An above ground storage tank are those tanks that are constructed above grounds. For the case of water tanks they are mostly situated on top of buildings if they are small but the large ones are constructed on separate grounds. The regulatory body requires such tanks to hold up to a maximum of 10,000 liters when it comes to contents other than water. There are numerous reasons for and against these tanks.
The reasons for the choice of these designs are numerous. One of these is that they are relatively cheap when it comes to installation costs because it involves fewer activities. One needs to find a space where to construct their tanks of which the only costs involved include construction of a foundation of which it is not a must for those placing their tanks above their houses. This mostly applies to water tanks. For those that require raising the grounds, less cost is involved because there is no excavation cost.
Minimal excavation is required when establishing these designs thus making it relatively cheaper. The only excavation required is for foundation only for the support. They are mostly raised slightly above while there are some which are raised high above the ground. In both situations the excavation required is very minimal slightly less expensive installation. In case where excavation is mandatory for underground tanks is in case of problems calling for repairs.
The third advantage is that they can be easily monitored. They are visible and thus the owner can easily monitor any changes which may either call for repairs. This makes this type of tanks easy to maintain and also easy to use. This also ensures there is continuous maintenance process which increases the economic life of the tanks.
In as much as these designs are considered to be generally advantageous, the do however have their own set of disadvantages. The major challenge facing these tanks is their exposure to unfavorable climatic conditions. They are exposed to excessive heat conditions during the day and too low temperatures in the nights. These diverse weather conditions promote corrosion which eventually erodes the surfaces and materials used to make these tanks. This is the major reason for the frequent bursts and leakages often experienced by the owners of these tanks.
These tanks also have their disadvantages for example they require additional space. To establish these tanks one needs to have an additional space because they cannot be constructed in open air but in a piece of land or above a building. For oil tanks they are constructed in a field and thus taking up space that could have been used for better purposes. Unlike with underground one cannot use the same space for two purposes because when set up, that space is completely out of use.
They are also affected negatively by adverse weather conditions such as too much solar or high temperature conditions. Such conditions may result to corrosion of the tanks and in other situations they may even cause them to burst especially in the case of plastic tanks. For one to avoid such situation it means construction of a structure that will protect the tanks from such effects. This will call for additional costs which will make the whole project expensive.
In conclusion above ground storage tanks have various pros and cons and needs critical analysis when deciding on their use. One will have to analyze both the advantages and the disadvantages and weigh the two so as to come up with a conclusive decision on whether to adopt it or not.
