Ceyranbatan ultrafiltration plant

Submarine Outfall at Ceyranbatan

The Ceyranbatan Ultrafiltration Plant project in Azerbaijan stands out as one of the largest surface ultrafiltration facilities in the world. With a treatment capacity of 520,000 m³ per day, this plant plays a key role in supplying drinking water to Baku, the country's capital, which is home to more than 3 million inhabitants.

Through the use of advanced technologies, this project not only ensures a safe and efficient supply, but also minimizes environmental impact, setting a standard for future water infrastructure.

General project details

Location: Ceyranbatan, Azerbaijan.
Treatment capacity: 520,000 m³ per day.
Population supplied: More than 3 million inhabitants in Baku.

Logistics and technical challenges

The project presented several challenges due to the geological conditions and the characteristics of the lake terrain. However, through the use of advanced tunnel boring machines and dredging techniques, the team successfully overcame these challenges.

Project highlights:

First drilling completed: May 2014.
Dredging and rescue of tunnel boring machinesCompleted at the bottom of the lake, with an estimated completion date of June 2014.
Reduced environmental impactMicrotunneling technique minimized the alteration of the natural environment.

Environmental and social impact

The Ceyranbatan Ultrafiltration Plant not only ensures a continuous supply of potable water, but also reflects a commitment to environmental sustainability.

Conservation of the natural environmentCareful construction preserved the ecosystems of the lake and its surroundings.
Water efficiencySubway pipelines ensure a constant and safe flow of water.
Technological innovationThe use of state-of-the-art tunnel boring machines sets a model for future projects.
