In 2025, despite unfavourable weather conditions, Quang Tri Province made concerted efforts to complete reservoir upgrading and repair projects and put them into operation for this winter–spring crop.
At present, the province’s irrigation system is relatively comprehensive, including 273 reservoirs, 413 weirs, and hundreds of irrigation, drainage, sluice, and salinity-prevention works. The system ensures water supply for more than 102,400 hectares of rice, nearly 3,000 hectares of other crops, and more than 3,400 hectares of aquaculture, while also providing water serving daily life for millions of residents. The reservoirs also play an important role in flood mitigation and flow regulation, helping to protect safe downstream areas.
Investment in repairing and upgrading irrigation works is both urgent and a long-term requirement. The province has mobilised support from the central level and prioritised funding for upgrading irrigation facilities, particularly severely degraded reservoirs. During the 2023–2025 period, many reservoir repair and upgrading projects in the locality were implemented, notably the urgent repair project of Vuc Tron Reservoir with a total investment of over 123 billion VND. This large-scale irrigation work now has a storage capacity of over 64.4 million cubic metres after upgrading. It plays a vital role in irrigating more than 2,000 hectares of agricultural land and nearly 150 hectares of aquaculture, supplying domestic water, and serving industrial facilities, especially thermal power plants at the Quang Trach Power Centre, while also regulating floods and protecting downstream safety.
Although upgradation in 2025 frequently faced heavy rains and floods, decisive direction from investors and local authorities enabled contractors to organise flexible implementation, mobilising manpower and equipment to work continuously during favourable weather conditions to ensure both progress and quality. So far, the main components of the project have been completed and put into operation, and upheld clear effectiveness.
Along with Vuc Tron Reservoir, other reservoirs such as Trooc Vuc and Da Lam were also upgraded and completed in 2025. The completion of these projects has enhanced disaster prevention capacity and ensured safety of the lives and property of local people.
Dinh Khanh Hau, Director of the Project Management Board for Agricultural and Environmental Construction Investment of Quang Tri Province, stated that during the project implementation process, a key requirement was to both organise construction and ensure irrigation for production and drainage during heavy rainfall, while most projects were carried out simultaneously in 2025. Despite unfavourable weather conditions, investors and contractors worked with high responsibility to maintain construction progress and quality.
Prior to the administrative unit merger, more than 98% of communes in the former Quang Binh Province and 95% of communes in the former Quang Tri Province met criteria on irrigation and disaster prevention. Following the merger, Quang Tri Province has continued to consolidate and enhance these standards, creating an important foundation for improving the quality of new-style rural area construction in the following period.
In parallel with reservoir upgrades, Quang Tri Province is preparing to implement the key Khe Muoc–Ben Than irrigation complex, with a total expected investment of more than 1,650 billion VND. Once completed, the project will provide irrigation water for over 2,900 hectares of farmland, supply domestic water to approximately 69,000 households, and serve Quang Tri Province’s Southeast Economic Zone. The Quang Tri Provincial People’s Committee has assigned relevant departments and agencies to review and assess current irrigation, drainage, and water supply conditions; calculate water demand for agriculture, domestic use, and industry; and study minimum flow requirements to ensure downstream ecological environment and prevent saltwater intrusion. Technical plans and key works are being carefully examined to minimise land acquisition, particularly production forest land, and to optimise investment capital.
The upgrading of key irrigation works has helped reinforce the foundation of Quang Tri’s irrigation infrastructure. These focused and prioritised investments, aligned with local practical needs, have contributed to improving the efficiency of capital use, maximising the functionality of irrigation facilities, and creating an important driving force for socio-economic development, ensuring social security, and improving living standards for people. They are also a foundation for Quang Tri Province to continue building sustainable agriculture and effectively adapting to climate change in the future.
