Landscape fabric is key, but make sure it’s not too tight or it’ll clog. Sometimes I’ll even put in two smaller wells instead of one big one, just to spread things out.
I hear you on the clay—had a backyard once where water just sat on top for days. If you’re set on dry wells, I’d double up on the gravel like you said, but I’d also try a shallow trench leading to a rain garden or some thirsty shrubs. That way, if the wells fill up, you’ve still got somewhere for the overflow to go. And yeah, sloping the pipe is huge... learned that the hard way after a soggy crawlspace surprise.
I’ve definitely been down the “dry well in clay” road before, and it’s a bumpy one. The first time I tried it, I thought I was being clever—dug a big hole, filled it with gravel, wrapped it up like a burrito in landscape fabric. Looked great until the first big rain, then it basically turned into a bathtub. Turns out, clay just doesn’t let water go anywhere fast.
I like the idea of splitting up into smaller wells, but honestly, if your soil is stubborn, you might be better off thinking about where you can direct that water instead of just trying to bury it. Trench to a rain garden or even just a patch of lawn that can handle getting soggy for a bit is smart. I’ve seen folks run pipes out to the curb (if your city allows), or even into a dry creek bed lined with river rock—looks nice and gives the water somewhere to chill out.
One thing I learned the hard way: don’t skimp on the slope for your drain pipe. Even half an inch per ten feet makes a difference. My first attempt was “level enough” until I realized water doesn’t really care about my optimism.
Also, if you’re draining pool water specifically, keep in mind some plants don’t love chlorine or salt (if you’ve got a saltwater pool). Maybe let it sit in a holding tank for a day or two before sending it off to your shrubs—just gives things time to mellow out.
Anyway, there’s no perfect fix for clay-heavy yards but spreading out the flow and giving overflow somewhere to go has saved me more than once from backyard lakes. And yeah... landscape fabric is great until it turns into a coffee filter and clogs everything up. Learned that one after digging everything back up mid-summer—wouldn’t recommend.

That line cracked me up—been there, done that, got the soggy shoes. Have you ever tried using one of those rain barrels or big stock tanks as a temporary catch? I’ve wondered if letting the pool water chill for a bit before releasing it would help with both the chlorine and the “instant swamp” effect. Or does that just delay the inevitable backyard lake?
Letting the water sit in a barrel or tank does help with chlorine, but honestly, I’ve found it doesn’t do much for the “instant swamp” problem. Once you dump a bunch of water in one spot, it’s gonna get soggy no matter how long you wait. I tried the rain barrel trick last year—ended up just moving the puddle around. Have you looked into using a soaker hose to slowly release the water over a bigger area? It’s not perfect, but it spreads things out a bit more.
- Totally get the “instant swamp” issue—been there, got the muddy shoes to prove it.
- The soaker hose is a decent hack, but if your yard’s anything like mine, it still finds the lowest spot and turns it into a mini pond.
- I’ve seen people use decorative gravel trenches (fancy French drains, basically) to help water disappear faster. Not exactly glamorous, but hey, it beats a backyard bog.
- If you’re feeling ambitious, you could even turn that soggy patch into a rain garden. At least then the mess looks intentional... sort of.
