- commonly adopted definition of resilience
the quality of a system of being able to resume its original shape, or to recover quickly, in particular after an accident
Derived from Latin, resilire had evolved, from stepping forward to jumping backward, once or several times
- opposite meanings in French and English
in French : resilire gave the verb résilier, = to terminate
in English : resiliency stands for the ability to cope with changes
continuity in the life of a city and its functionalities
Definition of Urban Resilience
- drainage
Action of removal of surface and sub-surface water from an area
Major Components of
Urban Water Systems in Paris
- sanitation
Action of collecting human excreta (later wastewater), along with its transportation, treatment and disposal/reuse
- drinking water supply
Action of catching, transporting (later treating) fresh water for human consumption

Conclusions
Urban water systems of the
Metropole of Paris have evolved
in technical and spatial
directions through centuries
There is no long term resilience
Is onsite sanitation the future ?
