Water Evaluation Tools

You are here

To assist agencies in conducting comprehensive water evaluations required per Section 432 of the Energy Independence and Security Act (EISA) of 2007, the Federal Energy Management Program developed the Water Evaluation Tools to help in conducting comprehensive water evaluations and water use analysis. Three components comprise the tools:

  1. Handbook: Water Evaluation Tools: This document provides general instructions on performing a walk-through water survey to collect the required data for a comprehensive water evaluation and entering data into the online Water Balance Tool.
  2. Walk-Through Data Collection Forms: Printable forms that provide a format to document the key information collected during the walk-through survey portion of the water evaluation. These are provided in a PDF format to be filled out during the walk-through. Copies of the forms are located at the bottom of this page and in the Handbook: Water Evaluation Tools.  
  3. Water Balance Tool: This online tool provides an automated method for developing a water balance for a campus. The tool provides an output with the estimated potable water consumption by each end-use and compares the sum of all end-uses to the total potable water supplied to the campus. Data collected during the walk-through survey is entered and stored in the tool.

The tool focuses on potable water consumption in major end-use categories at the campus level. The following end uses are covered in the tool:

  • Plumbing fixtures (toilets, urinals, restroom and kitchen faucets, and showerheads)
  • Commercial kitchen
  • Cooling towers
  • Steam boilers
  • Laundry (washing machines)
  • Vehicle wash
  • Landscape irrigation
  • Other processes.
