Qatar’s reuse of treated wastewater, notably for the irrigation of green spaces, made robust expansion year-on-year and garnered more share in the total wastewater reused this June; indicating the country’s strengthened sustainable development efforts.
The rising reuse of treated wastewater in the farming sector comes amidst more than 10mn kgs of local vegetables being procured during the current crop season. The country uses the most modern membrane ultra-filtration system that helps in the recycling of treated wastewater.
Qatar’s treated wastewater stood at 24.02mn cubic metres out of 24.13mn cubic metres of wastewater received in June this year, said the figures released by the Planning and Statistics Authority.
The treated wastewater saw a 9.47% year-on-year increase even as it shrank 4.5% month-on-month in June 2020.
The treated wastewater reused for irrigation of green spaces saw 18% and 28.5% surge year-on-year and month-on-month respectively to 8.92mn cubic metres, which accounted for 37% of total treated wastewater in June 2020 against 28% in the previous month of this year.
There has been a robust reuse of treated wastewater in agriculture, a sector whose prominence has been increasing as part of the self-sustaining initiatives, especially after the country came under unjust economic and trade embargo.
The treated wastewater reused in agriculture increased by 2.2% year-on-year to 7.49mn cubic metres, constituting more than 31% of the total treated wastewater this June (compared to more than 33% in May 2020). On a monthly basis, it plunged 10.7%.
The growth in the re-usage of treated wastewater for agriculture hints at the hydrocarbons-rich country’s Green initiatives, a key parameter of sustainability.
Hassad Food subsidiary Mahaseel for Marketing and Agri Services has undertaken various measures to improve and expand the output in the farm sector with its far-sighted marketing and other support measures.
The treated wastewater reused in deep injection into aquifers registered 1.1% yearly expansion to 6.07mn cubic metres or more than one-fourth of the total treated wastewater used in June 2020 compared to 28% a month ago. On a monthly basis, it fell by a sharp 13.9%.
The treated wastewater discharged into lagoons in May 2020 stood at 1.55mn cubic metres or 6% of the total treated wastewater reused against 11% in May 2020. Such discharge saw more than 55% increase year-on-year but fell 44.1% on monthly basis.
There was no discharge of treated wastewater into sea in June 2020.
The Water Centre at the Qatar Environment and Energy Research Institute, part of Hamad Bin Khalifa University, has been helping Qatar in tackling its water security challenges by conducting research, development and innovation to enhance every step of the water cycle in Qatar.
Multiple projects are currently underway at the Water Centre, including water treatment for agricultural irrigation in desert climates, development of physical filtration systems such as membranes and filters, brine management, ballast water, characterisation of the sub-surface and soils, and strategies for managed aquifer recharge.
