In 2005 and within the framework of three successive contracts, the Qatar state public works authority (Ashghal), responsible for the capital city’s wastewater system, called on SUEZ to meet its resource protection goals and support Doha’s demographic and international growth.
Ashghal planned and contracted a phased extension of Doha West wastewater treatment plant, according to a Design Build and Operate procurement model. The original capacity of Doha West wastewater treatment plant was 70,000 m3/day.
