Rainwater Potential

Uganda has an average rainfall of 1200mm per year with a minimum of 500mm in the semi-arid north-eastern region and a maximum of over 2300mm in lake Victoria (figure 1). Roughly, the southern half of the country receives bimodal rainfall with the first rains falling in March - May and the second rains falling in September - November; the Northern half of the country receives unimodal rainfall between April and October/November with a marked decrease in June and July. Generally the country can be divided into five main climatic zones [Rugumayo, 1995] i.e.:

  • The lake Victoria Basin and Central Region with annual rainfall ranging form 1100 - 2000mm, the first rains being heavier. 
  • West and Southwest Region with annual rainfall ranging from 800 - 1600mm annually, the second rains being the heavier. The area is generally semi-arid to moist humid except for the Northwest and the Southwest parts having the heaviest rain. 
  • Northwest and North-central Region with annual rainfall ranging from 1200 - 1600mm. 
  • North - East Region is increasingly semi-arid to arid in the eastern part with the annual rainfall varying between 600 - 1500mm, the rains fall in April - October. 
  • East and Central Region is the transitional zone between bimodal and unimodal rainfall patterns with high rainfall variability between July and November. Rainfall varies from 1100 - 1600mm.

Uganda therefore receives on average substantial and well-distributed rainfall annually and the potential for rainwater harvesting as a source of freshwater supply for domestic and productive use is quite high.
