I wouldn't want to use any electrical power to get water into the ground.
The soil where I live has a large amount of sand, and in most cases, surface rain easily moves into the ground. So, spilling it over the field would work.
Occasionally however, we get a very heavy rain and I think a couple of 'leech lines' (perforated pipe buried amidst a gravel bed) would take care of the unusually hard rain.
Where I live, the annual rainfall is just short of a meter per year! With most of it falling in the winter, and very little falling in the summer.
That winter rainfall could be very useful for heat extraction.
