Methodology for a Comprehensive Analysis (Triple Bottom Line) of Alternative Water Supply Projects Compared to Direct Potable Reuse

The purpose of this project was to develop a quantitative framework with an accompanying tool for utilities to conduct a triple bottom line (TBL) comparison of various water supply and treatment options, such as direct potable reuse projects, indirect potable reuse, groundwater or surface water development, desalination, and demand management. The resulting Water Supply Evaluation Tool (WaterSET) can convert user inputs related to treatment, transmission, and overall operations to impacts across multiple TBL criteria. The report presents the conceptual and theoretical framework underpinning WaterSET. The User Guide provides a step-by-step explanation of the underlying data and calculations at each stage.
