“…Use of wastewater in agriculture helps to recycle useful nutrients in the soil. However, this practice, in particular, can lead to serious health consequences for farmers and consumers as well, because the broad spectrum of pathogenic organisms, toxic chemicals and heavy metals in the wastewater is transferred to food chain via consumption of sewage irrigated crops [4].…”

“…Domestic wastewater contains high amount of nutrients essential for crop development compared to fresh water which might decrease the dependency on chemical fertilizers and can also reduce the discharge into water bodies (Urbano et al 2017). However, many negative impacts have been found to be associated with application of untreated wastewater such as deterioration of soil quality, reduction in crop yield, and heavy metals (HMs) pollution (Mukherjee et al 2013;Becerra-Castro et al 2015).…”

In this work, a pot experiment was conducted to evaluate the effect of organic amendments in alleviation of toxicity of untreated domestic wastewater to okra (Abelmoschus esculentus) and purslane (Portulaca oleracea). Three organic amendments including farm yard manure (FYM), poultry manure (PM) and bagasse ash (BGA) at the rate of 1% and 3% were applied to the soil to evaluate their positive impact on vegetable plants. Results showed that untreated wastewater impeded the growth of both vegetables and increased uptake of heavy metals (HMs) (i.e. Cu, Ni, Pb and Zn) by plants whereas organic amendments significantly improved the growth of plants and decreased the uptake of HMs. Shoot and root lengths and dry weights of plants were boosted by the FYM and PM, while chlorophyll a and b and carotenoids were enhanced by PM and BGA amendments. Interestingly, reduced HMs uptake was found where 3% of BGA or FYM were applied. Overall the results of this study showed that all three organic amendments were useful for improving growth of vegetables and alleviating the phytotoxicity of untreated wastewater and uptake of HMs by plants. Our findings suggest that these organic materials could be useful for improving agricultural productivity in untreated wastewater irrigated areas.

“…Irrigated rice cultivation makes up 55% of harvested rice area and contributes to 75% of global rice production [19]. Irrigation of rice paddy using treated or untreated wastewater is extensively practiced and examined in many countries to investigate benefits [20][21][22][23][24][25][26] or drawbacks of the practices [12,[27][28][29][30][31][32][33].…”

Current Perspective on Irrigation and Drainage

View full text Add to dashboard Cite

In scene of worrisome water shortage, municipal wastewater has been gradually accepted as an alternative water resource containing important nutrients for irrigation. Rice cultivation, which is one of the main crops feeding global population and requires plenty of water for its effective growth, has been often irrigated by municipal wastewater in many countries. While irrigation of municipal wastewater for rice cultivation must bring benefits for farmers mainly by increased yield with less amount of fertilizers, it also has potential to cause drawbacks to human health and the environment. This chapter discusses about these aspects based on scientific works and practical experiences of municipal wastewater irrigation for rice production as well as the introduction of our concept to cultivate rice for animal feeding with irrigation of treated wastewater, which can contribute to resource circulation between urban and rural areas. The feasibility study under this concept has demonstrated that the target value of rice yield can be achieved and protein-rich rice preferable for animal feed can be harvested with irrigation of properly treated municipal wastewater.
