Given a big budget, you can make the pumped-pool-liner water supply work, but you have to determine how much of a flow you can sustain. Don't expect much, but you might luck out. It takes the combination of high water table and sandy or gravelly soil to get the best results. Figure a half-horsepower pump, which, by the way, is about all you can run on a typical circuit. If you test it out, and get a sustainable flow, come back for further advixe. Come back anyway, to inform us of the test results.
