Reporter Dai Yuxiang / Taipei Report
As the water storage capacity of the reservoir in the Jianan area is estimated to be insufficient to meet the needs of next year’s rice cultivation, the Jianan area will stop irrigating for next year’s rice cultivation. In addition, the Central Meteorological Office estimates that the anti-Santo Infante phenomenon will continue from February to April next year. Rainfall may be low, which has increased Taiwan’s water shortage crisis, and the issue of building a reservoir has been discussed again. The Ministry of Economic Affairs is currently planning three new reservoirs in the north, center and south, including New North Shuangxi, Miaoli Tianhua Lake and Tainan Nanhua (the second reservoir), in addition to the “Increased Dams” plan for 7 reservoirs in Taiwan. In addition, it is expected to help Taiwan weather a hundred years of drought.

The construction of three new reservoirs is currently planned at New North Shuangxi, Miaoli Tianhua Lake and Tainan Nanhua (the second reservoir). If completed, they can supply 126,000 tonnes, 260,000 tonnes and 170,000 tonnes of water per day, respectively, but currently except Shuangxi. The second-order environmental assessment report was completed, Tianhua Lake is still undergoing further ecological investigations, and Nanhua No.2 is still being planned.
“To complete the regional shipment, we must have reservoirs,” said Wang Yifeng, deputy director of the Department of Water Resources, in an interview with Sanli News. Due to our rains, the Taiwan region is divided into dry periods and wet periods. The volume of water varies greatly. We need there are reservoirs to “store abundance and help drought.” With climate changes, it is easy for us to find abnormal rains during high tide periods, and regional shipping becomes very important.

Wang Yifeng said that there are currently 95 reservoirs in Taiwan with a total storage capacity of 2.9 billion tons. However, such storage capacity must be strengthened to face the risks of future climate change and increase regional water use.“But because there are many opinions related to the construction of reservoirs, in the short term, we will give priority to low-flow water, reclaimed water and the construction of artificial lakes. In the long term, we still expect several projects to be in planning and promotion. The reservoir can be completed, but there is no timetable for its promotion. “
The Department of Water Resources is currently on the part of reservoir dredging, which is to maintain the existing functions of the reservoir. He has set a goal: “I hope that by the ROC year, 13 reservoirs can deposit zero growth.”
In addition, the Department of Water Resources plans to “dam up” seven former reservoirs in Taiwan. Wang Yifeng said that the Zengwen Reservoir, which provides 55 million tons of water and 110 million tons of water every year, has been completed. Currently, the Nanhua and Baoer reservoirs are still underway, and the Shimenhouchi, Liyutan, Xishi and Mudan reservoirs are under feasibility assessment.
