@sbeer6er length has nothing to with it, it's the elevation drop or "head" that effects the power and efficiency this system has. the head is the height the water is falling from, the only reason the length of the pipe is a issue is when you need to have a long pipe to get enough elevation throughout the pipe, you're only trying to get elevation here. for every foot of head, you gain .433 psi, then you just need to figure out how much psi you need for the elevation your going to pump to.
@Cathonius barely noticeable if it's made in the proper spot, you need elevation, not pipe length. the water velocity can actually be a problem, you want as much pressure as possible, which is caused by the drop, not the speed of the water.
Like the return pipe idea. Most I have seen just spill the water down the hill.

how long is your drive pipe? I'm thinking about build a ditch pump by my house.

"length has nothing to with it" - wrong, it has impact on water velocity
