Water Treatment

UPI runs two onsite water treatment processes, the Filter Plant and the Reverse Osmosis (RO) Unit that treat the water prior to use. The Terminal Wastewater Treatment Plant (TWTP) cleans the waste water prior to discharge. We are proud to say that due to extensive Operator training, source control, Best Management Practices and acute testing, the water that UPI releases back to the river is cleaner than the water we initially took in! Additionally, UPI has consistently maintained an outstanding compliance record since the completion of our Modernization Program in the late 1980s.
