“…Sodicity is caused by expansive and dispersive processes on clays as a consequence of the destruction of aggregates due to high Na + concentrations [109,110]. Different research studies noted that changes in sodicity generate an increase in soil compaction and reduce the infiltration rate of water [108,109,111].…”

Wastewater Reuse in Agriculture: A Review about Its Limitations and Benefits

For centuries, wastewater has been improperly used in agriculture, presenting potential risks to public health and the environment. In the context of scientific development, and confronted by an increasing water crisis, wastewater reuse merits consideration because the practice helps decrease water use pressure and moderates water pollution. Thus, this article presents a literature review that addresses the effects, both positive and negative, of wastewater use in agriculture, emphasizing the effects on the soil environment. The literature review reveals that, until the 1990s, research studies promoted the use of wastewater for irrigation purposes from a treatment approach, while proposing "end of pipe" conventional solutions. However, more recent research studies (2012)(2013)(2014)(2015)(2016) reveal that agricultural reuse significantly affects soil texture properties, while also causing possible alterations of the biomass and microbiota. In addition, research in this period has been oriented to the quantitative evaluation of microbiological risk.

“…• Irrigation with GW containing food matter, grease, and surfactants may create hydrophobic soils that prevent soil infiltration, cause odors, and attract vectors (Gross et al 2005;Morel and Diener 2006;Travis et al 2010;Dalahmeh et al 2011). …”

Support for the use of treated gray water as an alternative water resource in the Middle East and North Africa is high, especially given the lack of religious restrictions against its use, but several obstacles have kept application of treated gray water near 1 % in some areas. The largest of obstacles include the cost of treatment and the ambiguity surrounding the health safety of gray water and treated gray water. This paper aims to provide an overview of current gray water practices globally, with specific focus on household-level gray water practices in the Middle East and North Africa region, and highlight the need for cost reduction strategies and epidemiological evidence on the use of household-level gray water and treated gray water. Such actions are likely to increase the application of treated gray water in water-deprived areas of the Middle East and North Africa.

“…One commonly applied individual initiative to reuse wastewater is the recycling of greywater specifically for irrigation (Travis et al, 2010). In fact, in the past years greywater reuse for irrigation has been considered as a mean of water conservation, since represents the largest potential source of water and costs savings in domestic residence (Al-Jayyousi, 2003), savings up to 38% of water when combined with sensible garden design.…”
