Above Ground Rainwater Tanks

Pros

Above ground, tanks are, on the whole, cheaper. This is because they are easier to install, typically requiring no excavation. Aside from this well-known benefit, there are other advantages, including easy maintenance – as the tank isn’t buried it offers easy access when troubleshooting is required, or when repairs need to be made; design options, as above-ground tanks can be decorated and camouflaged to blend in with their surroundings, or made more obvious to highlight your green credentials.

Cons

Above ground rainwater tanks are exposed to the elements, which carries a higher risk of damage from weather or fire. There is also the concern of vandalism and the chance that damage may lead to leaks. These are the kind of worries which can be addressed with regular inspections. Temperature can be harder to control, with water freezing in the winter and getting very hot in summer.

Underground Rainwater Tanks

Pros

Underground tanks, also known as in-ground tanks, are excellent for economising on space – their low profile means that you can retain more space above ground, where real estate is at a premium. The space that you save can be used for a range of purposes; from a garden to a driveway or lawn. This low profile can also negate a large visible structure, with only a limited amount of piping being seen with the naked eye. Because a below-ground water tank benefits from superior insulation, they can be protected from the cold and heat, and therefore the temperature is easier to regulate.

Cons

The higher cost is a factor that will dissuade many from opting for an underground tank. This is due to the installation, which usually requires excavation, and the reinforcement of the tank, as well as putting in a pumping system. Being underground, it is also harder to maintain, and you should ensure that the type of soil on your site is suitable for a tank. Soil that contains a high volume of clay may not accommodate tanks.

As you can see, there are a number of facts to bear in mind when selecting rainwater harvesting tanks above ground or beneath the soil. Take your time and consider all factors.
