The SUEZ solution? Propose efficient and scalable infrastructures to protect the water resources while meeting the growing needs of the capital. We built a new wastewater treatment and recycling plant on the Doha West site; and extend the facility capacity to meet the needs of Doha.
Scalable solutions to increase the water treatment capacity
In 2005, the city of Doha signed an agreement with SUEZ for the design, build and operation of a new wastewater treatment and recycling plant located west of Doha. The new wastewater plant came into operation in March 2010, supplementing the production of the existing plant on the Doha West site. The following year, State authority Ashghal entrusted SUEZ with the extension of the Doha West wastewater plant, as the needs of the population already exceeded the capacity of the plant. The objective: raise daily production from 135,000 to 175,000 m3 using the same technology. The extension was brought online in July 2012, three months ahead of schedule.
Ensure sufficient water supply for the FIFA 2022 world cup infrastructures
In 2015, SUEZ was again assigned to extend the Doha West wastewater treatment and recycling plant by 2017. This time, the intended capacity amounted to 280,000 m3 per day. The same year, the management authority of the Aspire Zone contracted SUEZ to design and build a post-treatment plant. The idea is to reuse a part of the wastewater recycled by the Doha West site for the needs of the 250-hectare sports complex, including the FIFA 2022 world cup stadium. We adjusted the quality of recycled wastewater to the specific requirements of the Aspire Zone and guarantee plant performance in terms of quantity.
Increase the volumes of water available without reducing natural resources
Through advanced technologies, such as ultrafiltration membranes, the Doha West plant can reuse 100% of treated wastewater. The wastewater is reused for agriculture in the desert (55%), gardens (42%), and recharging aquifers (3%).
