French bean (Phaseolus Vulgaris variety Vernondon) was introduced in Kenya to increase the income of small farmers and encourage export of vegetables. At present, there are 4,000 farmers each cultivating an area of 170 m around Lake Victoria where suitable soil and climatic conditions exist, covering a total cropped area of 150 ha during 1982-83. Analysis of rainfall data, variation of soil moisture and infiltration characteristics indicated that: 1) normally the average intensity of rainfall exceeds the rate of infiltration up to 200 minutes, thus allowing runoff to be harvested; and 2) at a probability level of rainfall equal to or greater than 50%, there is moisture stress in all the months except April and May. The conditions for the most economical dimensions of a frustum of a square base pyramid were determined by mathematical analysis. The dimensions for two sides slopes 0 = 45 degrees and 0 = 60 degrees were calculated. The cost of plastic lining varies from Sh300 to Sh600 for a storage volume of 10 to 20 m.
