Design a pond in Dodoma to provide water for 140 steers, for irrigation of a 0.2-ha garden, and for a family of four. A suitable site for the dam has a drainage area of 27 ha, and the estimated design peak runoff for a 25-year return period storm is 2.12 m^3/s. Seepage and evaporation losses from the pond are estimated as 57 percent of the storage capacity.
