“…The increase in the activity of some enzymes (e.g. hydrolytic, proteolytic, laccases, cellulases, phosphatase) has been reported in soils irrigated with treated wastewater (Adrover et al, 2012;Alguacil et al, 2012;Chevremont et al, 2013;Elifantz et al, 2011;Frenk et al, 2014;Friedel et al, 2000;Meli et al, 2002;Morugán-Coronado et al, 2013). It is, thus, suggested that wastewater irrigation may stimulate the activity of microorganisms involved in the biochemical balance of elements such as C, N and P. In addition, organic matter may stabilize the enzymes, which remain active in the ex-tracellular medium, independently of the soil microbial (Trasar-Cepeda et al, 2008a).…”

“…Examples are the activities of enzymes such as dehydrogenase, laccase, cellulase, protease and urease (Chevremont et al, 2013;Friedel et al, 2000;Liu and Haynes, 2011;Morugán-Coronado et al, 2013). These effects are probably due to the stimulation of microbial growth and activity, boosted by the organic matter and nutrients supplied by wastewater (Adrover et al, 2012;Chevremont et al, 2013;Friedel et al, 2000;Liu and Haynes, 2011;Morugán-Coronado et al, 2013;Tam, 1998).…”

“…One of the advantages of wastewater irrigation is the supplying of nutrients that may be sufficient to replace, or at least to reduce, the use of synthetic fertilizers in agriculture (Adrover et al, 2012;Fatta-Kassinos et al, 2011;Toze, 2006). The fertilizing potential of the wastewater (assuming an application rate of 5000 m 3 /ha year) can reach annual values as high as 250 kg/ha for N, 50 kg/ha for P and 150 kg/ha for K (Pescod, 1992).…”

The reuse of treated wastewater, in particular for irrigation, is an increasingly common practice, encouraged by governments and official entities worldwide. Irrigation with wastewater may have implications at two different levels: alter the physicochemical and microbiological properties of the soil and/or introduce and contribute to the accumulation of chemical and biological contaminants in soil. The first may affect soil productivity and fertility; the second may pose serious risks to the human and environmental health. The sustainable wastewater reuse in agriculture should prevent both types of effects, requiring a holistic and integrated risk assessment. In this article we critically review possible effects of irrigation with treated wastewater, with special emphasis on soil microbiota. The maintenance of a rich and diversified autochthonous soil microbiota and the use of treated wastewater with minimal levels of potential soil contaminants are proposed as sine qua non conditions to achieve a sustainable wastewater reuse for irrigation.

“…However, since the suitability of water for irrigation greatly depends on the climatic conditions, physical and chemical properties of the soil, the salt tolerance of the crop grown and the management practices ( [17]; further work will need to be carried out to establish the likely impact of the greywater generated on soils in the two areas. An evaluation of the chemical properties and biological activity in soils in the Mediterranean island of Mallorca following twenty years of treated wastewater irrigation revealed that the treatment did not have any negative effects on the measured soil parameters [33].…”

A Comparison of the Physico-Chemical and Bacteriological Quality of Greywater from Water Deficient Households in Homabay Town and Githurai Estates in Kenya

Greywater, the untreated household wastewater that has not been contaminated by toilet waste, has been touted as a reliable all year-round source of water, especially in water scarce areas. Although it is commonly reused in water scarce urban and peri-urban settlements in Kenya, information on its bacteriological and physico-chemical properties is generally limited. The present study sought to compare the physico-chemical and bacteriological quality of kitchen and laundry greywater from an urban (Githurai) and peri-urban settlement (Homabay). Compared to the source water, kitchen and laundry greywater at the two sites had higher electrical conductivity (EC) and salinity, depressed dissolved oxygen (DO) levels and a wide pH range. Although significant differences in EC, DO and salinity of greywater from kitchen and laundry were noted (P < 0.05), the two sites differed significantly only in DO (P = 0.002). Total coliforms (TC) and fecal coliforms (FC) were also higher in greywater than in source water. The greywater types differed in TC (P = 0.003) while the two sites differed in both TC and FC (P 0.03). High loads of TC and FC suggest possible fecal contamination of greywater. This coupled with the occasional presence of Salmonella, Shigella and Vibrio cholerae means that reuse of untreated greywater is not safe in both sites, and should be treated before use. Owing to the differences in the quality of the different types of greywater as well as the sites investigated, the design of greywater treatment technologies should consider both type and source.

“…Kayikcioglu ( 2012 ) detected a decrease in the microbial activities in soil, depending on irrigation with wastewater in Mediterranean countries. Adrover et al ( 2012 ) claimed that after more than 20 years of treated wastewater irrigation, no negative changes have been observed in the evaluated soil properties of the Island of Mallorca in Spain, with the exception of an increase in the soil pH caused by greater sodium supply. In China, Shi et al ( 2012 ) found that due to the spatial distribution of Fluoroquinolones (Fluoroquinolones are broad-spectrum antibiotics that play an important role in treatment of serious bacterial infections) in wastewater irrigation was a potential source of antibiotics.…”

Global Experiences on Wastewater Irrigation: Challenges and Prospects

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.
