Qatar’s Public Works Authority (Ashghal) plans to double its production capacity of high-quality treated water from 183 million cu m to 366 million cu m over the next five years.
The news was revealed by Ashghal president Nasser bin Ali Al Mawlawi during a wastewater seminar in Doha, the Gulf Times reported.
Mawlawi said that projects under way included a sewage treatment plant (STP) in Al Thakhira, the fifth package of expansion work for the Doha West STP, the Doha North STP, and the second package of the expansion for the Industrial Area STP. This was in addition to a major STP project in southern Doha, which will have a capacity of 500,000 cu m per day, and will be built as part of the Inner Doha Re-sewerage Implementation Strategy (Idris).
Al Mawlawi said that over the last decade Ashghal had increased its production of treated water from 55 million cu m in 2005 to 183 million cu m today.
He said Ashghal had set design standards for treated water. “These include multiple processing stages to reach advanced tertiary treatment levels by means of microfiltration membrane technologies, which have higher efficiency than sand filters,” he noted.
