Can I water my lawn this way?

A question about the lifting capacity of sponges, gravity, pvc tubing and whether my lawn can be irrigated.

The water table under my lawn is very high. That is, when I dig a hole for a fence post, at about the three foot mark, I hit water.
Please tell me if this is physically possible.
If I take a four foot length of PVC pipe that is 5 or so inches in diameter, fill the pipe with high quality sponges to the top, and then place the pipe vertically in the hole, with the top 12 inches sticking out of the hole, will the water seep out of the top of the pipe where it can be collected?
More technically, is a sponges lifting capacity eventually exceeded by the force of gravity?, and if so, is four feet to great of a distance for lifting capacity to exceed gravity?
Alternatively, suggest any other reasons this will not work.
