It's just going into rivers and then into oceans. The natural freshwater sources humans use to produce water for municipal water makeup an extremely tiny proportion of the world's water. Consider that 97.5% of the world's water is salt water. Of the remaining sliver of fresh water, the vast majority of that (70%) is frozen in glaciers or snow. Only 0.3% of the freshwater of the world (0.0075% of the world's water) is in the form of lakes and rivers. Even if we dumped 10% of the water from all the lakes and rivers into the oceans it would only raise their height by about 30cm. Then consider something like the Ogallala Aquifer, which is the source of nearly a third of the water used for irrigation in the US, contains only 4000 km^3 total of water. If it were drained entirely it would raise the oceans only about 1cm.
