We reduced water usage by 17% from 2010-2013, with an annual reduction of 3% from 2012-2013. To achieve this progress, we upgraded heating and cooling equipment at many sites and implemented water conservation and re-use opportunities.
Lockheed Martin's water program is focused on attaining the Corporation’s Go Green goals for water conservation through increased efficiency, on-site water re-use, and best management practices at all facilities. Our strategy is currently expanding to focus on water reduction activities at facilities located in water-stressed regions. In 2013, when we established the Go Green 2020 goals, we established an objective to place a stronger focus on water risks in water-stressed regions.
We completed a preliminary assessment of our water risks using the World Business Council for Sustainable Development (WBCSD) Global Water Tool in order to identify which of our facilities in the U.S., Australia, and Canada, Mexico, and the U.K. are located in water-stressed regions. The goal of the analysis was to prioritize future water related initiatives in geographic locations based on water supply indicators and drought indicators. The results of the assessment showed that approximately 60% of our total operations based on employee count are located in water stressed regions.
Water reduction efforts at our sites include:
- The Reverse Osmosis system at our Marietta, Ga., facility reused 27.5 million gallons of water, making it a major contributor to the site’s water reduction efforts. The system re‐uses water from the waste water treatment system and has provided water reuse to cooling towers.
- Employees in Valley Forge, Pa., implemented water savings measures, including installing a system to treat recirculated cooling tower water. The system uses non-chemical treatment that uses electrostatic precipitation to remove impurities from the water so that it can be returned to the system and reduce the amount of make-up water required and is estimated to save more than 3 million gallons of water per year.
Thirty-six U.S. facilities conduct additional procedures to ensure facilities are in compliance with pollutant and stormwater discharge and industrial wastewater requirements. These sites are regulated under National Pollutant Discharge Elimination System (NPDES) general stormwater discharge and/or industrial wastewater discharge permits.
We take proactive measures to reduce negative operational impacts on the environment. For example, our Marietta, Ga., facility operates a sanitary wastewater treatment plant that discharges into a nearby stream. The outflow replaces water flow to the stream that had been lost because of residential, commercial, and/or industrial development.
Endangered or threatened species are known to be on-site or nearby 43 of our facilities In addition, 32 of our sites have designated wetlands on their property and an additional 42 of facilities are located adjacent to wetland areas.
