York International Corporation manufactures Heating Ventilation and Air Conditioner, HVAC, units for commercial and industrial applications. Production includes two (2) basic processes, fabrication and assembly. Fabrication includes cutting, forming, bending, brazing, and painting raw materials into finished components and parts. The finished components and parts are then assembled, using additional purchased components, to form a finished product for sale.
The cooling water used in the brazing process was initially set up as a once-through use. In about May of 2005 the system was modified to recycle the water used at each table until such time as it became too dirty for reuse, about two (2) weeks. Once the water has become too contaminated for reuse it is discharged to a portable tank and hauled to the wastewater treatment system and introduced into the facility's categorical wastestream.

Additional Information :
Although water use records for the brazing tables prior to and after the modification are limited, it is estimated that an average of approximately 15,000 gallons of water are saved each month.
