Hexcel Corporation (Hexcel) located in West Valley City, is a leading supplier of carbon fiber, honeycomb and other composite materials for the commercial aerospace industry. Our wastewater discharge consists of carbon fiber rinse water, reverse osmosis rejects water, cooling tower blowdown, and non-contact cooling water. The discharge from these sources is considered high-quality for wastewater.
In 1997, Hexcel began investigating the feasibility and regulatory requirements of reusing this water for irrigation. An agreement was reached with West Valley City, the Division of Water Quality, and the Canal Governing Board to discharge Hexcel’s high-quality wastewater to the West Valley City Municipal Golf Course. During the winter (non-irrigation) months, water would be discharged through the golf course’s existing lines to the Salt Lake Canal. The quality of the water would be monitored as prescribed in Hexcel’s Utah Pollution Discharge Elimination System (UPDES) permit. The UPDES permit includes limits for TDS, BOD5, TSS, and other parameters.
This best practice has been mutually advantageous to all participants; Hexcel, West Valley City, Central Valley Water Reclamation Facility (CVWRF), and Jordan Valley Water Conservancy District (JVWCD). An estimated 511 million gallons have been beneficially used to irrigate the West Valley Municipal Golf Course since implementation, based on an average flow rate from Hexcel to the golf course between 40,000 and 100,000 gallons per day, or approximately 26 million gallons per year.
