Water Savings Initiative

Water Savings Initiative

The efficient use of water results in lower operating costs, a more reliable water supply, and improved water quality. Additionally, because energy is required to transport and treat water, saving water also saves energy. For this reason, the Better Buildings Challenge expanded its energy savings program to include water, and helps organizations of all kinds conserve this critical resource. More than 45 partners across the commercial, public, industrial, and multifamily sectors are working with the Energy Department to track water-saving improvements and share successful strategies. Through 2019, partners have saved a total of 8.5 billion gallons and shared more than 160 proven water-saving solutions.

2 for 1: Energy & Water Savings

Energy efficiency and water savings are a combo deal! Learn how you can achieve both energy and water savings in an industrial or commercial setting, and how one often follows the other.

Featured Solutions

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.
The HARBEC water retention pond project supported the company's goal to be "water neutral," or eliminating the need to use municipally supplied water except for drinking and hand-washing. The retention pond enabled HARBEC to conserve over 830,000 gallons of water, without increasing energy consumption.
Loews on-premise laundry system uses an innovative filtration system that allows it to recycle 70-85% of all laundry water. This system is estimated to save the Santa Monica hotel over 4.3 million gallons of water a year. Other improvements related to energy were also completed, showing over $200,000 in savings.
Metrus Energy will save Parrish Medical Center nearly $830,000 annually through energy and water efficiency upgrades using efficiency-as-a-service through an Effiency Services Agreement (ESA).
Nissan installed an automated filtration system at its Smyrna, Tennessee, paint shop, which helped the plant cut water costs by about two-thirds.
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.
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.
