“…Studies examining indirect effects of various TWE qualities (CHOUDHARY et al, 2006;MINHAS et al, 2007;TEDESCHI and DELL' AQUILA, 2005; VAN HOORN et al, 2001) are also generally based on short-term laboratory experiments, sometime using continuous water flow in packed soil columns (JALALI et al, 2008;SUAREZ et al, 2006). In the present study, the impact of the TWE irrigation on soil properties was studied under normal cropping conditions.…”

“…Most of the salts added are only partially removed during conventional sewage treatment (secondary and tertiary), so they remain in the irrigation water (TARCHITZKY et al, 1999). Previous studies related to the changes in soil salinity and sodicity after irrigation with wastewater are mostly based on short-term laboratory experiments with continuous water flow in packed soil columns (JALALI et al, 2008) or on controlled field experiments conducted in small plots HERPIN et al 2007;HULUGALLE et al, 2006). However, little is known about the time needed for soil salinization to appear in real agricultural conditions.…”

In arid regions such as near Sfax (Tunisia), treated wastewater effluents (TWE) are often applied as agricultural irrigation. Irrigation TWE usually contain large amounts of carbon, nitrogen and sodium. The objective of this study was to evaluate the impact of TWE irrigation on soil salinity and sodicity. In the city of Sfax, two sites were selected with two soil types (fluvisol and calcisol) having been irrigated for 4 and 15 years respectively. Soils were sampled at three different depths (0-30, 30-60 and 60-90 cm) in the TWE irrigated area and in a non-irrigated control area. Irrigated and non-irrigated study soils were analyzed for pH, nitrate and ammonia, electrical conductivity (ECs), exchangeable sodium percentage (ESP), sodium absorption ratio (SAR) and soil organic matter.The fluvisol, irrigated for only four years, is more affected by salinity than the calcisol irrigated for 15 years. In the upper fluvisol layer irrigated by the treated wastewater, ECs reach 8 mS•cm-1 and ESP a value of 15% while in all layers of the calcisol, ECs and ESP are lower and rarely exceed 4 mS•cm-1 and 6% respectively. This result is due to a combination of factors in the fluvisol treatment area including texture, cation exchange capacity, irrigation procedure and crop management.Dans les régions arides telles que le cas de Sfax (Tunisie), les eaux usées traitées (EUT) sont souvent utilisées en irrigation agricole. Généralement, les EUT sont riches en composés organiques, en azote et en sodium. L’objectif de cette étude est d’évaluer l’impact de l’irrigation par les EUT sur la salinité et la sodicité des sols. Dans la région de Sfax, deux sites ont été sélectionnés, représentant deux types de sols différents (fluvisol et calcisol) irrigués par les EUT, respectivement depuis 4 et 15 ans. Des échantillons des sols ont été prélevés systématiquement à trois profondeurs différentes (0-30, 30-60 et 60-90 cm) au niveau des parcelles irriguées et sur des placettes contrôle non irriguées (témoin). Sur chaque échantillon composite de sol, les pH (eau, KCl), teneurs en nitrate et ammonium, capacité d’échange cationique (CEC), conductivités électriques (CEs), taux de sodium échangeable (ESP), ratios d’absorption de sodium et teneurs en matières organiques ont été mesurés.Le fluvisol, irrigué depuis seulement quatre ans, est plus affecté par la salinité que le calcisol, irrigué depuis 15 ans. Dans les niveaux de surface du fluvisol, la CEs et l’ESP ont atteint les seuils critiques de 8 mS•cm-1 et 15 % respectivement, alors qu’au niveau du calcisol, la CEs et l’ESP sont plus faibles et dépassent rarement 4 mS•cm-1 et 5 % respectivement. Pour le fluvisol, ce résultat est dû à la combinaison de plusieurs facteurs impliquant la texture, la capacité d’échange cationique, la procédure d’irrigation et la rotation des cultures

