Water is life for all living things but due to over population and pollution, its stock is going to deplete. Besides, open drainage system in many developing countries is another major source of ground water pollution. Polluted water poses a serious threat to the health of the population. This study is designed to investigate the health risk to residents living near the Manka drain (an open drain) in D.G. Khan, Pakistan. To know the household's (HHs) socio economic status, their awareness about water pollution and their willingness to pay (WTP) for safe drinking water, primary data was collected from the HHs through a well-structured questionnaire. Bivariate Logistic Regression as well as ordinary least square methods was used to know the HH's WTP in the polluted and non-polluted areas. The study demonstrated that the ground water was depleting because of the drain. On the other hand, higher income and educated group of people living in the selected area were found WTP for safe drinking water facility.
