I'm putting a lot of earth tubes into my house, as part of my heating and cooling
All the easy water is downslope, I am hoping to have money for a low speed wind pump to raise water up to work with. Got good constant low breeze.
with that much slope and all that pvc it sounds like a hydroelectric power plant waiting to be put to use. a 4 inch column of water fed from a reservoir up high could supply a lot of energy
Not if I pay attention. I have told my mom since we started the planning "It's easy to design for hot, or cold, for wet or dry, but this area alternates all of those, that's a hard one to deal with." So the weather is lovely here, except when it's screaming hot and muggy, or ice storming. The neighbors talk of "wet years and dry years" and no in between years. So the water control systems (swales, ponds, french drains etc) both keep the water on the property, and deal with excess. The house assumes hot and cold weather are both going to happen. If I wasn't paying attention, yeah, there would be issues. The neighbors just had to do a major rework of a lot of their yard due to the gutters basically dumping right into the basement. Hoping to not have to do stuff like repair messes like that.
sounds like you have some serious water control issues
The only reason I'm going straight down is to pull up only cool air from the foggy creek area, knowing I'll have the south side tubes too. If I were doing only one I'd be doing what you are :) Gets back to the extremes here.
the result being a slight downward slope to the tube over all, but less than it would be if I just went straight downhill.
I think you are correct there, for at least the start of the season. Might be less effect mid-season. Still going to help a lot!
In fact, I believe drawing air through the ground like that will heat the tube in summer so it will be warmer than the 55 degrees or so I expect at that depth. then after drawing cold air through it all winter by the time summer returns, the tube will have cooled considerably supplying even colder than usual air
I'm jealous of a backhoe!! Sounds like you have a plan too!! :D And possibly a house already there. I don't have a house, just old foundations from a house that burned, that are older than I am, and I'm not reusing them. I'll use them to protect the plants I'm propagating, easy to hoop it if I want, bit of wind protection etc.
I'll be renting a backhoe to finish dams and swales of my mainframe water design--the earth tube is just a side project. things are already pretty good so a simple earth tube should put my cooling needs well over the top, and solar hot water through a radiant floor should even eliminate the rocket heater most of the time.

the 100 foot tubes from the bottom of my north slope, buried 2-3 foot deep, should drop the temperature coming in about 25-35 degrees and the humidity by about 30-40%.
