Full Description

With ongoing technical and financial support provided by Seattle Public Utilities, theUniversity of Washington has undertaken an aggressive and highly successful waterconservation program. Since peaking in the year 2000 at over 2 MGD, waterconsumption for UW facilities in Seattle has now been reduced by over 20%. This hasresulted in savings to UW of over $1.5 million per year at 2004 rates. As additionalmeasures are completed over the next two years, water consumption is projected to dropan additional 10%.Primary water conservation measures implemented by UW include cooling towerupgrades, conversion of water cooled refrigeration units to air cooled, leak and failedequipment repair, installation of waterless urinals, installation of low flow toilets,replacement of water cooled vacuum pumps with air cooled units, irrigation upgrades,installation of water efficient clothes washers, and upgrades to steam sterilizers and stills.Of all of these measures, excluding repair of failed equipment, the most dramatic and costeffective savings can be attributed to addition or trap cooling water conservation kits tothe steam sterilizers.This paper presents details of the testing process used at University of Washington toevaluate the various models of sterilizer trap cooling water conservation kits currentlyavailable. Includes tables.
