Planning levels and types of maintenance
Short answer
Irrigation project planning proceeds from national master plan and basin studies through project feasibility and design to operational cropping plans. Maintenance includes routine annual desilting/gate lubrication, periodic relining/re-sectioning, emergency breach repairs, preventive inspections, and major rehabilitation.
Explain different levels of planning in irrigation projects, also explain different types of maintenance in irrigation projects.
Levels of planning
- National (master) planning: long-term national or river-basin plan sets policy, priorities, water allocation among sectors and a pipeline of projects (e.g. Irrigation Master Plan).
- Regional/basin planning: water resources of a river basin are studied; potential projects and inter-basin transfers are identified and ranked.
- Project planning: for a chosen project, the stages are identification, pre-feasibility, feasibility, detailed design and implementation. Technical, economic, social and environmental viability are checked.
- Operational (scheme) planning: seasonal cropping and water-delivery plans and management arrangements for an existing system.
Types of maintenance
- Routine (annual) maintenance: desilting, weed removal, bank repair, gate lubrication; done every year during canal closure.
- Periodic maintenance: repairs done after some years, e.g. relining, replacement of gates, re-sectioning.
- Emergency maintenance: urgent repairs of breaches, landslides, flood damage during operation.
- Preventive maintenance: inspection and minor work to avoid failure.
- Rehabilitation/modernisation: major repair or upgrading of an aged system.
Maintenance needs a budget from irrigation service fee and government, trained staff and active farmer participation.
