Iowa Fertilizer Plant

Our project team at the Iowa Fertilizer Plant project, situated in Wever, Iowa, successfully erected one of the world’s largest nitrogen-based fertilizer plants, ranking among the top five upon completion. Notably, this production facility stands as one of the pioneering natural gas-based fertilizer plants built in the United States in nearly three decades.

The scope of this project demanded precise execution, with process requirements encompassing 2,420 metric tons per day (mtpd) of ammonia, 2,200 mtpd of urea, 4,300 mtpd of UAN (urea ammonium nitrate), and 900 mtpd of DEF (diesel exhaust fluid). As an integral component of this critical infrastructure initiative, Weitz undertook the design and construction of a state-of-the-art 9 million gallons per day (mgd) water treatment plant. This facility ensures that raw water is processed to standards surpassing municipal regulations, guaranteeing the highest quality output. Additionally, on-site water treatment procedures are in place to address disposal concerns beyond property lines.

Through the production of both liquid and ammonia fertilizer, the plant boasts an impressive capacity of 7 million tons, facilitating distribution across all five major continents. Our steadfast commitment to excellence and innovation resonates throughout our large-scale projects, manifesting in every aspect of our endeavors.
