We dug a ditch around the perimeter of 1 side, with several entries under the sill of the building and then the rain water runs into the hoop on that 1 side into another channel inside the hoop (a terraced bed adjoins that side of the hoop, to flow into the hoop). From there, the rain and run off (an enormous amount of rainwater runs off of the hoop house itself) goes into a channel, flows down the center of the hoop and into the keyhole beds. Our productivity is far greater than with traditional rows. The west facing inside of the hoop (we ran it North/South) is filled with large rocks to act a heat sink. We do not use artificial heat, but do use row covers inside the hoop if temps are going to get extremely low for us (below 15 degrees). Works really well. Y'day I seeded several beds with root crops, since we're getting so much braising mix, lettuces, spinach, arugula and cilantro that I need some new stuff. Hope this helps.

how well does the structure handle wind
up here in the Keweenaw of Michigan we get a lot of wind off the big lake [30-40 mph]
the way the beds are layed out are a great idea with the walk ways into the bed [key hole]
