The US International Boundary and Water Commission (USIBWC) operates and maintains the Nogales International Wastewater Treatment Plant (NIWTP) in Rio Rico, Arizona. The NIWTP currently treats approximately 17 million gallons per day of raw sewage entering from Nogales, Mexico and Nogales, Arizona. The NIWTP was recently upgraded to provide Biological Nutrient Removal (BNR) resulting in a demand for supplemental carbon.

Technical Requirement is determined as conformance to the requirements of each CLIN and SOW. The non-cost evaluation factors for this requirement are: (1) Technical Requirement [see SOW #3] and (2) Past Performance.
