrigation and Water Resource Management Project (IWRMP) is financed by the World Bank (WB), the Government of Nepal (GON), and the involved Water User Associations (WUAs), and is being executed by Department of Irrigation (DOI). 


Components of IWRMP

A – Rehabilitation and Modernization of Irrigation Infrastructure

B – Irrigation Management Transfer Reform

C – Institutional and Policy Support for Improved Water Management

D – Integrated Crop Water Management


Overall objectives of Component B

  •  To improve irrigation service performance and service delivery to selected irrigation systems in the Terai through the completion and consolidation of Irrigation Management Transfer (IMT) to the relevant Water Users Association (WUAs).
  •  To address problems exhibited in large public irrigation schemes (Agency Managed Irrigation Systems or AMIS) of below capacity performance, poor O&M, low cost recovery, and inadequate maintenance funds.


The original scope of project interventions envisioned working in 9 subsystems, then was reduced to 4 subsystems for the Original Scope, and then later 3 more subsystems were added for Additional Financing as shown in Table E-A:
