Water availabity
End-of-studies project & thesis
How can we optimize capture and use of non-conventional waters in order to preserve drinking water for priority uses?
To tackle this issue, I did intensive research and contacted local experts about the lack of use of non-drinkable water in France.
This project is a demonstrator to show that we don’t have to use drinking water in for all purposes, and that non-conventional water ressources such as wastewater reuse and rainwater have great potential.
The goal is also to raise awareness in the public space by communicating on the challenges of water availability.
Work in progress: this graphic design aspect is under developement.
Concept
The concept features a road cleaning service where the dirty water is pumped back, treated and reused.
The system operates in a sustainable cycle separate from the city’s drinking water network, with rainwater harvesting at the beginning and reclaimed wastewater and extracted pollution at the end.
Pre-treatment in vehicules
This new system consists of electric vehicles carrying rainwater to clean the streets. They are cleaned with a high pressure water tool, studied to avoid splashes, any contact with the public or the operator, and draws back the dirty water into the truck.
The vehicules are equipped with a pre-treatment system that filters out the heaviest waste and hydrocarbons.
This way the water is reused in a loop for each cleaning. No need to refill the truck: it is never empty.
At the end of the day, the operator will empty the water into the nearest end-of-treatment unit:
they will finalize the sanitation of the used water.
End-of-treatment units
Once the wastewater is transferred to the module by the operator, the treatment starts.
It consists in separating the remaining pollution by a coagulation-flocculation technique.
The organic residue is separated from the water, leaving it clean enough to be reused for watering green spaces.
The organic sludge can be collected and recycled as compost.
