How your Best Practice is economically feasible ?
It brings a net benefit compared to buying freshwater for irrigation
Is your Best Practice economically viable ?
10
Is your Best Practice environmentally sustainable ?
10
If there was a sustainability assessment carried out, what are the result of this assessment ?
The water is reclaimed and would otherwise not be available at this site, the plant is economically highly feasible.
Please indicate the other various social impact of your Best Practice :
Preservation of living environment, Improvment of health conditions
To which Sustainable Development Goals (SDGs) your Best Practice contributes?
SDG3: Good Health and Well-being, SDG6: Clean Water and Sanitation, SDG11: Sustainable Cities and Communities, SDG12: Responsible Consumption and Production
The pilot system worked satisfactorily, it provided NC water for green areas that would not have been avialable otherwise, but it was terminated for political/personal reasons 4 years after its start. Such innovations need a broad approach and long term support in operation, maintenance, etc.
Have you any recommendation to add?
To the water reclamation at the hammam a solar heater was added, that provided half of the required energy for water heating. Such systems could be implemented at all hammams throughout the region, if a respective policy and the necessary means, in terms of design, training and operation and maintenance skills were put in place.
