United Water joins hands with Tianjin Municipal Engineering Design & Research Institute to ensure high-quality implementation of Package 10 of Saudi National Water Company's long-term O&M project

en.Wedoany.com Reported - On November 9, Jiangsu United Water Technology Co., Ltd. and Tianjin Municipal Engineering Design & Research Institute Co., Ltd. signed the design contract for Package 10 of the Saudi National Water Company's long-term municipal wastewater O&M project and a long-term strategic cooperation agreement at United Water's headquarters. The project covers 9 wastewater treatment plants across 4 provinces in northern Saudi Arabia, with a total treatment capacity of 337,800 cubic meters per day and an operation and maintenance period of 15 years. The project has completed on-site geological surveys, geophysical exploration and mapping, and is about to enter the engineering design phase.

The signing ceremony was completed by Liu Meng, Director and Executive President of United Water, and Cao Jing, General Manager of Tianjin Municipal Engineering Design & Research Institute, on behalf of both parties. Tianjin Municipal Engineering Design & Research Institute will undertake the design tasks related to Package 10, and the two parties will collaborate on preliminary survey results, engineering design, and subsequent procurement, construction and operation. This signing marks further advancement of the engineering design work following the formal signing of the long-term operation and maintenance agreement on September 1, 2026.

Package 10 is distributed across Hail Province, Qassim Province, Al-Jouf Province and Northern Borders Province in Saudi Arabia, involving the process, equipment and in-plant pipeline network rehabilitation and upgrading of 9 municipal wastewater treatment plants, as well as the construction of advanced sludge treatment facilities. According to the project agreement previously disclosed by United Water, the cooperation period is 15 years, with the first 3 years including rehabilitation work without shutting down operations. The estimated total revenue during the operation period is 1,305.6 million Saudi riyals, approximately RMB 2.366 billion. The total project investment is approximately 190 million Saudi riyals, to be implemented by a project company led by United Water.

The two parties will also extend their cooperation to Package 11 of the Saudi National Water Company's long-term O&M project, as well as domestic and international water supply and drainage, seawater desalination, wastewater treatment, watershed management and municipal infrastructure businesses. The cooperation covers investment, engineering general contracting, design and procurement, and operation management. The two parties will establish a regular collaboration mechanism, share project market information and technical resources, and jointly carry out engineering development and design services.

United Water won the bid for Package 11 of the Saudi National Water Company's project in August 2026. The project is located in Medina Province, covering 5 wastewater treatment plants with a total treatment capacity of 442,000 cubic meters per day. The long-term strategic cooperation agreement signed with Tianjin Municipal Engineering Design & Research Institute incorporates Package 11 into the scope of subsequent collaboration, to be advanced separately from the specific design contract already signed for Package 10.
