Qatar’s treatment works waters manmade forest

The region's largest manmade forest will be irrigated by sewage treatment works, substantially reducing the use of desalinated water for irrigation.

Located near Umm Slal Ali, 25km north of Doha, and adjacent to the Doha North Sewage Treatment Works, massive undertaking to create the region’s biggest manmade forest is underway.

Qatar’s manmade forest will be irrigated by Doha North Sewage Treatment Works, which aims to reduce the use of desalinated water for irrigation.

The largest manmade forest in the region is set to become home to a variety of birds and plant species.

Located near Umm Slal Ali, 25km north of Doha, and adjacent to the Doha North Sewage Treatment Works, a massive undertaking to create the region’s biggest manmade forest is underway.

The forest will cover an area of 8.3km² with 95,000 trees comprising 28 species, all selected for their abilities to withstand the harsh local climate.

There will also be four lakes across 280,000km² and each will have trees, serving as bird and wildlife sanctuaries.

However, irrigation of this vast piece of manmade land will require significant water, so the Doha North Sewage Treatment Works will play a major role in sustaining this forest.

This QAR3.63bn (approximately $997m) plant is the first in Qatar to use techniques such as ultrafiltration and ultra-violet technology to treat sewage water.

The plant, which started operations in February this year, processes sewage to produce water that can be used for irrigation, aimed to reduce the use of desalinated water for plants and crops.

Work started on the forest project in early 2015 and is due to be complete by March next year.

It was designed as a ‘buffer zone’ for the sewage plant, public works authority Ashghal previously said.

Qatar authorities have been working in recent years to increase the number of green and natural areas in the country.

The Ministry of Municipality and the Environment (MME/Baladiya) has also been upgrading existing parks while building new ones.

So far, around 30,000 of the trees have been planted and the lakes have been dug and filled, Rafi Ohanian, operations director at Nakheel Landscapes, told Doha News.
