A model of land suitability analysis for irrigation with treated domestic wastewater is presented. The model integrates tools of Multi-Criteria Evaluation combined with Geographical Information System. Several criterions were selected and considered in the model with a prior adaptation to the conditions and characteristics of the particular case study. The adaptation process was made through field visits, bibliographical review and personal interviews with local actors and experts. Six constraints and ten factors were selected and 3200 hectares suitable for the activity were identified. The areas were classified into three categories of aptitude, presenting high fitness sites close to the current wastewater treatment plant. The developed tool allowed integrating different criteria for the assessment of the suitability of sites in the use of wastewater and can be modified for application in other regions and/or with other objectives.
