Water Savings Network

Water Savings Network

Prioritizing water efficiency is a necessary response to the risks of climate change, particularly in water-stressed regions. The efficient use of water saves both money and energy while improving resilience. Through the Better Buildings Water Savings Network, DOE brings organizations together to discuss and demonstrate successful approaches to conserving water in buildings, plants, and multifamily housing. All facility owners and managers are invited to build on the progress already made by Better Buildings Challenge partners who have set water intensity goals and reduced their water use by more than 10 billion gallons since 2015.

Join the Water Savings Network

Partners across the commercial, public, industrial, and multifamily sectors are working with the U.S. Department of Energy to share successful water efficiency solutions and progress, network with peers, receive technical assistance, and more.

Featured Solutions

Tower has taken its water management program to the next level with daily reporting, 15-minute interval data, real-time alerts, advanced data analytics, setpoint modifications, and internal water audits that have resulted in signifigant water consumption savings.
Atlanta's Emory University created WaterHub, an innovative on-campus solution designed to treat and reuse up to 400,000 gallons of water per day, decreasing potable water demand by over one-third. In addition to saving money, the WaterHub is creating scientific and educational opportunities on campus.
To help meet ambitious water-saving goals, UTC developed comprehensive internal guidance that details the company's global water scarcity assessment, best practices in managing water efficiency at individual sites, and water saving case studies.
Anthem implemented a landscaping redesign plan to reduce water demand and create a more resilient environment at the 21555 Oxnard Street campus in Woodland Hills, CA, which reduced its water demand by 46% annually.
The Green Ideas Challenge at The Venetian, The Palazzo, and Sands Expo allowed resort staff to help identify opportunities for energy or water savings, helping staff get more involved in Las Vegas Sands's corporate sustainability efforts.
DaVita created the Top 150 Water Users program to identify and optimize high water users in an effort to reduce portfolio-wide dialysis center water consumption.
Results from two validation studies of new water treatment technologies for cooling towers show 20–50% water savings, improved energy performance, and reduced or eliminated hazardous chemicals.

DOE's Federal Energy Management Program (FEMP) provides guidelines and rules of thumb to estimate daily water use for typical end-uses that drive building-level water consumption. The resource discusses methods related to batch processing/manufacturing, evaporative cooling systems, irrigation, plumbing, steam heating systems, and vehicle wash systems. 
A series of maps and related resources, created by DOE's Federal Energy Management Program (FEMP), that can help organizations implement alternative water projects, such as rainwater harvesting, condensate capture, and wastewater reclamation. Organizations can use the provided map to identify locations in the U.S. that may be good candidates for purchasing reclaimed wastewater.
DOEs Federal Energy Management Program (FEMP) provides strategies for incorporating net zero water elements into the design of projects and ensuring projects operate at net zero water. The resource discusses specific elements such as how to reduce demand, produce alternative water, treat wastewater, and design green infrastructure.
The Whole Building Design Guide (WBDG), developed by the National Institute of Building Sciences, is a gateway to up-to-date information on integrated 'whole building' design techniques and technologies. The WBDG Sustainable Committee organized this overview of improving water efficiency in buildings, making recommendations for water use efficiency and water quality, summarizes DOE FEMP best management practices, and links to relevant codes, laws, and standards.

This factsheet developed by the City of Los Angeles provides information and recommended options for cooling tower efficiency.

Tools

DOE's Federal Energy Management Program (FEMP) outlines the general steps for creating a water management plan, which charts a course for water efficiency improvements, conservation activities, and water-reduction goals.
This Excel-based tool developed by the Federal Energy Management Program (FEMP) enables federal agencies to quickly screen sites for water-efficiency opportunities. It features general information related to a site’s water use and offers recommendations on potential water efficiency projects. The tool provides a qualitative score that indicates low-to-high water savings potential for nine end uses.
These fact sheets, developed by DOE's FEMP, provide an overview of commercially available water saving technologies that offer significant water savings potential.
The excel-based Water Budget Tool was developed by EPA's WaterSense program to comply with section 4.1.1 (Landscape Design) of Version 1.2 of the WaterSense New Home Specification or to ensure a measure of efficiency and regional suitability for the amount of water applied to a landscape based on local climate data.
The Global Environmental Management Initiative (GEMI) and Environmental Defense Fund (EDF) teamed up to scale adoption of the EDF-GEMI Water Management Application (WaterMAPP) toolkit. The EDF-GEMI WaterMAPP is a set of tools and resources that can help organizations build their own program to reduce water and energy use in buildings. It is a MS Excel-based spreadsheet with three complimentary tools: the EDF-GEMI Water Scorecard, the Water Efficiency Calculator, and the Cycles of Concentration Estimator.
