Tunisia has made considerable efforts to solve major environmental problems. Reforestation of vast marginal spaces with appropriate species, such as poplar, is one of the economic and environmental challenges (I-488). The fast-growingof this rupicolous species has a high specific versatility in its use. However, its need for water will limit their use in reforestation in areas where water resources are scarce. To cope with this situation, the use of unconventional water resources, including wastewater treatment, is a promising way to increase domestic production of wood. Thus, the treated wastewater is valued as a source of unquestionable water, but also as a source of nutrients. These plants were raised under non-binding for four months and divided into two lots irrigated daily to field capacity with (i) potable water (control : T) and (ii) with treated waste water (TWW). Biomass production, gas exchange and some mineral ions were measured during the experiment, in summer. Our results indicate that irrigation with treated wastewater has submitted a substantially marked effect resulting in an increase of gas exchange. Furthermore, after 60 days, the accumulation of certain metal ions (Cd, Pb and Ni) has resulted in a major malfunction on gas exchange.
