Yeah, I totally get where you’re coming from. It’s wild how much it depends on which inspector shows up—sometimes it feels like a coin toss. I’ve had similar luck with rainwater setups for gardens, but the minute you mention flushing toilets, everyone gets nervous. Have you ever tried a really basic greywater setup, like just laundry-to-landscape? I’ve heard it’s less prone to headaches, but maybe that’s just wishful thinking. Rain barrels definitely seem like the least drama option... but then again, they don’t do much for indoor use.
Honestly, I get why rain barrels seem like the “safe” bet, but I wouldn’t write off basic greywater setups just yet. Laundry-to-landscape is actually a pretty clever workaround and, in my experience, not as intimidating as it sounds. The biggest hurdle is usually just making sure you’re using the right detergents—no phosphates or bleach—and setting up a simple diverter. You can do it with PVC and a couple of valves, and if you keep it gravity-fed, there’s almost nothing to break or leak.
I’ve found inspectors are less jumpy about it if you’re up front and keep things super simple. You’re right though, as soon as you mention anything indoors (like toilets), it’s a whole different ballgame—permits, backflow prevention, the works. For me, the extra effort for laundry-to-landscape was worth it because I got to water fruit trees even in dry months without cranking up the water bill. Rain barrels are fine for a few planters, but if you want to stretch your budget and water more than just a handful of pots, greywater can actually be less drama in the long run... at least outside.
RAIN BARRELS: STILL GOTTA GIVE THEM SOME LOVE
- Gotta admit, I’m still on team rain barrel for a few reasons:
- No need to stress about detergent ingredients. If my kid dumps half a bottle of “super lemon blast” in the wash, my tomatoes don’t care.
- Setup is literally “put barrel under downspout, done.” No crawling under the house or fiddling with pipes.
- Inspectors? They barely blink. My neighbor’s setup looks like a moonshine operation and nobody cares.

“Rain barrels are fine for a few planters, but if you want to stretch your budget and water more than just a handful of pots, greywater can actually be less drama in the long run...”
- Maybe my fruit trees are just lazy, but two 55-gallon barrels kept them alive last summer. I mean, they didn’t exactly thrive, but neither did my wallet.
- Not saying greywater isn’t cool (I’ve watched enough YouTube to be tempted), but for folks who want cheap, no-fuss, and zero chance of accidentally flooding the crawlspace... rain barrels still win some points.
RAIN BARRELS: SIMPLE, CHEAP, AND STILL WORTH IT
Totally get where you’re coming from—rain barrels are hard to beat for sheer simplicity. I’ve tried both, and honestly, the rain barrel setup is just less stressful. Greywater’s great in theory, but the plumbing tweaks and the “what if I mess this up” factor kept me up at night. My barrels aren’t fancy, but they keep my herbs alive and I don’t have to worry about what’s in the water. Sometimes the low-tech route really is the best fit.
I get the appeal of rain barrels—hard to argue with “simple, cheap, and still worth it.” But I do think greywater deserves a bit more credit, especially if you’re looking at long-term water savings. The plumbing side can be intimidating, sure, but once it’s set up, maintenance isn’t as bad as it seems. Most systems just need a filter check and a flush every now and then.

Honestly, I felt the same way at first. But after helping a neighbor install a basic laundry-to-landscape system, it was less complicated than I expected. There are kits now that really cut down on the guesswork. Plus, you can use greywater year-round, not just when it rains. That’s a big deal in places with long dry spells.
I’m not saying rain barrels don’t have their place—they’re great for herbs and small gardens. But if you’re up for a little extra work upfront, greywater can be surprisingly manageable. Sometimes the “harder” route pays off more than you think.
