Water Management The impact of water availability is a localized risk. Some regions are already experiencing water stress, while others have abundant water and are expected to continue to maintain a reliable supply into the future. In 2019, we conducted a water supply risk analysis to identify our facilities in the highest water stressed regions and those predicted to be in stressed regions out to 2040. In 2021, we used this analysis, along with a ranking of our highest water using facilities, to prioritize and execute water balances and associated water conservation activities. We’ve completed five water balance analyses at facilities in Fort Worth, TX, Waterton, CO, Palmdale, CA, Sunnyvale, CA, and Marietta, GA. In addition to mapping where water sources originate, how it is used in these facilities and how it is discharged, the analyses identify opportunities for efficiency. These opportunities will receive additional scrutiny, with an emphasis towards calculating water efficiency projections based on the true cost of water. This means considering not just the cost of the water, but also the cost associated with pre-treating, pumping, heating and disposing of the water. Go Green Gated Capital and Water Efficiency Water efficiency projects are also considered during the Go Green gated capital cycle discussed in the Energy Management section of this report. For example, in 2021 three water-saving Go Green projects were completed: • Cooling tower filtration system at our Missiles and Fire Control facility in Troy, AL, which avoids 6,307,200 gallons of water per year. • Ambient air nitrogen vaporizers at our Rotary and Missions Systems facility in Bridgeport, CT, which avoids 26,400 gallons of water per year. • Cooling tower upgrades at our Space facility in Sunnyvale, CA, which avoids 43,000 gallons of water per year. Additionally, funding for an air scrubber project at our Aeronautics facility in Palmdale, CA, that will avoid an estimated 450,000 gallons of water annually, was earmarked for 2022. TOTAL WATER CONSUMPTION (MILLIONS GALLONS) a ENVIRONMENT, SAFETY AND HEALTH EXCELLENCE AWARDS RECOGNIZING WATER CONSERVATION As part of the Lockheed Martin 2021 Environment, Safety and Health Excellence Awards 22 , an Aeronautics facility submitted an efficiency project with significant water savings. By installing an energy management control system that manages chlorine meter flush systems at specific building locations, the facility was able to maintain chlorine levels while eliminating unnecessary discharge into the sewer. The project saves approximately five million gallons of water, with a projected simple payback of nine months. The standard best practice going forward is to install these energy management control system-controlled stations at the facility where applicable. a Data is shown for our Go Green year, which runs November-October (e.g. Nov. 2020 - Oct. 2021). 22 The Lockheed Martin Environment, Safety and Health Excellence Awards is an annual, company-wide program run by the Corporate Environment, Safety and Health team. The program aims to recognize projects or teams that have made a significant contribution to the business through their dedication to improving performance.
