“…As the world faces increasing freshwater scarcity, wastewater use is gaining attention as an option for augmenting available water supplies. Agriculture irrigation is by far the most established application of wastewater reuse in the world (Scheierling et al, 2011). Yet, agriculture still accounts for over 70 percent of the world's total freshwater withdrawal (FAO, 2012).…”

“…Wastewater supplementation could increase profi ts by $20 million annually; alternatively, wastewater replacement could conserve 35 Mm 3 of water in local rivers each year in China (Murray and Ray 2010 ). Scheierling et al ( 2011 ) deduced that achieving safe wastewater irrigation required steady progress over several decades. In Europe, treatment requirements for restricted and unrestricted irrigation would be identical, that means treatment cost for unrestricted irrigation is lower and thus this treatment level is more probable to be feasible and practicable.…”

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.

“…There is thus no guarantee that the wastewater disposed into the WSPs is purely from the domestic uses. Industrial wastewater is a source of toxic substances or biological process inhibitors (Chove et al, 2006;Jiménez, 2006;Scheierling et al, 2011). Once discharged into the WSPs, it deters the efficiency of the ponds.…”

Obstacles to Low Quality Water Irrigation of Food Crops in Morogoro, Tanzania

Knowledge on users' and regulators' views regarding obstacles on the use of low quality water forms the basis for the improvement of water reuse in food crops irrigation. A qualitative study was conducted to assess the obstacles to the use of low quality water for irrigation of food crops in urban and peri-urban areas in Tanzania. The study considered Morogoro urban and peri-urban areas as a case study due to the existence of paddy and vegetable production using the effluent from the waste stabilisation ponds. Both primary and secondary data were used. Primary data were collected through in-depth interviews with 22 key informants, and 4 focus group discussions with farmers. Content analysis was used in this study. Findings show that domestic wastewater was poorly disposed, waste stabilisation ponds as treatment facilities had limited management, and quality monitoring of effluent from the waste stabilisation ponds was limited to permit safe use of the effluent in food crops irrigation. The government officials were of the view that the effluent from the waste stabilisation ponds should not be used for leafy vegetables irrigation while farmers viewed vegetables farming as a quick source of income and livelihood strategy for many years. The study therefore suggests that the relevant agencies should improve the treatment of wastewater and quality monitoring of the effluent for safe use of low quality water for food crops irrigation in urban and peri-urban areas.
