Perceptions of water quality, and current and future water consumption of residents in the central business district of Yangon city Myanmar

Public water supply services in Yangon started in 1842, however the practice of drinking tap water has been uncommon until this moment. Currently, Yangon city development committee is upgrading the tap water system in accordance with the greater Yangon water supply improvement project. It is important to know the perceptual driving factors affecting the decision to drink in order to effectively improve the public acceptance of tap water. In this study, household water management practices and their influencing factors for Yangon city residents are revealed through questionnaires. Residence time in Yangon city is significantly associated with water consumption behaviour. Decisions for drinking come from organoleptic perception rather than important safety considerations. The future consumption of tap water is influenced by income and perception of overall quality. Preferred billing method is associated with education, family size, income and willingness to spend more for better quality water.
