Sourcing lake water for cooling
Our aim is to reduce pressure on nature. So we have set a target to reduce our dependency on ground water, a resource that is more and more scarce.
Therefore, we partnered up with the local utility company in Falun to instead source surface water from the nearby lake Rogsjön, pictured above with Falun in the background.
We invested around 20 million SEK to lay new pipes and upgrade the water processing system, to start using surface water of poorer quality from Rogsjön rather than ground water. That means we can use filters rather than chemicals to clean the water to meet our technical requirements.
We use this water source for the newest building, Data Center 1C, and will do the same in the remaining centers. There are good reasons for doing this.
