CASE STUDIES

N.C. State University: To meet the environmental challenge of the 2008 drought, NCSU's Building Maintenance and Operation department evaluated uses of water in classrooms, research and office buildings. After tackling the obvious water-using sources, the team developed three criteria for water reuse projects. Click here for the full case study.

John Umstead Hospital: The John Umstead Hospital in Butner, NC is a 593-bed psychiatric care facility serving 16 counties in the north central region of the state. The hospital joined the Utility Savings Initiative and created a Conservation Awareness Team in 2003. By redesigning the cooling system for four ice machines to use an existing cooling tower the hospital was able to save 429,000 gallons of water a year. The entire cost of this project was $800, compared to a utility savings on water of $2,016 per year. Click here for full case study.

Duke University: Facility managers of both the Levine Science Research Center and Gross Chemistry Building on Duke’s Campus used practical upgrades to save more than 9 million gallons of water per year between the two facilities. This translated into an annual cost savings of $24,700. Click here for full case study.

UNC Chapel Hill: Efforts to use water more sustainably have led to a focus on conservation and efficiency. Required by N.C. State Executive Order 26, the University has developed a Long-Term Water Efficiency Plan, which identifies many opportunities to conserve water. UNC is also promoting behavioral changes, including water conservation and proper watering techniques, through education. More than 160 water-free urinals have been installed throughout campus saving 2.1 millions gallons per year at a utility cost savings of $17,300 annually. Click here for full case study.
Dept. of Corrections: With 78 facilities across North Carolina, our state prisons are significant water users. The Division of Prisons has developed plans for its facilities to monitor and track water usage and reduce consumption in many ways. Click here for full case study.