“…This initiated the development of guidelines for the management of wastewater and solid waste at wineries (Van Schoor, 2005). A shortage of good-quality water leads to an increasing demand to irrigate with poor-quality water such as saline groundwater, drainage water and treated wastewater (Jalali et al, 2008). The negative effects of re-using untreated municipal and other industrial wastewater for agricultural irrigation are well documented (Bond, 1998;Papini, 2000;Mulidzi, 2001;Arienzo et al, 2009;Christen et al, 2010;Laurenson et al, 2012;Laurenson & Houlbrooke, 2011;Mosse et al, 2011;Arienzo et al, 2012).…”

The wine industry needs solutions for wastewater treatment, as environmental legislation for its disposal is increasingly being enforced due to non-compliance. The feasibility of re-using diluted winery wastewater was assessed in a pot experiment under a rain shelter over four simulated irrigation seasons. Four soils varying in parent material and clay content, viz. aeolic sand from Lutzville containing 0.4% clay, alluvial sand from Rawsonville containing 3.3% clay, granite-derived soil from Stellenbosch containing 13% clay, and shale-derived soil from Stellenbosch containing 20% clay, were irrigated with wastewater diluted to 3 000 mg/L COD (chemical oxygen demand), whereas the control received municipal water. Irrigation with diluted winery wastewater increased the pH (KCl) in the shale-and granite-derived soils into the optimum range for P availability. Although pH (KCl) in the aeolic sand was initially above the optimum range, relatively high Na + levels also caused available P to increase as the pH (KCl) increased. The pH (KCl) in the alluvial sand increased beyond the optimum range, thereby causing a reduction in the available P. This indicates that irrigation with diluted winery wastewater may only enhance P absorption if the pH (KCl) shift is towards the optimum. It must be noted that the results represent a worst-case scenario, i.e. in the absence of rainfall or crops.

“…High hardness and linearity among major ionic species in groundwater indicate the dissolution and mixing processes along the groundwater fl ow path (Chen et al 2006 ). Jalali et al ( 2008 ) showed in Iran that if wastewater was applied to soil for a long enough period, leaching concentrations will reach groundwater at elevated levels. Wu and Cao ( 2010 ) informed that concentrations of metals in groundwater from wells were lower than the China Groundwater Quality Standard and the WHO guideline values for drinking water, but a substantial build up of Hg and Cd in river sediments and wastewater-irrigated soils was observed.…”

“…Although heavy metals-containing wastewater irrigation ceased more than 10 years ago, the soil in the Zhangshi Wastewater Irrigation Area in China is still heavily polluted by Cd and to a lesser degree by Zn and Cu, in light of the China Environmental Quality Standards (Zhang et al 2008 ). In Iran, Jalali et al ( 2008 ) determined that the average exchangeable sodium percentage (ESP) of soils increased during leaching from 9 to 21 and 28.8-29.7 after applying 5.0 and 3.5 L (about 7 and 6 pore volumes) of wastewater to the soils columns, respectively. Lado and Ben-Hur ( 2009 ) showed in Israel that leaching of loamy and clay soils with effl uent that contained high concentrations of suspended solids led to a signifi cant reduction in hydraulic conductivity, caused by trapping of more suspended solids in the large numbers of small pores in the soils.…”

The need for irrigated agriculture is growing day by day and the largest water withdrawals from renewable water resources are for irrigation. In addition, the available water resources are decreasing and we need to use non-conventional water resources for irrigation due to looming water crisis (Raschid-Sally and Jayakody, Drivers and characteristics of wastewater agriculture in developing countries: results from a global assessment. International Water Management Institute, Colombo, 35p, (IWMI Research Report 127), 2008). However, the volume of treating and using wastewater is limited due to the lack of adequate data and knowledge and/or negative effects of improper wastewater management (i.e. use of untreated wastewater). A comprehensive evaluation of what has been done is necessary in order to explore wastewater irrigation and to avoid trial-and-error policies. Although a study of wastewater irrigation from crops, soil, groundwater, health, irrigation equipments, modern technologies, and other environmental aspects is useful, management studies in comparison with other aspects can help lead to more reliable and more extensive fi ndings and fi nally a better decision on using wastewater for irrigation. The chapter presents challenges and prospects that may help decision making for the use of wastewater in irrigation.
