Why a underground tank?
A underground tank is a storage tank that is installed below the ground surface. These tanks are often used to store liquids such as fuel, oil, chemicals, water and sewage. Underground tanks can be single-skinned or double-skinned, depending on the requirements for safety and environmental protection.
Features and Benefits of UndergroundTanks
- Space saving:
Underground tanks save space on the surface, which is an advantage in places with limited space, such as urban areas and commercial properties. - Security:
By placing the tanks underground, the risk of fire and explosions is reduced, especially when storing flammable liquids such as petrol and diesel. - Environmental protection:
Modern underground tanks, especially the double-skinned ones, are designed to prevent leaks and minimize the risk of soil and water contamination. With a properly installed double-skinned underground tank, there is a very minimal risk of leakage. - Aesthetics:
Underground tanks are hidden from view, preserving the aesthetics of the surrounding area, such as in residential areas or commercial locations. - Temperature regulation:
The soil acts as a natural insulator, helping to keep liquids at a stable temperature, which is important for certain chemicals and fuels.
Types of Underground Tanks
- Single-skinned tanks:
Has only a single container (tank wall) and is usually cheaper to manufacture. However, they require extra protective measures to prevent leaks. - Double-walled tanks:
Consists of an inner and outer wall with a gap that can be monitored for leaks. This provides extra security against leaks and contamination.
Areas of application
- Fuel storage:
Used by gas stations and commercial facilities to store gasoline, diesel and other fuels. - Water supply:
Used for storing drinking water or rainwater for later use. - Waste water management:
Used for collecting and storing waste water until it can be treated or transported to a treatment plant. - Storage of chemicals:
Industrial facilities use underground tanks to store chemicals in a safe and controlled manner. - Depot facility / Tank facility:
As a safer alternative to storage facilities above ground, with large space-built tanks. More and more storage facilities are built today with batteries of underground tanks. It is especially with a view to the risk of fire/explosion that it is a big advantage to have underground tanks. However, it also provides more flexibility and less challenges with temperature fluctuations.
