Our plants have three types of water sources, specifically third party sources, surface freshwater, and seawater. The wastewater (sludge) discharged after treatment along Taiwan's west coast includes third party terminals and seawater.

Water resource risk and impact assessment

The AWARE method is used for assessing water resource risk and impact assessment. The method assumes decreasing water supply in each area to assess the potential effect of water shortage on human beings or the ecosystem (Boulay et al. 2016). The method divides Taiwan into 23 areas, which are shown in the figure below, in which Yunlin County is not an area with high risk of water shortage (water consumption is lower than the global average 75% of the time). Based on the method proposed by Boulay et al. (2016), we divided Mailiao Plant into the following areas:
