[Reporter Wang Hanping/Report from Tainan] In order to improve the problem that the water in the inner area cannot be drained when the water level of Zengwenxi is high, the emergency improvement project for the replacement of drainage and pumping equipment in Shizise is expected to be completed by the end of April this year and completed before the flood season next year.

According to the Nanshi Water Conservancy Bureau, in the Shizilai drainage catchment area of ​​Da Nei District, the water control measures are implemented in a two-pronged approach, and the improvement is divided into high and low areas. The drainage of the highland slopes has completed a 4,200 cubic meter capacity grit chamber and a comb dam, which can regulate the flow of soil and sand and reduce water pollution. The soil and sand accumulation of the drainage road also has the function of flood detention, which can effectively improve the drainage problem of slope land.

Due to the influence of the water level of the Zengwen River in the lowland area, the downstream lowland area cannot be vented and drained. Two pumping stations, Shizise Pumping Station (1cms) and Shizise Pumping Station 2 Stations (2cms), were set up to assist in venting the internal water and reduce the water flow in the downstream area. Risk of flooding.

The Water Conservancy Bureau pointed out that this year, it has sought funds from the central government and invested a total of 36 million yuan in the city's budget. The emergency improvement project for the renewal and pumping of Shizilai drainage and pumping equipment includes adding 3cms pumps to increase pumping capacity, installing sewage removal equipment to prevent pumps from clogging, and expanding the stable pumping capacity of the forebay. , complete the overall function of the pumping station.

In order to improve the problem that water cannot be drained from the inner area when the water level of Zengwenxi rises, the emergency improvement project for updating the drainage and pumping equipment in Shizise is expected to be completed by the end of April this year.
