A consortium of Acciona Agua and VINCI Construction Grands Projets has secured a contract to design and build the phase 1 of the Nhieu Loc-Thi Nghe wastewater plant in Ho Chi Minh City in Vietnam.

Acciona said that the total contract is worth €200m and once constructed, the plant will have a peak capacity of 34,000m3 per hour. The design, build portion of the contract is expected to take five years for completion, including the starting-up process and acceptance of works. The scope of the contract also includes operations and maintenance of the plant, for a period of five years.

The wastewater treatment project consists of a pumping station, biological treatment, disinfection, sludge treatment, odour treatment as well as connection to the city’s sewage system.

It will treat wastewater from the Nhieu Loc-Thi Nghe Basin and is expected to become an essential part of Ho Chi Minh City’s second environmental plan and serving more than a million residents.

During the construction phase of the project, up to 800 local workers could be hired. Also, about 25,000 hours of training is planned to be given to ensure workers’ safety at the worksite.

The firm, in a statement, said: “Although Vietnam is rich in water, supply is problematic as weather and terrain hamper storage. As a result, modernisation of the infrastructures is one of the central axes of the water management policy implemented in Vietnam in recent years; this wastewater plant is part of that process.”

The contract is claimed to be the first for Acciona in Vietnam and it strengthens its footprint in Southeast Asia, a market with considerable potential for infrastructure projects. Acciona first entered the market through a contract in the Philippines in 2016.

Last month, the Spanish company renewed its contract to operate and maintain 15 of the wastewater plants owned by Madrid’s water company Canal de Isabel II in the Jarama Medio and Henares watersheds. The renewed contract for the 15 plants, which serve about 1.25 million people by processing about 80 million m3 per year, will last for five years.
