INTRODUCTION – THE GROWING PROBLEM Globally, farmers are being pushed to utilize untreated or partially treated sewage water for irrigation, especially in low and middle-income countries. ·        According to UN estimates, 1.8 billion people  will experience water scarcity by 2050. ·        Globally, over 20 million hectares of farmland —an area roughly the size of Great Britain—are irrigated with untreated or partially treated wastewater. ·        That represents 10 % of all irrigated land worldwide.
