Deteriorating quality and increasing scarcity of water in Iraq demands a rethink in the way wastewater is managed. We show here that a constructed wetland can assist an existing sewage treatment plan not only to be lower than actual Iraqi effluent standards, but to also meet water quality criteria for reuse in agricultural production.
Scarcity is one of several challenges to the Iraqi waters. The increasing demand from both drinking water and agriculture is overshadowed by uncertainties related to further dam construction in upstream countries. The overall aim of this study is to establish if a constructed wetland built on the available land would be sufficient to reduce the effect of wastewater effluents on the Euphrates, and meet the more stringent standards of water reuse for agriculture.
