Water is one of the most significant challenges facing the agricultural sector in Iraq, necessitating the search for alternative water sources. Wastewater solutions have been reused in one of the additional sanitation facilities to alleviate pressure on freshwater resources. Water contains some nutrients, such as nickel and phosphorus, which can benefit plant growth. However, it is deficient in essential minerals, with the exception of selective salts and small and medium-sized microbial particles. Therefore, developing centralized treatment protocols and adhering to plastic and health standards contribute to ensuring water and agricultural sustainability and effective water resource management in Iraq.
