Degremont and Marubeni win Doha wastewater deal

Pair clinch $220mn contract to expand treatment and recycling plant.


Degremont and partner Marubeni have been chosen to expand the Doha West wastewater treatment and recycling plant.

The contract is worth EUR 178mn ($220mn) with Degremont, a subsidiary of Suez Environnement, to pocket EUR 94mn of that.

Following the work, the capacity of the plant will be 280,000 m3 per day, up from 175.000 m3 per day previously.

Over the term of the contract, the plant will be able to manage the wastewater of 1,040,000 population equivalent from Doha city.

This project follows the two contracts signed in 2005 for the design, construction and 10-year operation of a 135,000 m3 per day plant, then in 2011 for its first expansion to 175,000
m3 per day.

Located 20km west of Doha, the plant has been in operation since March 2010, the 2011 expansion was completed in late 2012, and SUEZ ENVIRONNEMENT will oversee the plant’s operation until 2020.

“This new contract acknowledges our capacity to offer, deliver and then operate efficient facilities tailored to the local challenges of population growth and protection of resources,” said Remi Lantier, CEO of Degrémont.

To confront Doha’s increasing population, Ashghal essentially chose the same technologies that have already been put in place and proven effective: expansion of the secondary biologic treatment, and expansion of the tertiary treatment which implements ultrafiltration membranes and the Smartrack™ system, thus allowing re-use of the treated water to irrigate green spaces, market gardens, and to replenish groundwater.

This contract strengthens the presence of SUEZ ENVIRONNEMENT in Qatar where it also designed and built wastewater treatment facilities for Barwa City (50,000 inhabitants) and Lusail (250,000 inhabitants), which use treated water to re-vegetate desert parcels of land and, over time, to maintain green spaces throughout the artificial Pearl Island.
