Following the agronomic characterization & irrigation appraisal, soil analysis and modelling have been carried out to estimate the water requirements and potential impact of TWW re-use on the soil quality, and then to design and implement innovative irrigation scheme to increase efficiency and productivity. Study on soil-water fluxes have also been performed by Al Najah university and CIHEAM BARI to predict deep percolation of TWW. 

After consulting and collaborating with Ministry of Agriculture (Nablus directorate), WW-GVC was advised about the water requirement needed for each type of crops. CIHEAM BARI then modelled and calculated for each plot the amount of TWW needed using meteorological data, soil characteristics, crop type and number of plants. Based on these results and the WWTP effluent quality, the irrigation network was designed (more than 5 km of pipelines), water allocation to each farmer determined and proper irrigation management practices recommended for grape, lemon, olives and alfalfa respectively. The action targeted 14 farmers and 7.6 hectares.

Constant trainings and workshops addressed to farmers and village council's representatives have been carried out on optimal water management and sustainable agricultural practices. Finally, guidelines on safe reuse of TWW in agriculture, monitoring and maintenance have been shared among farmers.
