Water management in rural domestic households plays an important role in reducing water-related health risks. This study was conducted to examine the relationships between the dependent variable (rural domestic rainwater management) and the independent predictive variables (personal characteristics, tank size, years of water harvest, rainwater harvesting associations, usage instructions including water borne health risk, and tank operation and maintenance) in Uganda. Logistic regression techniques were used on a random sample of 301 respondents to ascertain the influence of predictive variables on rural domestic rainwater management. Analyses of the hypothesised relationship revealed three statistically significant results: years of water harvest, rainwater harvesting associations and usage instructions. Overall, the findings suggest that consideration of usage instructions including waterborne health risks, years of harvest, and local water associations, will improve domestic water management, in combination with progressive measures focused on water quality and quantity. Moreover, medical expenses and time spent in hospitals or health dispensaries will be minimised and saved through utilisation of usage instructions. Experienced harvesting households, those with few years of harvest, and non participants as well in local water associations will easily enrich knowledge of how to minimise contracting water-related diseases.

Given the possibility of waterborne diseases caused by inappropriate rainwater harvesting systems, a survey was conducted in Uganda to assess existing knowledge of both physical and non-physical measures that safeguard harvested rainwater. Households who had received rainwater tanks were assessed on issues related to harvested rainwater quality. The study shows that 84% of respondents were aware of various sources of rainwater contamination, but only 5% were aware that they needed to adjust use of rainwater, depending on whether they cleaned the tank or not. Most of the respondents were not aware that gutter cleaning was necessary to improve water quality. Indeed, as the water from the collection surface is channelled through gutters, a number of measures need to be taken to control the entry of contaminations and subsequent growth of pathogens in the tank, e.g. first flush diverts, installation of filters, chemical use and mesh cleaning. The majority, however, did not take adequate care of the gutters and this impacts on health and social livelihood. Overall, the findings emphasize the need to provide more information to households when installing water harvesting tanks to ensure that the harvested rainwater is of high quality.
