SHOWER IRRIGATION TECHNOLOGY ‘A WATER USE EFFICIENCY MANAGEMENT AND FOOD SECURITY PRESENTATION ’ By INVENTOR - MR ISAACK MUNYIRI & ENG. J.KAMAU – KIRDI. Irrigation Made Easy. GROW MORE CROPS PER DROP

WHAT IS SHOWER IRRIGATION? It is a new overhead irrigation concept with the following attributes:- a ) It is a water rationing machine with high water distribution uniformity. b ) It is a mobile system that is highly versatile and maneuverable in the crop field. c ) It uses less fossil fuels making it a “climate smart irrigation system” . d ) It is a closed system vis a vis open furrow system. This reduces water spillage, seepage and evaporation . e ) It is a Low pressure system vis a vis high pressure sprinklers. It uses small portable water pumps of 5 Hp f ) It is the mechanized version of Spot / Bucket crop watering method used by subsistence farmers. It irrigates large tracts of land within a short period of time. 3.
PROFESSIONAL SUPPORT 1. THROUGH COLLABORATION, THE TECHNOLOGY WAS DESIGNED, ENGINEERED & DEVELOPED AT KIRDI. 2. IT WAS TESTED AND EVALUATED BY THE IRRIGATION AND DRAINAGE DEPARTMENT AT KARI. A REPORT WAS PRODUCED TO THAT EFFECT. Irrigation Made Easy. GROW MORE CROPS PER DROP 4.
WATER SAVING VS WATER GUZLER TECHNOLOGIES -1 HA (2.5 Acres) in a 10 Day Irrigation Cycle. 566,660 Lts 171,250 Lts 562,750 Lts NB According to KARI the water use efficiency ratio is 1.0;3.2;3.3 (Shower ; Sprinkler ; Furrow) 5.
COST OF FUEL/ ENERGY FOR PUMPING WATER IN 2 Ha (5 acres) FOR 1 YEAR (360 days) Technology N:B The Shower uses 1,800 liters of petrol per year to irrigate 2 Ha (5 Acres). This is at a cost Ksh 100 per liter or Ksh 180,000 per year (360 days). Applying the KARI fuel/energy use efficiency ratio of, 1.0 : 3.7 : 3.9 for (Shower : Sprinkler : Furrow) the Furrow used 6,600 liters at a cost of Ksh 660,000, while the Sprinklers used 7,020 liters at a cost of Ksh 702,000. On average the shower saved Kes 500,000 in fuel costs. 6.

OBJECTIVE – VALUE ADDITION TO WATER THROUGH TECHNOLOGY TRANSFER & DISSEMINATION OF SKILLS WATER IS A BASIC RAW MATERIAL IN CROP PRODUCTION. LIKE ANY OTHER RAW MATERIAL IT NEEDS TO BE PROCESSED TO DETERMINE ITS VALUE ADDITION. THIS IS BY REDUCING WATER SPILLAGE, SEEPAGE AND EVAPORATION . LEVEL OF VALUE ADDITION IS DETERMINED BY TYPE OF WATER APPLICATION TECHNOLOGY APPLIED. THE SHOWER IS A CLIMATE SMART IRRIGATION SYSTEM. THE OBJECTIVE IS TO ADD VALUE THROUGH TECHNOLOGY TRANSFER AND DISEMINATION OF SHOWER IRRIGATION SKILLS FOR FARMERS TO “GROW – MORE – CROPS – PER - DROP. ” 13.
THE PINEAPLE SHOWER IRRIGATOR The motorized irrigator requires less labour than the manual irrigator 14.
THE BANANA SHOWER IRRIGATIOR 15.
THE SUGAR CANE SHOWER IRRIGATOR The motorized irrigator is also ideal for irrigating tall fruit trees 16 13.
THE COFFEE SHOWER IRRIGATOR 17.
THE HAY / FODDER SHOWER IRRIGATOR Dairy farmers can benefit from technology through hay & fodder production 18.
IMPACT CREATED BY SHOWER TECHNOLOGY 1. BY RE-DESIGNING AND CONVERTING ALL FURROW / SPRINKLER DRIVEN IRRIGATION SCHEMES IN THE COUNTRY TO BEING SHOWER DRIVEN , THE TOTAL AMOUNT OF WATER CURRENTLY USED WOULD BE ENOUGH TO INCREASE THE CURRENT IRRIGATED ACRERAGE OF 250,000 HA TO OVER 800,000 HA WITHOUT INCREASE IN WATER SUPPLY. THE GOVERNMENT WOULD ALSO BENEFIT FROM LOW COST OF DEVELOPING IRRIGATION INFRASTRUCTURE. FOR EXAMPLE WATER USED AT BURA IRRIGATION SCHEME IS ENOUGH TO INCREASE IRRIGATED ACREAGE BY 10,000 HA FROM THE CURRENT 5,000 HA TO 15,000 HA. USING SHOWER SYSTEM 2. FARMERS WOULD ALSO BENEFIT AND REDUCE THEIR COST OF FOOD PRODUCTION. THIS IS ESPECIALLY IN REDUCTION OF FUEL COST FOR PUMPING WATER. REDUCTION OF COSTS LOWERS FOOD PRICES TO THE CONSUMER. 3. THE SHOWER IS A CLIMATE SMART IRRIGATION SYSTEM . LESS USE OF FOSSIL FUELS FOR PUMPING WATER MEANS LESS CARBON EMMISSIONS. 19.

CONCLUSION WATER MANAGEMENT IN IRRIGATION SCHEMES Furrow driven/designed irrigation schemes should be re-designed and converted to SHOWER technology. This will reduce water use and irrigation infrastructure development costs , saving the government billions of shillings. Irrigation Made Easy. GROW MORE CROPS PER DROP 21.
