  • PRESENTATION PAPER ON SMALL SCALE IRRIGATION TECHNIQUES

    ABOUT IRRIGATION INFRASTRUCTURE IN UGANDA

    BY

    BYARUHANGA K. GODFREY(COUNTERPART STAFF SIAD PROJECT) 16thApril 2009

  • CURRENT SITUATION OF IRRIGATION INFRSTRUCTURE

    Based on irrigation schemes, most of the few existing irrigation schemes need to be rehabilitated

  • 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)

  • Components of irrigation infrastructure cont.Energy dissipating structures (drops, cutes, stilling basins and pressure regulating valvesStructures (farm roads, bunds, culverts)FieldDrainage system

  • Design procedure

    Field survey

    Production of topographical map

    Irrigation layout plan

  • JICA DEMO SITE

  • Small scale gate and turn-out in Bugiri

  • Irrigation structures in Uganda

  • Lateral drain joining main drainage canal at Doho irrigation scheme

  • Shapes of structures

  • Irrigation structures in EgyptIrrigation canal in EgyptElectric water pump in EgyptDrip lines with drippers

  • Water reservoir

  • CHALLENGESLack of maintenance cultureLack of equipmentErratic weather conditionsLack of adequate data on rainfall Funding problemRiver bank erosion

  • ACTION PLANDevelopment of water harvesting technologiesPotential sites identification basing on topography and run-off capacitySoil profilesTraining; Farmers, contractorsRehabilitation of existing schemes

  • THANK YOU FOR YOUR ATTENTION
