| Abstract | This study assesses water footprint (WF) of tap water from the Maha Sawat Water Treatment Plant (MS-WTP), Metropolitan Waterworks Authority (MWA), Thailand. The method for water accounting is based on water footprint network method in combination with life cycle assessment concept. The data used in the assessment is collected from the MWA with yearly basis of fiscal year 2013. This cradle-to-gate assessment comprises of the operational water footprint (the amount of blue water usage and loss in process) and the supply-chain water footprint (the amount of blue water embodied in electricity and chemicals). The total WF of tap water from the MS-WTP is about 1.6024 m3 per 1 m3 of tap water. The hotspot is in the distribution system which should be the leakage in pipeline network. The MWA also concerns about this issue and has the policy to reduce the water loss in pipeline system. When considering the water stress index (WSI) of the Mae Klong basin, the water deprivation of MS-WTP tap water is 0.0288 m3H2Oeq. The full capacity expansion of MS-WTP will increase the WSI of the Mae Klong basin from 0.008 to 0.024 which is still classified as the low water stress. The WF gives more clearly about the efficiency of water usage and the hotspot process. The WF can help increase the public awareness of water usage. Future studies should extend the assessment scope to all of water treatment plants of MWA and the analysis should be based on monthly basis in order to capture the seasonal effect. |
