Abstract
Surface and ground water sources are the main water sources in Tanzania. In this study Comparison between water potential and water demand up to 2035 for Tanzania water Basins will be presented. The data for Surface water potential, Ground water potential and water demand for all nine major water basins in Tanzania for 2015, 2025 and 2035 were corrected. The Water demand considered were Rural and Urban Water demand, Irrigation, Livestock and Industrial water demand, Mining, Hydropower generation and Environmental Water Requirements. The total water potential (Surface and Ground Water) was calculated, thereafter the percentage of total water demand to total water potential was estimated for 2015, 2025 and 2035. In 2015 the percentage of total water demand to total water potential was 48.83 %, in 2025 is expected to be 56.24 % and in 2035 is expected to be 58.4 %, this implies that the country will face a water stress situation in coming years. The water potential is expected to increase by 0.92% from 2015 to 2025 and 0.071% from 2025 to 2035; this implies that the water potential is diminishing however there is slightly increase of surface water potential.
