Vinh City continues to maintain a mobile pumping station to combat flooding.
Although the heavy rains following Typhoon No. 4 have ended, the Vinh City People's Committee announced that it will continue to maintain the temporary pumping station at Ben Thuy until after the peak of the rainy season.
The Vinh City Flood and Storm Prevention and Rescue Command Center reported that: Over the two days (September 23rd and 24th), due to heavy rainfall (nearly 300mm in approximately 12 hours), the amount of water flowing into Pumping Station No. 3 in the Ben Thuy area increased significantly, exceeding the station's processing capacity of 20,000 m³.3/hour. The above factors, combined with the relatively high water level in the Lam River, have limited flood drainage through the Hoi Tri sluice gate. Therefore, the Vinh City People's Committee signed a contract to rent a temporary pumping station from Nam Irrigation Company Limited to be installed at Pumping Station No. 3 to prepare for continued heavy rainfall.
Immediately after the temporary pumping station was installed and operated for a few hours, starting from the afternoon of September 24th, the rain subsided and the flooding was resolved. This led the public to question whether it was necessary and whether the city would remove or continue to maintain this pumping station.
Representatives from the Vinh City Flood and Storm Prevention and Rescue Command Board stated: Although the rain following Typhoon No. 4 and the effects of the Northeast monsoon have subsided, the peak of the rainy season is currently underway, with rather unusual weather patterns. To prevent further heavy rainfall exceeding the pumping station's capacity, the City People's Committee has decided to maintain the temporary pumping station and assign its management and operation to Pumping Station No. 3 until after the peak of this year's rainy season. Depending on the specific situation, the station will decide whether to temporarily dismantle or reinstall it as needed.
Previously, in September 2019, the pumping station in this area operated in conjunction with the city's power grid. Therefore, when heavy rains caused severe flooding, the entire city lost power, rendering the pumping station inoperable. Consequently, along with investing in a separate 3-phase power line and substation to serve Pumping Station No. 3, the city also invested in upgrading the regulating reservoir, expanding the drainage system, and increasing the pumping station's capacity from 5,000 m³.3Up to 20,000 m/hour3/hour.
