One of the environmental challenges is the effect on water availability and water-related diseases accounts for 80 percent of sicknesses in developing countries. Despite this, there has remained increasing research on poverty reduction, with little emphasis on water access particularly in Africa. Using micro-level data from survey conducted by the World Bank and National Bureau of Statistics, covering over 5,000 households and 27,000 household members across the 36 States of Nigeria, the study formulates an econometric model. The results from logistic regression analysis show that the main determinants of households access to water include: age of the household members, the marital status, the sector where the household member works, the type of employment, the number of working hours, access to informal means of financial credit and the income level of the household, among others. Some recommendations on how to boost water access of households are made in the study.
