A model of land suitability analysis for irrigation with treated domestic wastewater ispresented. The model integrates tools of Multi-Criteria Evaluation with GeographicalInformation System. Several criterions were selected in the model to adapt to theconditions and characteristics of the particular case study. The adaptation processincluded field visits, bibliographical review and personal interviews with local actorsand experts. Six constraints and ten factors were selected and 3158 hectares suitable forthe activity were identified. The areas were classified into three categories of aptitude,representing high fitness sites close to the current wastewater treatment plant. Thedeveloped tool allowed the integration different criteria for the assessment of thesuitability of sites in the use of wastewater and can be modified for application in otherregions and/or with other objectives.
