A new 100,000-gallon reservoir and 3,000 feet of new water pipe are part of an expanded fire suppression system in the Sanford Underground Research Facility in Lead's former Homestake gold mine, according to a Sanford lab news release.
The pipe connects the science lab's Yates campus to the Ross campus, two sections of the labyrinth of tunnels served by two head frames that each house an elevator. The water also will be used for cooling and drilling, and it allows the state-owned lab to expand further to allow in more experiments.
During 2015, the lab added 1,425 square feet of servicable space for two projects, the Black Hills State University Underground Campus and an experiment known as CASPAR (Compact Accelerator System for Performing Astrophysical Research.)
