Above Ground plastic Water Tanks
Above Ground, HDPE Plastic 

Benefits of Above-Ground Tanks

  1. Cost - Above ground tanks cost approximately 40% less than below ground tanks.  Especially in areas of Georgia with rocky soil or high water table, above ground tanks are worth extra consideration. 

  2. Maintenance - With a properly functioning prefilter, neither tank requires much maintenance. Maybe every few years. In the past, both above and below ground tanks required confined space safety procedures. However, access hatches allowing egress through the liners are the next technological breakthrough for these tanks.

  3. Pumping - With positive suction pressure, pumps run smoother and more efficiently. Pumps can be located inside a mechanical room, safe from the environment and eliminating the need to run high voltage electricity outdoors.

  4. We should not neglect the publicity aspect of above-ground tanks. Those that want to spend the extra money on green initiatives often want their neighbors to know. For businesses, it's good business to subtly let your customers know that you care about the earth.

Challenges of Above-Ground Tanks

  1. Freeze Protection - The biggest challenge with freeze protection is not the tank itself, but any piping with sitting water. The current generation of tanks solved that problem for the most part, with piping penetrations inside the tank.  The mass of water in the tank will freeze on the surface, but it will not damage the tank. Freeze protection in Georgia can be accomplished with smart recirculation, keeping initial costs low.

  2. Aesthetics - The Great Debate among engineers: are the tanks something to hide or something to show?.  With a tank such as this in full view of passersby and customers, people will certainly know that the business owner is collecting rainwater.  As described inthis Freakanomics article, that might be very desirable indeed.  The most common colors are hunter green or black. Dura-Cast tanks are available in 14 colors, as described below.

  3. Space - The best tactic for maximizing space is to size the tank for the usage, not expected rainfall. This also reduces the cost of the project. ​​

  4. All materials are BPA-free, FDA, and NSF 61 approved for drinking water.
