mhulbert's idea is a good one, short of installing a sump pump.
It may very well work, so long as that drainage in the Chisty does not saturate.
Is the water from run off, or ground water below the surface?
If run off, you can extend the conduit higher up in the Chisty and seal it, so it doesn't act like sink drain, and improve the drainage in that box.
If it's ground water, and the slightest leak in the conduit you may be SOL. You have few options, locate the leak, and fix it. Or abandon it, and start fresh. You still need to stop the water, right? Mix up a slurry of cement, (portland milk-shake) cork the end at the house, fill, and start over. 100' of 1" may take 100lbs, and 50 gal of water to fill with slurry, but you only need to the end at the house, so maybe less... Too bad you can't still use the conductors and pipe after that.
I grouted some clay voids in my yard that way, and it worked great at stopping the water.
