That's an understatement! The Super Kamiokande project alone pioneered at least a dozen technologies and improvements now used by much of the particle physics, nanotech, semiconductor fabrication, high precision sensing, and even biotech fields.

The technologies developed for water purification are especially marvelous. The Super Kamiokande is full of water that is likely the purest substance in the solar system (at a macroscopic level, although maybe there's crazy bulk gluon plasma at the center of the sun).
