My question probably has an obvious answer (in theory) - but might have real world nuances? Assume you have a standard well with typical increasing water flow with increasing depth and you want to use it as a return well in a standard 'pump and dump' setup. Does it matter if the discharge pipe in such a return well is at the top or bottom of the well with regard to getting the best 'return flow' back into the ground? Does the height of the water in the well increase any differently? Does the the depth of the well matter here? I immediately think it's obvious, but then I second guess myself here. Thanks to anyone who wants to take me to task here.
