A sustainable management of the hydric deficit in Large Sousse (Tunisia): local solutions to reduce the interregional transport of water

Nadia Sahtout, Mohamed Taoufik Bouzidi, Noureddine Mzoughi

The city of Sousse and its suburbs is confronted with a strong human and socio-economic attraction, but paradoxically, this area is very underprivileged on the hydric level. The transport of water from the surplus areas’ water towards the overdrawn areas of Tunisia will not be able henceforth to constitute a durable solution because of a saturated network of adduction and distribution. A new vision of urban water management seeks to guide users towards a more rational behavior and to encourage the production of unconventional water.  We present in this article a test of quantification of the water produced and scenarios of demand evolution from a prospective analysis.
