The Msheireb Downtown Doha project will re-use non-potable water for many purposes across the development, saving millions of litres of water a day, says this report from the Qatar News Agency.

The project – which claims on its website to be the world’s first sustainable city centre regeneration project – will treat sewage so that it is clean enough for use in district cooling, plant watering and the flushing of toilets.

The announcement is timely, given Qatar’s unfortunate placing as the world’s highest user of water per capita – 430 litres per person, per day. 

What do you think? Should non-potable water be used more widely in Qatar?
