@karenspeer7378 Hello to you.

Welcome back! We love your new pupp. He's so cute. You are giving us great inspiration for our build, we will probably do some similar drainage here with our build. I'm going back to working on our gabions, I'm building 20, and the wind has finally calmed down, so I can do some welding. Thanks for sharing, and as always, keep building 👍

@ToddLarsen It is a cold windy day (April 6, 2024) in SW Montana. Got a winter storm advisory. Working on greenhouse though. Got drain field buried and moving to finish air ducting along north wall (same as front that we covered in Step 13), then on to backfilling. Thanks for the comment about the new CSV pup. He is a corker. Like me, he hates the wind. Cheers, J&K

Seen a lot of engineered systems for drainage where the pipe is burrito wrapped with the fabric for extra protection from fines and holes are down due hydrostatic pressure causing water to rise and allowing water to channel out on the thin curved portion of pipe. Looks like you’re using a ton of rock outside of your lay line so I think you will be just fine.

@cgparas thank you for your comment. I agree with the method you described especially if you live in an area with a lot of ground water at high levels and/or clay. We live in what is considered a semi-high desert. Our problem is never ground water. Our static water level is 90 feet down. Having said that, our concern is with water coming off a giant wedge of a roof. We plan to do gutters, but still need to divert that water when it rains/snows. Cheers, J&K

@@montanalivinginthebigskyco8541 You have an opportunity to add some big cisterns at the end of each drain field with a surface aces sable filter box and hand/solar pumps to pull from them or to feed a drip system, ect. Having some free rain water for plants is always a good thing to have, especially if your well pump dies or the power goes out in an arid region.

@bigmambahful You are exactly right, but if we go commercial greenhouse, which was our original purpose, we are prohibited in the US from using rainwater off a roof because of contaminants, like bird poop - unless we put in a purification system and the water sampling requirements are a pain. Having said that, we do divert our rainwater off our house roof into the trees around our home.
