New here and hoping I don't repost a question that has already been addressed. I've done a forum search, but can't seem to come up with an answer. If I missed it, please head me in the right direction. We are looking to create a water catchment system and are not sure what type of barrel to use. We prefer barrels as they are over abundant in our area (AKA cheap). Yet, we can't decide which to use. We have the Jack Daniels Distillery just a few miles up the road, and several other factories where we can get wooden barrels for a good price. We can also get the 55 gallon blue (plastic?) drums from other places locally for a reasonable price. Has anyone done any research on this to determine which one is best for long-term? I know the blue drums have a tendency to split over time, but wood also rots if not treated well. What about bacteria reduction? Thanks!
