| dc.description.abstract | The main objective of this research is identifying rainwater harvesting as alternative water supply sources in Siyadebirna wayu woreda to solve shortage of water during critical dry seasons. The research is carried out based on case-study of Ejersa kubeti kebeles (Zinjero wuha, Kubeti, Gotet dega and Kebet amba sub-kebeles), from November 2018 to May 2019. The site has about 316 individual compounds which areas 1000m with an average roof area of 62m 2 2 and 93.6% of the study area have suitable roof distribution for rainwater harvesting system. A descriptive quantitative study was carried out in order to achieve the objectives of the study. A daily rainfall data, catchment characteristics, roof material, family size, water consumption and water demand data were collected from primary and secondary sources. The community perspective and practice about rainwater harvesting was assessed. The collected data was analyzed using different tools including samsamwater RWH model, Google earth, GIS, MS Excel spread sheets. The average annual rainfall of the study area is 961.12mm. The water consumption data of the specific sub-kebeles which included in the case study collected from the community through questionnaires and from local water committee. The average water consumption of the specific study area is 143 liter per compound per day. The results from minimum rainfall depth can fulfill the amount of additional water required for five months critical dry season of the study area (33m 3 , 15,360m³ from Micro/Macro). In addition to the rooftop rainwater harvesting the courtyard rainwater harvesting can applicable as combined with roof. In other ways, the possibility large amount of water collection is high. The storage tank can be under ground and covered with geomembraine for protection of water loss through infiltration. The storage tank also constructed with other materials depends on the community capacity. from rooftop, 63m³ from Courtyard with area 150m 2 The amount of water collected from this system used as intermittent. RWH can be used to bridge the dry period with the stored water when other sources are dry. Rainwater harvesting has significant advantages for the study area including health, time saving, energy saving as well as income generation. | en_US |
