On the morning of October 2, Nghe An Department of Science and Technology coordinated with Vinh City People's Committee to organize a scientific workshop on Vinh urban drainage - current situation and solutions.

The workshop was chaired by comrades: Huynh Thanh Dien - Vice Chairman of the Provincial People's Committee; Tran Quoc Thanh - Director of the Department of Science and Technology; Nguyen Hoai An - Chairman of the Vinh City People's Committee. Attending the workshop were many scientists from central ministries and branches, representatives of provincial departments and branches.

In recent years, the Vinh City rainwater and wastewater drainage system has been funded by projects from the German Reconstruction Bank and the World Bank to build many important components. The projects have been basically completed, partially solving the flooding and wastewater treatment problems, ensuring environmental sanitation.

However, with the rapid urbanization and increasingly complex climate change, Vinh City still experiences flooding, requiring local authorities to constantly face new challenges.

The workshop on Vinh urban drainage - current situation, causes and solutions received contributions from many aspects, from scientists to find in-depth solutions for each stage, to solve the problem of urban flooding, improve the quality of life for Vinh City.

The workshop listened to researchers report on the current situation and causes of localized and total flooding in Vinh City. Thereby, proposing immediate and long-term solutions.

Mr. Bui Ngoc Thanh - Standing member of the Executive Committee of the Nghe An Urban Planning and Development Association proposed a solution: The entire system of level I, II, III canals needs to be renovated, upgraded, and periodically dredged to ensure the necessary flow. It is possible to adjust and rebuild the sewer line south of the North canal by widening the aperture and sloping back to the North canal at Nguyen Van Cu Street and Road 3 - 2. Build a number of transfer pumping stations to pump rainwater to the North canal.

Some other experts believe that the city needs to build a complete drainage system. Review the entire current drainage network of the city and neighboring affected areas, on that basis, establish a drainage plan for the Nam - Hung - Nghi - Vinh City area combined with irrigation and dyke planning to prevent flooding in the city.

Construct a number of new canals; expand main drainage axes and key drainage culverts. Construct dykes and a number of pumping stations to combine self-flowing and dynamic drainage for low-lying areas. Complete the system of branch and intra-field drainage canals. Strictly manage the implementation of planning, especially for new urban areas to ensure consistency, longevity and efficiency in drainage.

Concluding the workshop, Mr. Huynh Thanh Dien - Vice Chairman of the Provincial People's Committee acknowledged and agreed with the opinions of scientists and experts on urban drainage solutions. In recent years, Vinh City has made efforts to improve the drainage system, but due to limited resources, it has not been built synchronously and the management system is still limited.

Comrade Huynh Thanh Dien requested Vinh City to have a plan for drainage systems, canals, ditches, pumping stations associated with wastewater treatment. Focus on attracting capital sources to plan priority urgent drainage projects; focus on maintaining drainage canals. Drainage must be studied simultaneously with the urban construction process. In addition to the overall solution, there must be detailed solutions for each project, each urban area, each specific project.

In addition, mapping the drainage system database includes diagrams of drainage routes, drainage zones, drainage directions, apertures, and elevations for the drainage system; serving the research, operation, and investment in the construction of drainage works. Especially, during the rainy and flood season, Vinh City needs to coordinate drainage with other sectors better to drain floods.

Flood drainage in areas of color is a 'talked about' story

(Baonghean)- Nghe An currently has over 20,000 hectares of vegetable and color production, which plays an extremely important role in the province's agricultural production. However, for many reasons, the irrigation system for color areas has not been properly invested in and still has many shortcomings.
