Vinh City continues to maintain field pumping station to prevent flooding
Although the heavy rains after storm No. 4 have ended, the Vinh City People's Committee said it will continue to maintain the makeshift pumping station at Ben Thuy until after the peak of the storm season.
The Flood and Storm Prevention and Rescue Command of Vinh City said: In 2 days (September 23 and 24), due to heavy rain (nearly 300mm in about 12 hours), the amount of water flowing into the area of Pumping Station No. 3 in Ben Thuy area increased, exceeding the processing capacity of the pumping station by 20,000 m3.3/hour. The above factors combined with the high water level of Lam River have limited the drainage of water through Hoi Tri culvert. Therefore, Vinh City People's Committee signed a contract to hire a field pumping station of Nam Irrigation Company Limited to install at Pumping Station No. 3 to prevent further heavy rains.
Immediately after the temporary pumping station was installed and operated for a few hours, from the afternoon of September 24, the rain stopped and the flooding was resolved, so the public questioned whether it was necessary and whether the city would remove or continue to maintain this pumping station.
A representative of the Vinh City Flood and Storm Prevention and Rescue Command said: Although the rain after storm No. 4 and the impact of the Northeast monsoon have ended, it is currently the peak of the storm season and the weather is quite unusual. To prevent the situation of continued heavy rain, exceeding the drainage capacity of the pumping station, the City People's Committee decided to maintain the field pumping station and assign Pump Station No. 3 to manage and operate until the peak of this year's storm season. Depending on the specific situation, the station will decide to temporarily dismantle or reinstall when necessary.
Previously, in September 2019, the pumping station in this area operated with the city's power grid, so when heavy rain caused severe flooding, the entire city lost power and the pumping station could not operate. Therefore, 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 lake, expanding the drainage culvert and increasing the capacity of the pumping station from 5,000 m3/hour up to 20,000 m3/hour.
