In this study, we present the results of scenarios where secondary‐treated municipal wastewater was used for table grapes irrigation in the region of Ablah, Bekaa valley in Lebanon, and fodder crops irrigation (vetch and barley) in the region of Ramtha in Jordan. In Lebanon, we carried out experiments to assess the response of drip‐irrigated table grapes grown under two water quality regimes (Freshwater (FW) and treated wastewater (TW) and two water levels (100% of evapotranspiration (ETc) and 75% of ETc). While in Jordan, we carried out experiments to assess the response of drip‐irrigated fodder crops considering 4 irrigation levels (Q1: Rain fed; Q2: 80% of ETc; Q3: 100% of ETc; Q4: 120% of ETc) and three crop patterns (C1: Barley 100%; C2: Vetch 100%; C3: Mix 50% barley and 50% vetch). Based on the production and quality components, table grapes were successfully grown on plots that are supplied with TW. Fodder crops were successfully grown using TW with remarkable increase in biomass and grain yield production for the irrigated treatments.

A study was conducted in the Bekaa valley of Lebanon aiming to produce spinach leaves with treated effluent from Joub Janine plant under two growing seasons. Two experiments were laid out in a randomized complete block design. The effect of water quality on the qualitative, quantitative aspects and microbiological contamination of leaves was assessed. The results showed that the treated wastewater from Joub Janine plant was of category III. The highest mean marketable yields was recorded for T7 (4727 g•m −2 ) followed by T6 (3533 g•m −2 ) that were drip irrigated with treated wastewater. The uptake of K, Mg, Na and Cl was significantly 49.09%, 30.20%, 96.79% and 33.20%, respectively, higher in the spring than in autumn. The nitrate levels in all treatments and seasons were below the maximum level in foodstuffs as provided by the European Commission regulations. For the lipophilic fraction, there was no significant difference among treatments and also among treatments and seasons interacting together and the highest hydrophilic fraction and total phenols levels recorded for the autumn rather than the summer season. In general, pathogenic bacteria was absent on spinach leaves for all treatments and growing seasons.
