Need to store rainwater and runoff at my Ajman farm – is an IBC tank overkill?-Forum-Culture Informatique

I’ve got a small plot of land out near the edge of Ajman where I’m trying to grow a few things, and I’m tired of watching all the rainwater from the occasional winter storms just run off into the sand. I started looking into storage solutions and kept seeing these big square containers on pallets that people use for all sorts of liquids, so now I’m wondering if getting an IBC Tank would be a smart move or just way too much for what I need. I don’t have any industrial requirements, just want to collect maybe a thousand liters max to use for watering during the drier weeks, but I’m not sure if these tanks are easy to clean or if they leach anything into the water. Also, would I need to build some kind of stand to get gravity flow or can I just put it on the ground and use a small pump? I’ve seen some used ones for sale but I’m nervous about what was stored in them before. Anyone in Ajman using one of these for simple water catchment? Would love to hear how you set it up and whether you regret going that route instead of just buying a few plastic barrels.
