DM Bandula Bandara, DPS Chandrakumara

The bottled water was introduced into the Sri Lankan market in the late 1980s. It began to expand a decade later in 1990s. Since then, with the interference of the government, this market has been expanding continuously. However, no systematic research has been carried out so far for analyzing the demand and supply behavior of the bottled water market. The aim of this study was to identify the determinants of migrants’ demand for bottled water in the City of Colombo in Sri Lanka. The literature review revealed some important variables that determined the demand for bottled water. The methodology consisted descriptive statistics and an estimation of the demand function using Binary Logistic Analysis. The analysis was based on primary data which was collected from three popular tourist places in the city of Colombo. Finally, the study unveiled the key determinants of the migrants’ bottle water demand. The age, education level, and the monthly income of the family of the migrants were found to be the three main determinants of the demand. With the increase of income and education of people, the demand for bottled water can be expected to rise in the future. Since the low income people have no concern on the safety and hygienity of water, the government should take action to improve the quality of water provided as a public utility.
