Tanks are primarily categorised into two types; in-ground and above-ground tanks. Each category has advantages, drawbacks, and specific usage. There are also some similarities and differences between the two tanks. Here is everything you need to know.
The differences
Location: The main difference between in-ground and above-ground tanks is their location. An in-ground tank is buried underground and has an access shaft at the ground level. On the other hand, above-ground tanks are installed above ground level. Most units are set up on the roof or customised platforms.
Installation: In-ground tanks involve a complex installation process that involves excavation and backfilling. All these procedures require special permits from local authorities, heavy machinery, and expertise. Conversely, installing an above-ground tank is simple since the only requirement is a level surface with a solid foundation.
Capacity: In-ground tanks have a higher capacity than above-ground tanks due to the expansive underground space. Moreover, the structural demands for an above-ground tank system limit the size options.
Maintenance: Above-ground tanks are easier to maintain since they have better access for inspection and repairs. On the other hand, in-ground tanks have poor access, which makes maintenance difficult.
Cost: In-ground tanks are generally more expensive to install. The installation involves hiring labour and heavy machinery. Furthermore, the material costs are high and extra money is spent on permits. Therefore, above-ground tanks attract lower installation costs.
Environmental impact: Buried tanks have fewer environmental impacts since they are underground and are less visible. Alternately, above-ground tanks may impact the landscape and require special precautions to prevent spills and leaks.
Lifespan: In-ground tanks last longer than above-ground tanks since they are protected from the elements. Furthermore, the underground installation reduces the risk of vandalism.
The similarities
Material: In-ground tanks and above-ground tanks share material design. The most common tanks are made from steel, fibreglass, or polyethene. Nonetheless, large-capacity underground tanks have structural reinforcement.
Purpose: Both types of tanks are used for a similar purpose, storing water. They can also store fuel and chemicals. However, safety recommendations point to in-ground tanks as the ideal choice for flammable liquids and other dangerous chemicals.
Durability: In-ground and above-ground tanks are designed to be durable and long-lasting. Owners enjoy years of service with little to no repairs despite the difference in placement.
Safety: Both types of tanks require safety measures to prevent spills, leaks, and other accidents. Inground tanks have a secure ground-level access shaft that provides entry to the tank. It’s often sealed with a special lid. On the other hand, above-ground tanks have a fitted lid and sit on a raised platform to improve safety.
Compatibility: Underground and above-ground tanks share compatible components in their design and application. Fixtures like pumps and inlet pipes can be shared between the two tanks.
Regulations: Both types of tanks are subject to regulations regarding their design, installation, maintenance, and operation. The regulations ensure safety and compliance with environmental standards. Nonetheless, underground tanks face stiffer terms for installation and operation.
Despite the differences and similarities, both tanks deliver their functions. Therefore, you have the green light to invest in either or both.
