^^^^^ That really depend on what one mean with concentrated. By mass Earth is something like 0.02% water. C-type asteroid which are something like 75% of all asteroids in our solar system can be 10-22% water. Jupiters moon Europa is mostly water and may contain twice as much water as Earth. Most starsystems with aliens would probably have C type asteroid outside the 'frost line'. Getting to that is much easier to get to than interstellar sources.
