How your Best Practice is economically feasible ?
It brings a net benefit compared to buying freshwater for irrigationResult of this assessment
The water is reclaimed and would otherwise not be available at this site, the plant is economically highly feasible.Enviromental impact
SDGs
Validation/upscaling
No
Potentiel of exploitation/outscaling
There are 5000 hammams in Morocco, which could all have a similar greywater treatment. It could be implemented at all hammams wherever these are operated.
Lessons learnt
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…
Recommandations
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,…
