Intel Corporation
Reducing and Reusing Water at Chip Fabrication Plants
 


Hudson, Massachusetts

Expansion at the facility was limited by the capacity of the local publicly owned wastewater treatment works' (POTW) ability to limit phosphorus discharge into the Assabet River. By installing a state-of-the-art water management facility that increases water recycling and water reclamation, Intel will be able to boost production by more than 50% without increasing current discharge levels to the POTW. The new system will also collect and recycle 90% of the phosphorus from its manufacturing wastewater. Intel also donated $250,000 to the town's wastewater treatment plant to help it meet tighter state and federal limits.


Albuquerque, New Mexico

Depletion of groundwater reserves in Albuquerque's primary aquifer has created strong pressures for businesses to minimize water use. By installing a high-recovery reverse osmosis water purification process, improving chip washing and rinsing techniques, and using water-efficient landscaping, the Intel facility has reduced water use by 47 percent since 1994. Intel also reuses water from semiconductor rinsing in other industrial processes. In addition, the company pretreats wastewater and returns it directly to the city treatment facility. Seventy five to eighty five percent of all water Intel uses in manufacturing at this facility is eventually returned to the Rio Grande River.
