Case Studies
Throughout the country, commercial and institutional (C&I) building owners and facility managers are taking actions to reduce their water use, implementing many of the operations and maintenance, retrofit, and replacement projects described in WaterSense's C&I best management practices guide, WaterSense at Work (308 pg, 5.38MB, About PDF).
WaterSense is gathering and documenting case studies to describe successful water efficiency efforts, which will provide an avenue for sharing information within and across C&I sectors. Each case study below provides a detailed description of the project the facility implemented and how much water, energy, and utility costs they were able to save.
