Slash Water Use with Free Resources

摘要

Asuite of free water efficiency tools can help buildings (especially those with cooling tow-ers) reduce their water demand by 14-40%. The Building Water Efficiency Toolkit was developed through Environmental Defense Fund pilot projects at AT&T facilities in summer and fall 2012. The telecom giant opted for the measures that made the most business sense, such as an upgrade to a cooling tower filtration system that cost under $100,000 to install but is predicted to result in over $60,000 in annual water and sewer savings.
