About the Water Efficiency Rating Scale (WERS)

WERS is a performance-based water efficiency program for both new and existing residential properties. This approach to water efficiency preserves design freedom and product choice flexibility. Third-party analysis and data collection is utilized to generate both a score and predict water usage for single-family and multifamily properties.

WERS History & Design

The Water Efficiency Rating Score (WERS)® is a third-party verified tool that is used to predict water use for new and existing properties. The Program was codified in the City of Santa Fe as of October 27, 2016. WERS currently utilizes spreadsheet technology for implementation. When the web-based app is fully programmed, there will be an online version for WERS Consultants & design teams, and a field application for WERS Verifiers. The online version for design teams will not require as much initial information to generate a preliminary WERS. What we present on this site is the data collection necessary for the Verifier.
