This study aims to measure the efficacy of drinking water in terms of the economic impacts and risk of illness involved in using perilous water sources. Socio-economic factors were also considered. A multidisciplinary approach was employed to analyze the data, including the cost of illness (COI), regression technique, and irrigation water efficiency methods. The primary data set consisted of 210 peri-urban and urban households. It was found that the average cost of illness was higher in peri-urban ($10.79 USD) areas, while willingness to pay for quality water was higher in urban residents. Social status, income, and family size was positively associated with the cost of illness, while education, the source of drinking water (ground water and others), and awareness about safe drinking were negatively associated with the cost of illness. Furthermore, urban residents were more efficient in terms of conveyance and water use. This is one of the first studies to apply irrigation water efficiency methods to measure drinking water efficiency. The results are timely and important with both practical and social implications, including guiding policy framework. It is suggested that family planning programs be made more effective to control family size. The filtration plants to enhance drinking water quality be installed in the central places of each town/division/union council. A public-private partnership could work to provide affordable quality drinking water.
本研究旨在衡量饮用水的功效,包括使用危险水源所涉及的经济影响和患病风险。社会经济因素也被考虑在内。采用多学科方法分析数据,包括疾病成本(COI)、回归技术和灌溉水效率方法。主要数据集由 210 个城郊和城市家庭组成。研究结果表明,城郊地区(10.79 美元)的平均疾病成本更高,而城市居民对优质水的支付意愿更高。社会地位、收入和家庭规模与疾病成本呈正相关,而教育、饮用水源(地下水和其他水源)和安全饮用水意识与疾病成本呈负相关。此外,城市居民在输水和用水方面效率更高。这是首次应用灌溉水效率方法来衡量饮用水效率的研究之一。研究结果具有及时性和重要性,具有实际和社会意义,包括指导政策框架。建议使计划生育计划更有效地控制家庭规模。在每个城镇/分区/联盟委员会的中心位置安装过滤厂以提高饮用水质量。公私合作伙伴关系可以提供负担得起的优质饮用水。
