Abstract

This study was carried out to determine the suitability of effluents from the University of Nigeria, Nsukka (UNN) sewage treatment facility for irrigation purposes. The result shows that, from the point of view of ECw, SAR, solids, organic matter content, ion toxicity and nutrients (except Phosphate), the UNN wastewater treatment plant effluent can be safely used for irrigation, especially under short term. Although the fecal coliform load is within the value allowed for irrigation water, it is recommended that irrigation must cease at least two weeks before the crop is harvested to avoid any form of contamination. The effluent quality of the sewage plant also substantially met the effluent quality standards of Nigeria and other countries.
