Put in a cistern to hold the water. Start where the water is comming out of the ground and dig a trench back, following the flow of the water, about 10 feet. Put in black perforated pipe with a screen cap on the end in this trench. Put a tank (concrete or plastic work well, you can even build one out of brick, just make sure you seal it well, use as large a tank as you would like to have reserve water) in at the down hill end of the black pipe, you will need to dig a hole large enough for the tank. Connect the black pipe with the tank, as near the top as posible, put another pipe coming out the top of the tank for overflow. Put your out flow pipe about 4 to 6 inches from the bottom, use 1 inch ABS, once again with a screen cap, and run this line to where you want to access the water. You want to bury the outflow about 6 to 12 inches below the frost line. If you are using a plastic tank, let it fill with water, then backfill the entire setup, including the perforated pipe. Mark where the access hole is on top of the tank, so you can find it to periodically clean the sediment from the bottom of the tank. Set up properly, this type of setup will last as long as the water continues to flow from the ground in that area.
