Irrigation, Drainage and Flood Control

The firm’s specialized services in irrigation cover complete range of services from project identification to feasibility study, project preparation, detailed design, construction supervision, project management, operation and maintenance of the small to large scale irrigation projects developed based on concepts of ‘agency’, ‘joint’ and ‘participatory’ management. The services cover both surface and groundwater irrigation schemes.

The feasibility studies are carried out for new irrigation projects as well as those requiring upgrading/improvement, rehabilitation and maintenance. Upgrading/improvement may include essential structural improvement (ESI) for spot improvement to upgrading of system with additional infrastructures.

The planning, design and supervision of construction of drainage, flood protection and river training works requires the coordination of a wide variety of disciplinary activities.
