2026-09-10The People's Committee of Hue City, Vietnam, held talks with a delegation from the Japan International Cooperation Agency (JICA) on 9 月 4 日, confirming the advancement of the Phase II Water Environment Improvement Project on the North Bank of the Huong River: total investment of approximately USD 1.85 亿 (JPY 272.6 亿), of which the Japanese ODA loan accounts for approximately USD 1.35 亿. The core scope includes a new centralized wastewater treatment plant with a capacity of 3 万 m³/d (reserved for expansion to 5 万 m³/d), along with supporting pumping stations and sewage collection networks, covering approximately 934 hectares across four districts—Phu Xuan, Kim Long, Hoa Chau, and Huong An—with implementation expected from 2027 to 2032 年.
I. Project Origin: Addressing Direct Sewage Discharge and Flood Control Shortcomings on the North Bank of the Huong River
On 2026 年 9 月 4 日, Hoang Hai Minh, Standing Vice Chairman of the People's Committee of Hue City, Thua Thien Hue Province, Vietnam, held talks with a delegation from the Japan International Cooperation Agency (JICA) to discuss preparations for the Phase II Water Environment Improvement Project on the North Bank of the Huong River (Phase II Project). The project is led by the People's Committee of Hue City, with support from the Japanese side through the Japanese government's Official Development Assistance (ODA) channel, with concessional loans provided by JICA. The coverage area includes four districts—Phu Xuan, Kim Long, Hoa Chau, and Huong An—totaling approximately 934 hectares. This area is located on the north bank of the Huong River and is the core urban development zone of Hue City, featuring an intricate network of rivers, lakes, and waterways, and includes part of the architectural complex of the Hue Imperial City (a World Cultural Heritage site).
Hoang Hai Minh stated during the talks that the core task of the Phase II Project is to build a complete drainage, sewage collection, and treatment system to enhance the water environment capacity and flood control resilience of the area. The implementation of the project will resolve the compound problems that have long plagued the area, including direct sewage discharge, poor water quality, and the intertwining of flooding during the rainy season.
II. Core Works: 3 万 m³/d Centralized Treatment Plant + Pumping Stations + Collection Network
The Phase II Project will include the following core works:
- Centralized Wastewater Treatment Plant—A new centralized wastewater treatment plant with a capacity of 3 万 m³/d, with reserved space for expansion to 5 万 m³/d to meet the medium- and long-term sewage increment demand on the north bank of the Huong River.
- Pumping Stations and Sewage Collection Network—Supporting construction of multiple lift pumping stations and main and branch sewage collection networks covering 934 hectares across the four districts, connecting the existing combined and decentralized discharge systems to the centralized treatment facility.
- Comprehensive Water Environment Governance—Simultaneously advancing dredging, revetment restoration, and aquatic ecological restoration works for waterways and lakes in the core area of the Imperial City and surrounding areas, improving regional water environment quality and flood control capacity.
After the project is implemented, it will significantly enhance the centralized sewage collection and treatment capacity of Hue City, reduce direct sewage discharge into rivers, gradually improve water quality and environmental sanitation, and enhance the quality of life of residents.
III. Funding Structure: USD 1.85 亿 Total Investment, ODA Accounts for Over 70%
The total investment of the Phase II Project is estimated at approximately JPY 272.6 亿 (approximately USD 1.85 亿), with the following funding structure:
- Japanese ODA Loan—Approximately VND 3.52 万 billion (approximately USD 1.35 亿), provided through the JICA channel, serving as the primary funding source for the project;
- Vietnamese Counterpart Funding—Approximately VND 7560 亿 (approximately USD 2900 万), borne by the Vietnamese treasury.
ODA accounts for approximately 73%, and the project execution period is 2027—2032 年, with phased completion of feasibility study approval, bidding and procurement, civil construction, equipment installation, and trial operation.
IV. Continued Growth of Wastewater Treatment in Southeast Asia and a Window of Opportunity for Chinese Equipment Going Global
The Hue Phase II Project is a flagship project for wastewater treatment and flood control in a provincial capital city in central Vietnam, and represents a continuation of Japan–Vietnam cooperation in the fields of Reclaimed Water Reuse and municipal wastewater. Previously, Khanh Hoa Province in Vietnam received approximately USD 8800 万 in ODA support from the Asian Development Bank for sewage infrastructure, and Phu Tho Province received USD 2638 万 in loans from Germany's KfW to support the left-bank sewage project (which has successively entered the trial operation/handover stage). This indicates that municipal wastewater and Industrial Park wastewater treatment projects in Vietnam are being implemented intensively with the support of multilateral financial institutions such as the ADB, JICA, KfW, and WB, forming a stable window of opportunity for equipment going global.
The Hue project is characterized by the integrated delivery of a "3 万 m³/d centralized treatment plant + supporting pumping stations + large-scale pipe network + water ecological restoration," which presents significant supporting opportunities for Chinese water equipment enterprises in membrane pretreatment, biological treatment stages such as MBR / AAO processes, disinfection, sludge dewatering, and automatic control systems.
V. Impact on TIANYI TECH's Vietnam Market Layout
TIANYI TECH has long been building its presence in water markets along the "Belt and Road," and the Hue Phase II project in Vietnam is highly aligned with the company's Southeast Asia business direction:
- Process package for centralized municipal wastewater treatment plants — The 3 万 m³/d scale corresponds to a process combination of pretreatment + AAO / MBR + advanced treatment + disinfection, and the company has the capability to deliver a complete process package.
- Automatic control systems for pipe networks and pumping stations — The sewage collection pipe network covering 934 hectares and multiple lift pumping stations create sustained procurement demand for level gauges, flow meters, valve automation, and SCADA platforms, and the company's automatic control products are capable of direct integration.
- Water ecological restoration — The dredging, bank protection, and water ecological restoration of waterways and lakes around the Imperial City create new order opportunities for constructed wetlands, ecological floating islands, and aeration equipment.
- Extension to O&M trusteeship — The 2027—2032 年 project cycle is long, and demand for long-term O&M trusteeship after completion will continue to expand, allowing the company to work with local partners to provide a combined "construction + 5—10 年 O&M" solution.
