【 摘 要 】

This paper investigates the daily per capita residential water use based on the demographic and socio-economic factors described by Mosaic Hong Kong and provides insights into future water supply planning. A survey was conducted to collect information on household water use behaviours and water consumption patterns. The survey results indicate that considerable consumption differences (in the range of 115.6 to 167.7 litres per person per day) exist among the Mosaic Groups, and the average daily per capita residential water consumption is estimated to be 139.6 litres per person per day. The results also reveal that the daily per capita water consumption is inversely proportional to household size in the range of 2 to 6. Moreover, consumption differences among housing types and districts are reported.
