WaterSense Commercial Tools and Training

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 pp, 6 MB, 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 provides a detailed description of the project the facility implemented and how much water, energy, and utility costs they were able to save.
