What can be done for a water spring under the house?

Dig a hole about two feet deep at the spot where you see the water running out of the ground, put some rocks or gravel at the bottom, and put a float type bilge pump (You should be able to find one at any hardware or home improvement store) in there with a hose running to the downhill side of the house. The above answer is a basic 'sump pump' installation. Also research 'french drain' as an alternative to passively relocate water flow.
