Downtown Doha to save 6.5m litres of water per day
The Msheireb project to take advantage of a non-potable water system
Msheireb Properties has announced a site-wide non-potable water system within Downtown Doha, which will reduce water consumption by up to 6.5 million litres per day
Thewater system will treat municipality supplied Treated Sewage Effluent (TSE) so it is pure enough to be used in the district cooling system, which utilises energy efficient evaporative chillers, and also for irrigation of the site's vegetation and for the flushing of all toilets.
This will save over 6,500,000 litres of potable water per day.
"We conducted thorough research into various alternative solutions in terms of setting the highest benchmark for water conservation and treatment," said Mohammed Al Marri, director - projects, Msheireb Properties.
A drip irrigation system and a planting scheme that focuses on native and adapted species will be done to ensure an efficient irrigation system. This will reduce evaporative losses and the landscaping will require less water overall.
The system will earn water efficiency credits under LEED, which recognises the use of non-potable water. The project will also receive further LEED Points for water efficient fixtures which will reduce potable water consumption up to 30%.
To promote water conservation, Msheireb Properties will also select fixtures across the project for their efficiency. Potable water supply and consumption will be carefully monitored for leaks in the system or over-consumptions.
"I am confident that we have in place the best possible solution which will support the project's sustainability agenda and meet the needs of residents," added Al Marri.
