That's impressive. But I'm also curious as to what other applications this setup can be useful for, because that looks to be one hell of an expensive operation. It's awesome to see such things actually happening.
While not done with neutrinos (at least not yet), a very similar setup is used for stufying geological structures. Usually either cosmic rays or muons produced by cosmic ray collisions are detected and depending on the number of detections over time, the density of the rock they pass through can be determined. By filtering the energy of the particles, you can look at radiation directionally (particles coming straight down have more energy than those that come at a shallower angle). You can have a detector next to a volcano and get an "x-ray" of that volcano.
Neutrino detectors can also "see" active nuclear reactors. One could imagine using a detector located outside of a suspect nation to validate their claims with regards to nuclear nonproliferation (ie that they're not running their reactors overtime to produce more plutonium than they report).
It was initially used to observe proton decay. By not detecting a decaying proton in the water tank, they could place the mean lifetime of a proton above 10^30 years.
