They prevent leaks and spills
Double-walled fuel tanks are an effective way to prevent leaks and spills. They are designed with two walls and a gap, or interstitial space, between them, providing an additional line of defence. This secondary containment system offers several benefits over single-wall tanks, which have only one layer for fuel storage.
The inner tank in a double-walled design is where the fuel is stored, while the outer tank acts as a containment tank, providing an extra layer of protection. This outer tank prevents spills or leaks, ensuring that fuel remains securely contained even if the inner tank is compromised. This two-wall design also adds durability, as the inner tank is protected from impact and the elements by the robust secondary tank and cavity.
The interstitial space between the two walls is a critical feature for leak detection. Sensors can be placed in this space to detect leaks early, minimising the risk of environmental damage and reducing the likelihood of injury. When choosing a sensor, it is important to consider the type of liquid being stored, the environment, and the desired sensitivity. For example, a chemical storage tank may require a highly sensitive sensor to detect small leaks, while an oil storage tank may need a sensor that can withstand harsh conditions.
Double-walled tanks also offer cost savings by eliminating the need for secondary containment pans, berms, and basins. These containment structures can be costly to maintain and clean, especially when they fill up with rainwater and debris. By removing the need for these additional structures, double-walled tanks simplify maintenance, tank cleaning, and inspections, resulting in long-term cost savings.

They are used in chemical, oil and gas, and environmental management industries
Double-walled tanks are widely used in the chemical, oil and gas, and environmental management industries. These tanks are designed with two walls and a gap, or interstitial space, between them, providing an additional layer of protection against leaks and spills. This design ensures that the stored liquid remains secure even if the inner tank is compromised.
In the chemical industry, double-walled tanks are commonly employed for chemical storage. When selecting leak detection sensors for these tanks, it is crucial to choose sensors that are compatible with the specific chemicals being stored and are robust enough to withstand potential chemical reactions. The LeakPro series offers leak detection equipment that can be adapted for chemical applications, providing accurate and prompt leak detection to mitigate environmental harm.
Oil and gas companies also utilize double-walled tanks to securely store their products. These tanks are designed to prevent leaks and spills, reducing the risk of environmental damage and the associated legal costs. The outer wall of the tank acts as a protective barrier, ensuring that the fuel remains contained even if the inner tank is damaged or compromised.
Additionally, double-walled tanks are valuable in environmental management. They offer a higher level of protection compared to single-skin tanks, reducing the likelihood of spills and leaks that could harm the environment. The use of double-walled tanks can help businesses comply with health, safety, and environmental standards, demonstrating their commitment to environmental protection.
The benefits of double-walled tanks in these industries include increased durability, enhanced security, and leak prevention. The secondary containment provided by the outer wall simplifies maintenance, tank cleaning, and inspections, ultimately saving businesses time and money. Furthermore, the ability to detect leaks promptly through advanced leak detection systems further reduces the risk of environmental damage and ensures the safe handling of hazardous substances.

Sensors are used to detect leaks in double-walled tanks
Double-walled fuel tanks are designed with two layers: an inner tank for fuel storage and an outer containment tank that prevents spills or leaks. This secondary layer provides added protection, making these tanks safer, more secure, and durable. They are commonly used in businesses dealing with chemicals, oil, gas, and environmental management.
To further enhance the safety of double-walled tanks, various sensors can be employed to detect leaks promptly. When selecting a leak detection sensor, it is crucial to consider the type of liquid stored, the environmental conditions, and the desired sensitivity level. Here are some commonly used sensors for leak detection in double-walled tanks:
- Float switches: These are simple sensors that utilise a float that rises and falls with the liquid level in the tank. The float is connected to a mechanism that converts the vertical movement into a measurable signal, allowing operators to monitor the liquid level and detect unexpected drops, indicating a potential leak.
- Ultrasonic sensors: Ultrasonic sensors employ ultrasonic waves to measure the distance to the surface of the liquid. By calculating the time taken for the wave to travel to the surface and back, the sensor can determine the liquid level. Any sudden drops in the level trigger an alert, indicating a possible leak.
- Optical sensors: Optical sensors utilise a light source and a detector to measure the liquid level. The detector measures the intensity of the light reflected from the surface of the liquid. Similar to other sensors, a sudden drop in the measured level triggers an alert, suggesting a potential leak.
- Capacitive sensors: Capacitive sensors rely on the principle of capacitance, or the ability of a system to store an electrical charge. The sensor consists of two electrodes, and the capacitance between them changes as the liquid level varies. By monitoring the liquid level, these sensors can detect leaks and alert operators accordingly.
- Radar sensors: Radar sensors utilise radar technology to measure the distance to the liquid surface. Similar to ultrasonic sensors, they calculate the time taken for the radar wave to travel to the surface and back, thus determining the liquid level. Radar sensors can detect leaks by monitoring the liquid level and notifying operators of any unexpected changes.
- LevelPro leak detection sensors: LevelPro sensors are highly accurate and reliable, making them suitable for double-walled tanks. They can detect leaks in the interstitial area and provide both visual and audio alarms, enabling prompt action to prevent environmental damage and potential injuries.
It is important to choose sensors that are compatible with the type of liquid stored in the tank and robust enough to withstand potential chemical reactions. Additionally, sensors like the LeakPro series can be adapted for various applications, including chemical storage, to ensure accurate and timely leak detection.

The second wall acts as secondary containment
Double-walled fuel tanks are designed with two walls and a gap, known as an interstitial space, between them. This design serves as an additional line of defence in the event of a leak or spill. The second wall acts as secondary containment, providing several benefits over single-wall tanks.
The secondary containment offered by the second wall in double-walled tanks helps prevent leaks and spills. While single-wall tanks have just one layer for fuel storage, double-walled tanks have an inner tank surrounded by a secondary tank and cavity. This design offers an extra layer of protection, ensuring that fuel is securely contained within the inner tank.
The second wall also eliminates the need for additional containment measures such as pans, berms, and basins. This simplifies maintenance, tank cleaning, and inspections. It also reduces costs associated with purchasing, maintaining, and cleaning secondary containment equipment.
Additionally, the second wall enhances the durability of the fuel tank. The outer wall provides a robust layer of protection for the inner tank and its supporting components. This added durability helps protect the fuel from impact and exposure to the elements, further reducing the risk of leaks and spills.
Furthermore, the second wall contributes to environmental protection. In the event of a leak, the interstitial space between the walls can contain the leaked fuel, preventing it from escaping into the surrounding environment. This feature ensures that businesses comply with health, safety, and environmental standards, reducing the risk of legal costs associated with environmental damage.
