Hi,

Has anyone used old wine barrels as rain barrels??  I am considering this. I found a site that sells them with a spigot and netted hole on top for a reasonable price, but I do not know the long term life of a wood rain barrel in the elements. 

The reason I am consider this is that plastic worries me, esp outside where it's exposed to sun/heat.  I know I shouldn't be trying to make my life harder :) but I am active in Beyond Plastics and learning about plastic in our world (actively advocating for natural grass sports fields in SF Bay Area) and so when the idea of rain barrels came up, I had to pause to consider the material.  There is concern about PFAS and other chemicals in plastic leaching into water. https://www.epa.gov/pesticides/epa-releases-data-leaching-pfas-fluorinated-packaging

PVC pipes are not so great.  We can't do much about rubber tubing etc, but there is some theory that when water just runs through plastic and doesn't sit stagnant in it, it might not collect as much or any chemicals.  However, with the rain barrel idea, i am not sure in  our school setting that we would regularly empty it. 

I did do some calculations and it is possible if we are actively using it, we'd run through the water quickly.  And we are planning on using them more as water tanks so filling with hose water rather than collecting rain since one location does not have a good collection roof.

I am seriously considering wine barrels.  I might just get one to try it too, but I thought I'd check in this group in case anyone has experience with it.

Thanks!

Hi Pam,

Material planning and long‑term sustainability are essential. Wine barrels can possibly be used as rain barrels although I prefer rain barrels myself. Wine barrels are often preferred because they look nicer and allow a person to avoid plastic, however, there are a few things to keep in mind:

Wood barrels will expand and contract with the weather. If they're kept consistently moist, they can last for years, but if they dry out too much they may shrink and leak. Some folks line them with a food‑safe sealant to extend their life. Wood also requires more care. You have to check for cracks, keep them in shade, as well as possibly retightening bands. Your concern about PFAS and plastics leaching is valid. Using wood avoids that issue, though you'll still want to think about what fittings you use (spigots, tubing, etc.). Stainless steel or brass fittings are often recommended over PVC.

Since you mentioned filling with hose water rather than roof runoff, the barrels will be more like storage tanks. If students are actively using the water, that turnover helps prevent stagnation and keeps the barrel in better condition. Begin with one barrel as you've stated and see how it holds up in your climate and your usage pattern before investing in more.

I admire that you're connecting this project to your Beyond Plastics advocacy because it's a great example for students to see how everyday choices tie into bigger environmental issues. If you go ahead with a wine barrel, I'd love to hear how it works out.

Thanks,

Tina
