| Abstract | The objectives of this study are to examine the water consumption characteristics in Bangkok, develop water demand models, evaluate the effect of water conservation measures and propose some recommendations to the Metropolitan Waterworks Authority (MW A), in order to promote sustainable urban water demand management in Bangkok. The data on the water use and the factors affecting the water demand such as water utility management policy factors, socioeconomic characteristics and climatic factors have been collected from the MWA and other related agencies. Water consumption characteristics have been analysed by developing water demand models for the three cases, i.e. residential sector, nonresidential sector and total water demand. The analysis has been carried out using multiple regression technique with SPSS software. The results indicated that the number of connections and the average price are the most important factors affecting the water demand for all the three cases. Average household size is significant for the residential sector as well as for total water demand. Rainfall has been found to be significant for the nonresidential sector only. A log-log model is found suitable for the cases of residential sector and total water demand, whereas a linear model is fitted well for nonresidential sector. Water demands have been forecasted using the developed model and compared with those estimated by the MWA master plan (1990) and the demand side management (DSM) study (1996). The demand estimated by these studies have been found to be much higher than the present study. The study evaluated the public awareness program as a conservation measure and found that its implementation is economically viable. The results of some case studies on demand management showed that there is a large scope of water-use reduction in case of high water consuming customers with the adoption of various conservation measures, such as retrofit, leak detection and repair and public awareness program. The study recommends that considerable savings in water use can be attained through the implementation of comprehensive water demand management programs, which can help meeting the growing demand for other economic sectors as well as delay the investments for new water supply sources. |
