Water Solutions

Water scarcity, which affects 40% of the population, is increasing because of global warming. ACCIONA plays its part through work in the desalination sector. The company is a global leader in the construction of desalination plants using reverse osmosis technology, which is more efficient, less energy intensive and has a smaller carbon footprint than conventional thermal desalination.

+ 5 million of m³/day treated in desalination plants

Our progress in 2021


the desalination plant will have a daily capacity of 570,000 m³ to supply 2 million people. Once the plant is completed, ACCIONA will supply around ~2.4 million m³/day of desalinated water in Saudi Arabia using reverse osmosis technology.

ACCIONA has been commissioned to build the Jebel Ali reverse osmosis desalination plant, one of the largest reverse osmosis desalination plants in the UAE. This project supports the Dubai Clean Energy Strategy 2050, whose goal is to have 75% of the country’s total energy capacity coming from clean energy sources by 2050.

182,000 m³/day drinking water produced

A third of the world's population still lack access to drinking water. In a situation exacerbated by the climate emergency, ACCIONA develops water treatment solutions to make water safe or fit for consumption. It is designing water treatment infrastructure, to add to the facilities it has already built, to provide a safe access framework for more than 41 million people worldwide.

+ 125 drinking water treatment plants with a total capacity of 8.5 million m³/day

ACCIONA has built more than 125 drinking water treatment plants with a total capacity of 8.5 million m3/day which supplies more than 41 million people.

Our progress in 2021

ACCIONA has begun to install the seven kilometres of 1,500-millimeter-diameter pipes that will distribute the treated water at the Arraiján drinking water treatment plant, the Ingeniero José G. Rodríguez in Panama.

ACCIONA has built two new flotation lines at the DWTP, doubling the plant’s capacity to produce drinking water. The works have improved the facilities to increase the water supply in the area, guaranteeing the supply to the entire region in times of greater water scarcity. This increase in supply capacity will also respond to the particularities of the region’s raw water, and will reinforce the characteristics of the new treatment scheme, supplying the entire perimeter of the Algarve.

+1 M Equivalent inhabitants

20 million m3/day capacity

484 Hm3 of treated waste water

Four billion people in the world do not have access to basic sanitation services. Moreover, more than 80% of the wastewater produced by humans is discharged into rivers and seas without prior treatment. In response to these problems, ACCIONA uses innovative treatments in the development of water treatment projects, including biological purification processes, sludge minimisation and reuse of treated water.

ACCIONA has built more than 330 wastewater treatment plants with a total capacity of 20 million m3/day which serves more than 70 million people

The Bahr al-Baqar wastewater treatment plant, located in northwestern Egypt, is one of the largest in the world and the largest in Africa. ACCIONA was responsible for the process engineering, electromechanical equipment and supervision of the assembly and commissioning of the plant, guaranteeing the specified quality and treatment parameters, selecting and supervising the plant’s equipment and processes.

5,6 million m3/day treatment capacity

44 % of water used in facilities is from rainwater, recycled and reused

484 Hm3 of water used in facilities is from rainwater, recycled and reused

ACCIONA researches innovative technological in the area of water reuse to design sustainable solutions for use in agriculture, urban parks and other activities. The company constantly researches technological developments for the reuse of wastewater, enabling a wider use of purified water.

Our progress in 2021

  • Nhieu Loc-Thi Nghe wastewater treatment plant

The design-build portion of phase 1 for the Nhieu Loc-Thi Nghe wastewater treatment plant is underway in Ho Chi Minh City (Vietnam). The contract is financed by the World Bank and is worth €200 million. The wastewater treatment plant project will have a capacity of 34,000 m3/h, equivalent to the needs of 1M equivalent population.

EDAR Moratalla


ACCIONA has implemented an ultrafiltration system at the Moratalla WWTP in Murcia, which improves tertiary treatment at the plant. This ensures compliance with the new limits proposed by the European Union on reuse and part of this water can be used for agricultural irrigation.

4,500 m3/d treatment capacity

+ 30 years offering full water services to support sustainable development in urban centers

Cities are the most important hubs and centres for human progress. As such, they also pose many challenges, such as overpopulation, which require water infrastructure and sustainable water resource management to ensure a proper supply of water.

Our progress in 2021

  • GOTA Project

In 2021, it was carried out the digitization of the municipality's supply network of Andratx (Mallorca) to manage water resources more efficiently and providing a better service to its clients. The network has also been micro-sectorized to take instantaneous readings and detect any anomalous levels quickly and reliably.
