Abstract: ABSTRACT The objective of the study is to diagnoses the technical performance of DRWH schemes implemented by Water Action (an indigenous NGO) in Minjar and Shenkora Woreda, Amhara Regional State. The key selected technical performance evaluation indicators are reservoir capacity, capacity of gutter and down pipes and water quality. The study is conducted on all of the DRWH schemes implemented by water Action in the woreda. The study methodologies employed are literature review, semi-structured interviews, questionnaires, PRA and RRA has been employed to probe more information on the grass root level. The mass curve technique and the SIMTANKA software are also used to establish optimal tank/reservoir/ size. Traditionally excavated pounds, River and deep wells are the major sources of water supply for human being and livestock watering in the woreda. As compared to other water sources traditional excavated ponds are the most reliable sources of water supply though exposed for various contaminants and serves for a few months. Rainwater harvesting is back after having been ignored for decades. For arid and semi-arid regions, DRWH has proven track-record of providing safe water next to the house. The increased interest has been facilitated by a number of external factors among others includes the shift towards more community based approaches, the decrease in the quality and quantity of ground and surface water, the failure of many piped water supply system due to poor O & M, etc. viii The study reveals that, in general, lack of awareness, policy issues, poor system operation or management; lack of regular monitoring and maintenances are among the main technical performance problems on the promotion and implementation of the technology.
