  1. PRESENTATION PAPER ON SMALL SCALE IRRIGATION TECHNIQUESABOUT IRRIGATION INFRASTRUCTURE IN UGANDA BY BYARUHANGA K. GODFREY (COUNTERPART STAFF SIAD PROJECT) 16thApril 2009

  2. CURRENT SITUATION OF IRRIGATION INFRSTRUCTURE • Based on irrigation schemes, most of the few existing irrigation schemes need to be rehabilitated

  3. Components of irrigation infrastructure • Water source ( Water reservoir, lake, river, spring, wells, borehole) • Water conveyance system from source to field (canals or pipes) • Water abstraction (diversion structures, weirs, turnout, vertical check gates and gates) • Facilitating equipment (water pumps, siphons, sprinklers, micro-jets, drippers)

  4. Components of irrigation infrastructure cont. • Energy dissipating structures (drops, cutes, stilling basins and pressure regulating valves • Structures (farm roads, bunds, culverts) • Field • Drainage system

  5. Design procedure • Field survey • Production of topographical map • Irrigation layout plan

  6. JICA DEMO SITE

  7. Small scale gate and turn-out in Bugiri

  8. Irrigation structures in Uganda

  9. Lateral drain joining main drainage canal at Doho irrigation scheme

  10. Shapes of structures

  11. Irrigation structures in Egypt Irrigation canal in Egypt Electric water pump in Egypt Drip lines with drippers

  12. Water reservoir

  13. CHALLENGES • Lack of maintenance culture • Lack of equipment • Erratic weather conditions • Lack of adequate data on rainfall • Funding problem • River bank erosion

  14. ACTION PLAN • Development of water harvesting technologies • Potential sites identification basing on topography and run-off capacity • Soil profiles • Training; Farmers, contractors • Rehabilitation of existing schemes

  15. THANK YOU FOR YOUR ATTENTION
