Sharing experiences from applying the urban rainwater drainage model towards sustainability and developing a roadmap for drainage service prices in the Mekong Delta

Workshop on sharing experiences from applying the model of sustainable urban rainwater drainage (SUDS) and building a roadmap for drainage service price in the Mekong Delta (Mekong Delta) in the morning of June 18 in the City. Can Tho. The workshop was jointly organized by the German Ministry of Construction and Development Cooperation Organization (GIZ). Assoc.Prof.Dr. Mai Thi Lien Huong – Director of Technical Infrastructure Department, Ministry of Construction and PhD. Tim McGrath – Director of the Mekong Delta Drainage and Flooding Program (FPP), GIZ, hosted the Workshop.


120 participants attended the workshop were leaders and senior experts of Departments of Ministry of Construction, Provincial People’s Committee, Department of Construction, Department of Finance, Department of Natural Resources and Environment from Mekong Delta and Central provinces of Vietnam. , international organizations such as Japan International Development Agency (JICA), Swiss Federal Economic Bureau (SECO), Haskoning Company…

Sustainable urban rainwater drainage (SUDS) is a solution to slow and reduce urban surface flow, thereby reducing the risk of flooding for people, preventing pollution, and supply grant and enhance urban green space. For the community, the benefits of SUDS include improving health, space and quality of life, which can increase the value of real estate and the prosperity of the local economy.

At the workshop, participants shared and summarized the lessons learned during the pilot process of building and applying the model of sustainable urban rainwater drainage in three cities of Ca Mau, Long Xuyen and Rach Gia, replicating the model on the basis of newly issued national and provincial regulations and guidelines such as: (1) Circular No. 22/2019 / TT-BXD dated December 31, 2019 of the Ministry of Construction formulating and promulgating national technical regulation on construction planning with quite specific provisions related to drainage planning, some solutions of urban rainwater drainage in a sustainable manner; (2) Guidance on designing a sustainable urban drainage system published by the Department of Technical Infrastructure – Ministry of Construction and GIZ; (3) Guidance on the application of SUDS in localities is approved by the People’s Committees of some provinces participating in the FPP Program.

Delegates agreed on integrating this model into drainage planning to ensure sustainability and cost effectiveness, towards building climate-resilient, green and smart cities. . In fact, in addition to the design and pilot construction of SUDS in the three cities mentioned above, SUDS solution has been integrated into urban drainage planning of Long Xuyen, Rach Gia and Ca Mau cities due to FPP program support.

Assoc.Prof.Dr. Mai Thi Lien Huong said that in recent years, the model of sustainable urban rainwater drainage has been approached by Vietnam’s drainage agencies and experts. The basic and technical principles of the SUDS model have been learned from international experience, but the way to put these principles and techniques into practice is still difficult. Therefore, Vietnamese partners highly appreciate the support of the Government of Germany and Switzerland, through GIZ, which has successfully piloted the SUDS model in three cities of Long Xuyen, Ca Mau and Rach Gia, thereby helping us gain experience and see more clearly how to apply the SUDS model in practice, thereby contributing to replicating this model to many localities across the country. The training workshop to implement SUDS implementation, co-organized by GIZ and the Ministry of Construction on the same day, also aims to replicate this model.

The price of drainage service was first included in Decree 80/2014 / ND-CP on drainage and wastewater treatment, which applies the principle that polluters pay. Accordingly, the localities calculate the costs and build a roadmap for the price of the drainage service in order to create a stable source of income for the drainage service, ensuring to gradually offset the cost of the drainage service, gradually reducing subsidies. from the state budget for drainage services and increasing the awareness of “discharging households.” According to Ms. Truong Thi Thu Thanh, Deputy Director of Department of Construction Economics – Ministry of Construction, Circular No. 13/2018 / TT- MOCD dated December 27, 2018, guiding the method of pricing drainage services to overcome the shortcomings of Circular No. 02/2015 / TT-BXD, and based on the principle of correctness, adequacy and transparency to mobilizing investment resources and trading services from the private sector, but in the process of implementation, localities also faced some difficulties such as lack of data related to the status of the drainage system, lack of work norms and cost norms … In recent years, GIZ has supported more than 15 provinces and cities of Vietnam to successfully build a roadmap for drainage service prices.

At the seminar, Dr. Tim McGrath – FPP Program Director said, “We are working hard to replicate the main results of the Program in all Mekong Delta provinces, and prepare for the new phase. Focusing on promoting links of 13 Mekong Delta regions with a view to sustainable development. “He also presented more about the idea of a new project with the main areas of activity: institutional strengthening, Mekong Delta planning ….

The project idea was supported by representatives of Mekong Delta provinces and cities attending the workshop.

The FPP program is co-sponsored by the German Federal Ministry for Economic Cooperation and Development (BMZ) and the Swiss Federal Economic Bureau (SECO). The goal of the program is to increase the capacity of central and local governments, increase urban adaptive sunshine and protect people’s homes and income from the impacts of inundation in the three urban areas of Dong. by the Mekong River.
