Sentry Equipment – Saving Water

In 2006 as Sentry was preparing for a move to a new building, they were notified by Oconomowoc Utilities of a $75,915 impact fee tied to their water usage.  The utility indicated that they were using 1,440,000 million gallons per year at their existing facility.  Investigation into the major water uses in the facility identified two large water-cooled compressors on their factory floor that used water at the rate of 4 gallons a minute 20 hours a day for 260 days a year.  These were replaced with air-cooled compressors in the new facility.
