The main rings of Saturn contain approximately thirty five trillion trillion tons of water, frozen in suspension for the most part, with trillions upon trillions of tons of various other compounds and raw elements. Just accounting for the water alone, this represents about twenty six million times the amount of water on earth, orbiting Saturn.
The
Cassini Project has photographed geyser activity, not only upon several of the moons circling Saturn, but within massive conglomerates which orbit as parts of the rings. This indicates, without question, that there is liquid water beneath the surface of many of the moons and massive formations orbiting Saturn.
Sorry, forgot to link the geysers:
