en.Wedoany.com Reported - China Railway No.4 Engineering Group Co., Ltd. (CREC4) officially signed an EPC turnkey contract for Phase I of the Ras Al Khaimah Sewage Treatment System on June 12, 2026, in the UAE with developer Etihad Water and Electricity (EtihadWE), France's Saur Group, and the water division of Abu Dhabi National Energy Company (TAQA). The project is designed with a daily treatment capacity of 60,000 cubic meters, capable of meeting the sewage treatment needs of approximately 300,000 people upon completion. The contract value is about USD 120 million.
CREC4 is a core subsidiary of China Railway Group Limited (CREC), headquartered in Hefei, Anhui Province. Its predecessor was the Railway Engineering Corps of the Chinese People's Volunteers, established in 1950. It is now a mega-scale construction enterprise group integrating engineering construction, design, investment, and operations, with business spanning over 30 countries and regions worldwide. In recent years, CREC4 has been actively expanding in the overseas water and environmental protection sector, undertaking major projects such as the Ulaanbaatar Central Wastewater Treatment Plant in Mongolia.
The developer consortium consists of three parties: Etihad Water and Electricity (EtihadWE) is a state-owned utility established in 2020 under Federal Law No. 31, wholly owned by the UAE Investment Authority, responsible for supplying electricity and fresh water to the northern emirates (including Ajman, Umm Al Quwain, Ras Al Khaimah, Fujairah, and Dhaid), serving approximately 2 million people; France's Saur Group, founded in 1933 and headquartered in Paris, is a leading European water and environmental services company specializing in drinking water production, wastewater treatment, and waste resource recovery; Abu Dhabi National Energy Company (TAQA), established in 2005 and headquartered in Abu Dhabi, is listed on the Abu Dhabi Securities Exchange (ADX: TAQA), with operations spanning power and water, as well as upstream and midstream oil and gas.
Under the contract, CREC4 is responsible for the construction of gravity sewage pipes, reclaimed water transmission pipes, and related pumping stations. Located in the northern emirate of Ras Al Khaimah, the project is the largest sewage treatment infrastructure project in the emirate. Upon completion, it will collect sewage through approximately 6.3 kilometers of gravity pipelines and transmit reclaimed water through a network extending up to 26 kilometers. The plant also reserves expansion capacity, with future potential to reach 150,000 cubic meters per day. The Ras Al Khaimah Government's Public Services Department signed a long-term sewage treatment agreement on behalf of the emirate.
This signing marks a significant achievement for CREC4 in deepening its presence in the UAE market and represents another breakthrough for Chinese enterprises in the water infrastructure sector in the northern UAE region. Upon completion, the project will significantly enhance Ras Al Khaimah's water environment management capacity and water resource recycling level, providing strong support for the local city's green, low-carbon, and sustainable development.
