Rural Water Projects in Tanzania: Technical, Social, and Administrative Issues. Evaluation Special Study No. 3

摘要

For this evaluation of A.I.D.'s rural water projects in Tanzania, a survey was conducted of 20 Tanzanian villages whose completed water systems used the four major technologies available for dry, wet, and mixed regions. Three major results from this survey are presented in this report. It was found that of the types of water systems surveyed, handpumps represented the most appropriate technology due to their greater reliability and lower capital and operating costs. Shallow wells were also labor-intensive and the use of local construction and maintenance materials increased employment.
