Tainan and Hsinchu desalination plants pass environmental impact assessments, producing 300,000 tons of water per day and increasing annual electricity consumption by 380 million kWh.
In response to climate change, and to prevent the next drought, the Water Resources Agency plans to build a desalination plant on the island. The Environmental Protection Agency held the 423rd environmental impact assessment meeting yesterday (13th) to review the "Tainan Desalination Plant Construction Plan" and the "Hsinchu Desalination Plant Construction Plan", and both proposals were approved. In the future, the two desalination plants will be in operation, with a total water production of up to 300,000 CMD (tons/day), but will also consume 384 million kWh of electricity each year. Water supply has been unstable in recent years. The Water Resources Agency: Building a desalination plant will increase water supply resilience. In recent years, severe droughts have occurred frequently, and the problem of tight regional water supply has come to the fore. Although Tainan has the Zengwen and Nanhua reservoirs, they are greatly affected by the wet and dry seasons. In the past ten years, seven of them have implemented water supply reductions for people's livelihood, industry or irrigation due to low rainfall; Hsinchu has to adjust the water sources of the Shimen Reservoir in Taoyuan and the Yongheshan Reservoir in Miaoli for a long time because the capacity of the Baoyi and Baoer Reservoirs is relatively small. In order to reduce the risk of water shortage, the Water Resources Agency of the Ministry of Economic Affairs plans to build desalination plants on state-owned land along the coast of Jiangjun, Tainan and Nanliao, Hsinchu. At the environmental impact assessment conference yesterday, the Water Resources Agency stated that in addition to Taiwan, record-breaking droughts have also occurred around the world. Taiwan is surrounded by the sea, and the construction of desalination plants will help improve the resilience of water supply. The Tainan Desalination Plant and the Hsinchu Desalination Plant, planned by the Southern District Water Resources Bureau and the Northern District Water Resources Bureau of the Water Resources Agency respectively, passed the environmental impact assessment conference yesterday. The Hsinchu plant covers an area of 10 hectares and has a water production capacity of 100,000 CMD; the Tainan plant covers an area of 17 hectares and will be built in two phases. The first phase will produce 100,000 CMD. After five years of operation, the second phase will be added, and the water production will increase to 200,000 CMD.
