Abstract: Due to the lack of water around the arid areas, potable water luxurious uses - are increasingly contested. In order to solve this problem, non conventional water resources, like treated wastewater, gained increasing role in the planning and development of additional water supplies in irrigated areas. Hence, wastewater recycling should be more implemented, especially in arid and semiarid regions, where the water shortage is an important limiting factor for the economy, in order to avoid drastic measures of consumers selection. In most cases, the intense use of effluent for irrigation attracted public awareness in respect of contaminating pathogens, heavy metals, salts and other chemicals. For safe wastewater reuse in irrigation is generally used the tertiary effluent, without advanced treatments (like membrane technologies) due to their high costs. Therefore, wastewater will conserve its salinity, contaminating irrigated soils and decreasing plant growth. The objective of this work is to present techniques used to control soil salinity, according to the sustainability of the soil and water conservation in arid irrigated areas. These techniques include the conventional techniques (leaching, salts plus fertilizers combination and the use of salt tolerant crops) and environmentally safe and clean procedures (salt removing species, drought tolerant crops and visual appearance). Results of the application of these techniques are presented. It may be seen that clean procedures may be not enough to solve the salinity problems. Hence, it is concluded that the clean and environmental safe procedures salinity could be associated to the conventional techniques, combining environmental, economical and social aspects, contributing, therefore, to increase the sustainability of irrigated areas and plant growth.
