The findings indicate that 99% of respondents faced problem of water shortage for domestic purposes. The problem of water shortage for domestic use is mainly caused by different factors including garden watering, animal drinking and small industrial activities in the study area, the situation forced the resident to use unsafe water obtained from different sources such as wells, boreholes and natural springs which are not treated. The study further revealed that high cost of drilling bore holes, dumping of waste material near water sources are the major challenges that affect domestic water supply in the study area. In addressing the shortage of domestic water supply in the study area, technical support from government is required in drilling permanent boreholes, reducing cost of water taps connection at household level. The study recommended that the community ought to be provided with skills and knowledge of conserving the available water sources for sustainable use. The community should be given skills on how to harvest and store rain water for domestic purposes.
