Growing Together: Open Forum

Hi,

i wanted to see if anyone has tried using a used wine barrel for rain water collection.  I found a site that sells them with a spigot and netted hole on top for a reasonable price.   There are also places that sell the barrel without connections.

i am concerned about plastic because the best information that I have is that as long as the water is moving through the plastic barrel and not sitting in it for a while it's probably ok (regarding chemical leaching) but I can't guarantee that water won't sit sometimes.  And there is no hard info about it definitely being ok.  I know it might seem overly careful to some but I am involved in plastic research related to artificial turf (advocacy for grass playing fields) and it is concerning.  

I am just looking for people with experience or second hand knowledge of how a wine barrel holds up for rain water.  (Technically two will be filled by a hose as sort of a surrogate water tank because we don't have a good collection site but can't leave a timer hooked up and on at the hose spigot - district rule.)

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
