After doing many hours of research, it's clear that if you are in the market for a Plastic Tank for Above Ground Well Water Storage, Rainwater Harvesting or Irrigation, these tanks are the way to go. Between the great BPA-Free, FDA-Approved, NSF-Approved, High Density Polyethylene material that is used, their 5 year warranty, Color options and their different assembly options, Poly-Mart Tanks are your clear choice. What puts icing on the cake is that they are locally manufactured in Austin, TX! I tried to buy directly from them but you have to purchase through one of their dealers. However, they do allow you to pick up your tank at the factory in order to prevent incurring any shipping charges. I ordered my rainwater tanks in the Light Grey color to best match the Grey brick on my house. We are really pleased with the quality. There are some cheaper tanks out on the market, but the savings of going that route is just not worth it, ask my neighbor. The rainwater version is set up to immediately & properly collect rainwater. The inferior and cheaper tanks at Tractor Supply are not and if you want to properly collect rainwater, you have to drill holes into the tank to install a large overflow & buy a inlet screen & overflow screen. Save time, hassle and money and get a Poly-Mart Tank! read more
