Water reduction initiatives allowed us to reach our water intensity goal four years early. Now, we’re sharing our playbook with others.
GM was recognized on the 2017 CDP Water A-List for effective water management practices implemented around the world.
GM is committed to finding ways to not only reduce water used in our operations, but to extend the benefits of more efficient processes to others. For example, we recently finished our first full year reusing stormwater for process water at the Detroit Hamtramck Assembly plant. The savings equate to nearly $2 million per year for GM. The savings also benefit the city of Detroit: by creating a pond to collect stormwater, we reduce stormwater discharge. Some of the collected water is sent to Detroit Renewable Power, where it is turned into steam that heats and cools the assembly plant and 145 other Detroit businesses. GM is looking to replicate this concept at other sites with similar environmental conditions.
We are communicating best practices by leading a water benchmarking workshop within the Automotive Industry Action Group, which recently resulted in a white paper for OEMs. In addition, working with the Water Environment & Reuse Foundation, Arcadis and other industry partners, GM shared details on our water reduction and reuse initiatives. Our input helped form a framework for successful implementation of on-site water reuse in industrial applications.

GM also joined more than 900 other organizations in the Better Buildings Challenge, setting a goal to reduce our water intensity by 20 percent by 2020 in 31 U.S. plants. We met the goal four years early, reducing water intensity by 28.3 percent against a 2010 baseline.
