How much water has Duke saved?
Duke is tracking its water reduction using two baselines: daily and year-to-date consumption. Duke’s daily water use in most campus areas dropped from a little over 2 million gallons per day in August to approximately 500,000 gallons per day in February – a reduction of more than 70 percent. That data is based on meter readings for about 90 percent of Duke’s total square footage. Based on the year-to-date tracking, Duke reduced water consumption in most campus areas by nearly 28 percent between June 2007 and February 2008 compared to the same period in 2006-07.
