“…It is found in the literature that even elevations in EC are observed in vertical CWs. Gross et al (2007) found an increase of 8% and Morari and Giardini (2009) observed a 37% increase in the EC of the CW effluent.…”

In this study, the role of Cyperus sp. was evaluated for removal of pollutants from swine wastewater. Vertical-flow pilot scale constructed wetlands (CWs) operating with a hydraulic retention time (HRT) of 72 h were monitored in a greenhouse, located in Viçosa, Brazil. Significant differences were observed for the following parameters: Kjeldahl nitrogen, total phosphorus, alkalinity and electric conductivity, with averages removals of 37.5 and 28.5%, 55.9 and 44.4%, 30.2 and 25.6 and 26.1% and 22.9% (for planted and unplanted CWs, respectively). The rate of dry matter yield from Cyperus sp. was 7.5 gm −2 day −1 , and the nutrient uptake capacities were 21.8, 2.1, 14.0 and 0.9 gm −2 of N, P, K and Na, respectively. Evapotranspiration (2.7 mm day −1 ) was statistically higher in the planted CWs. Plants in the CWs are important for achieving high nutrient removal.

“…The nitrified anaerobic effluent is used as both fertiliser and irrigation water. Morari and Giardini (2009) assessed the treatment efficiency of pilot-scale vertical-flow constructed wetlands on municipal wastewaters and their suitability for irrigation reuse in Italy. Only water quality parameters with high removal efficiencies fulfilled the Italian guidelines for irrigation reuse, whereas parameters with lower efficiencies such as suspended solids and total phosphorus limited the potential water reuse.…”

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.
