Customer Reviews
IBC tote was good
Bought an IBC tote. Arrived quickly. Product was as expected. No issues. Would order again from them.
Decent service, minor hiccup
I ordered a 1000-gallon septic tank from Tank Depot. The price was competitive, and the customer service was helpful when I called to confirm delivery details. Shipping took 8 days to reach my rural address, which was acceptable for such a large item. My only minor complaint was that the delivery driver didn't call ahead like I requested, so I had to rush home from work. The tank itself is solid though, seems like good quality for the money. Overall, a pretty good experience, but they could improve communication on the delivery end.
Consistent quality, fast delivery
This was my third order from Tank Depot, a 300-gallon vertical water storage tank. Like before, the delivery was prompt, arriving in about a week, and the tank was exactly as described. Their products have always been reliable for my agricultural needs. Good to know I can count on them for these types of purchases.
Amazing tanks, so happy!
I just received my new 500-gallon potable water tank, and I'm so happy with it! The quality is fantastic, very sturdy construction. It arrived much faster than I expected, only 4 days to my door. The whole process was smooth from start to finish. I'll definitely be getting more tanks from them for other projects. Highly recommend Tank Depot!
Got my rain barrel!
So I finally got around to buying a rain harvesting tank from these guys. It arrived in about 6 days, which was pretty standard. The tank looks good, just like the picture. My husband helped me set it up last weekend. It's been raining a lot since then, and it's already working great. No complaints, easy peasy.
Tank Depot Community Discussion
Share tips, ask questions & help fellow shoppers save more
My contractor mentioned getting a discount if he orders a bunch of tanks. Is there a special program for contractors or just a general bulk discount they offer?
Comparing the poly vs steel tanks for a new fuel setup. Which one holds up better long term? Any big differences in maintenance?
Are these tanks legit for drinking water? Like, if I get one of the big water storage tanks, is it actually safe for potable water?
Hey, thinking about grabbing a large water tank for my ranch in Montana. How long does shipping usually take for something that big, and do they even deliver to residential places that far out?
Trying to find a coupon code for free shipping or something. Do they ever do those, or is it mostly just discounts on the site already?
