We primarily use water for the cooling of our data centers. Therefore, to save energy related to cooling, we must occasionally increase water usage. We are continuously working to balance our energy and water usage and particularly work to reduce our use of potable water.
As part of our commitment to minimize our freshwater footprint, we frequently utilize rainwater to cool our data centers when possible. For example, a recycled water cistern at our VA2 site installed in 2017 saved 1.2 million gallons of water in 2018. CoreSite maintains an additional cistern at our VA2 data center, which holds 80,000 gallons. These projects not only reduce our freshwater consumption but also increase our operational resilience.
