I don't think they are so much fed from underground sources as they are simply below the water table. Land below the water table is wettened by it and if sufficiently far beneath than water pools. If it can escape at ground level then it flows in creeks or rivers.

There was much more rain in great pyramid building times so there is certainly more water in undeveloped areas. However, where crops are grown a lot of water is pumped in and this affects the level of the water table. Proper irrigation won't raise it too much but ofttimes water is allowed to run off or soak in.

There are a few geologists with knowledge of Egyptology. You might try contacting one of them.

Keep in mind that while there was twice as much rain in ancient times it still rained principally in the winter and pyramid building season started in late-June. I believe it wrapped up around mid-February but this is more difficult to ascertain.
