Aquanet

Summary
Across the entire surface of Venus, rain that turns to ground water has been interacting with various minerals. In many places, the acidic water has eaten away mineral deposits and created vast networks of caves. These new caves combined with even older networks that appear to have been created in a slimiar manner. This massive cave network extends to the sea, acting like a sponge. Depending on a number of factors, such as the position of the sun and the moon Apollon, the time of day, and the distribution of rainfall, the ebb and flow of water through the labyrinthian rises and falls. The majority of these tunnels are fairly deep, about half a mile to a whole mile down on average. Accessing this complex water table and knowing when certain wells will active is very important to people living in the wastelands. Major cities and oasis towns have the technology to dig deep enough that such variations have less of an affect, though droughts are always possible.
