Drainage problem

[mountaindweller]

We've planted some fruit trees tightly spaced as they have to be netted. Our soil is awful crappy fill with lots of concrete pavers asphalt and what not. I thought the best would be dig the whole site out get compost and leaves and good soil in, so we did two years ago. What I didn't realize back then is that the drainage as well is miserabele and now we have created a bathtub.
It was incredible rainy last summer and the water is puddling there.
None of the trees died so far and they are between 1.5 and 2.4m high.
I think of digging the trees out one after the other. Digging a hole for each tree, dumping down sticks then grass and then create a hill out of the soil and plant the tree back. This is somewhat inspired by Sepp Holzer.
I am not quite sure because as the timber breaks down so does the hill, but how do I get that much soil otherwise? The other problem here is that now it's wet but the drought will come back - maybe.
(BTW it's mid winter here, the ideal time to do this job)
Opinions?

Would it make sense to put in weeping tile?

What is a wheeping tile??

That is to say, could you put in a drain, or is it uphill in every direction from your bathtub? It might be less work to ditch out and put in a drain, than to raise all the trees. You just need a place downhill to dump the water out.

It doesn't really go downhills it is pretty flat. The trees are not too big now. (I am very sure if I raise the trees or put in a drain, then it stops raining altogether immediately)

Ideal scenario would be to cut a drain to lower ground, if there really isn't lower ground maybe you could make a french drain somewhere to take the water lower?

There are only 10 trees. I find it far easier to replant and raise these, but I'm not too sure weather this will do the trick. The whole site is relatively even - these i... dumped all that rubbish on a swamp, and as there were a certain lack of intelligence they evened the whole 1/2 acre out (mostly).

I know a bloke who had a terribly wet block of land so what he did was he used a digger to made 1.5- 2 m high ridges,5m wide,this was where he planted his fruit trees on top of and in between the ridges-rows was the drainage area,worked really well.

If you are going to replant them, then it makes sense to reshape the land yourself so that there becomes a lower spot for water to drain into. Around your raised area, put in ditches to divert the water away. Something like richardw said or your own land sculpting idea.
