Phoenix, Arizona, January 20, 2000 - ON Semiconductor, formerly a division of Motorola, was honored today for developing a water conservation system that saves approximately 50 million gallons of water annually at the company's semiconductor manufacturing facilities in Phoenix. During a ceremony at ON Semiconductor's headquarters, President Steve Hanson accepted the Water Conservation award from Carol Erwin, Phoenix Area Office Manager, U.S. Bureau of Reclamation.

"As the demand for semiconductors continues to grow in the years ahead, water conservation efforts will become even more important for all of us," Hanson said. "We are proud to have our conservation efforts recognized, and we are pleased to have developed a system to demonstrate that wastewater can indeed be reused in the fabrication process."

The water conservation system includes a special drain system to collect rinse water (used in the manufacturing process) while allowing chemical wastes to pass through the existing waste treatment system. The collected rinse water is treated to remove various chemical impurities and is then used in the company's air pollution control systems. The chemical impurities are disposed of in an environmentally acceptable manner.

"Conservation efforts such as those made by ON Semiconductor should be recognized and encouraged," said Erwin. "Implementation of a wastewater reuse system supports and benefits our community by helping to guarantee the availability of future water supplies."

ON Semiconductor was nominated for the award by representatives of the City of Phoenix Water Services Department.

"The wastewater reuse process developed by ON Semiconductor will be of great benefit to our community and to other communities where semiconductor fabrication facilities are located," said George Britton, deputy manager for the city of Phoenix. "The metro Phoenix area is growing very rapidly. Innovative developments such as this wastewater reuse system are a crucial component of our effort to conserve resources and balance the demands of our residents and the companies that serve our communities. The water saved by this process is enough to supply more than 150 families of five for an entire year."
