This intervention site is located in the region of Ariana in the northeast of Tunisia.  

In the area, there are no conventional water resources both surface and groundwater. The Waste Water Treatment Plant (WWTP) is used to treat urban effluent and Treated Wastewater (TWW) is mainly used to irrigate public parks.

👉Choutrana II has been selected as a representative learning site for demonstrations and scientific research targeting researchers, farmers, NGOs, etc. In the site, water quality has been improved by installing a tertiary treatment system to enable the diversification of crops, and the implementation of low pressure irrigation systems  tailored for TWW for a better distribution efficiency and reliability of the material.
