Liquid Containment Tanks
Liquid containment tanks ideal for the compliant storage of chemicals, hazardous, polluting, flammable liquids, oils and acids.
Containment tanks are essential and necessary equipment for the storage of drums, 1000-liter tanks, cans and other containers of polluting and dangerous liquids for people and the environment.
Sall offers safety tanks in both steel and plastic (such as those in modified PVC which are exclusive Justrite materials, always purchasable at Justrite Italia) in various sizes, versions, materials and with different capacities in litres in order to ensure storage in compliance with the law and in maximum safety for any of your needs and types of liquid.

What Are Liquid Containment Tanks and When Are They Needed?
Liquid containment tanks, also commonly called collection tanks or safety tanks, are secondary safety containers made of steel or plastic that serve as a safety containment system for primary containers.
The tanks are typically composed of a watertight tank, with a square or rectangular base, on which a self-supporting and removable grating is positioned.
The grating forms the support base for the primary containers, usually drums, jerry cans and IBC tanks, and the underlying basin serves to contain any leaks, drips and spills of liquids that may occur both during filling or emptying operations and in the event of breakage or damage to the primary containers.
Collection tanks are therefore necessary for the safe and compliant storage, both in external and internal environments, of all primary containers of dangerous and polluting liquids.

What Types of Collection Tanks Are There and How to Choose the One You Need?
Liquid containment tanks are made of either steel or plastic materials.
We commonly tend to choose the steel tank for the storage of dangerous, polluting but non-corrosive substances and the plastic collection tank for even highly corrosive acids, but is this really the case?
Le steel tubs Sall can in fact be equipped with internal plastic lining – including polyethylene - specially selected for the storage and containment of acids or made of stainless steel. This coating makes Sall steel collection tanks the best choice in terms of safety, durability and resistance even for highly corrosive acids by combining the advantages of the steel structure with those of polyethylene, or other plastic material, as regards corrosion resistance properties.
Stainless steel tanks are suitable for holding a wide variety of liquids and chemical substances, including acids.
The choice of stainless steel collection tanks, produced by Sall on request, is in fact typically the first choice for companies operating in the food sector or in the chemical-pharmaceutical industry.
So when is a plastic tub needed?
Le plastic collection tanks they exist instead in the versions standard o folding e portable. Plastic tubs have the advantage of greater lightness and can safely contain acids, alkaline substances, pollutants e dangerous ma non-flammable. Polyethylene tanks can also be moved with a forklift and, like all plastic tanks, do not require anti-rust treatments. Substances for which plastic collection tanks are usually used: boric acid, hydrochloric acid, phosphoric acid, formic acid, chloroacetic acid, potassium acid, engine oil, alkaline substances (bases).
As mentioned above, however, the choice no longer depends only on the type of liquid, as stainless steel tanks or tanks with internal polyethylene lining are also ideal for acids, but also on the type of use and the industrial sector.
Types and Uses of Steel Containment Tanks
- Steel containment tanks: the steel versions galvanized o varnished They are suitable for internal storage of dangerous, polluting and flammable substances and can be moved empty with a forklift.
- Stainless steel containment tanks: particularly suitable for the sector feed e chemist pharmaceuticals as for the containment of chemical, dangerous, polluting, flammable substances e acids. Movable with forklift and suitable for internal storage. Available on request for both standard models and according to customer specifications.
-
Steel collection tanks with internal polyethylene lining: recommended for acids, corrosive liquids e bases. Thanks to the durability and resistance of the steel structure, they allow for a medium/long-term return on investment costs. They can also be moved empty and with a forklift.
Available on request for all standard models and for custom-made safety tanks.
Types and Uses of Plastic Liquid Containment Tanks
- Collection tanks made of polyethylene or other plastic material: allow to minimize the initial investment costs, have the advantages of greater lightness and are suitable for polluting liquids, dangerous substances, acids, alkalis but not for flammables. Can be moved with a forklift or empty pallet truck. – Available on request.
-
Universal portable containment tanks in modified PVC BC: are the always ready-to-use solution and allow the maximum flexibility of use. Thanks to their extreme lightness and resistance and the exclusive Justrite BC materials, they are ideal for all emergency situations where you need to act immediately, effectively and quickly.
In fact, they can be effectively used as a base for portable emergency showers in emergency situations, containment tank in case of spills with tanker trucks, containment of IBC drums, cans, and in general, in all occasions that require an effective, practical to use, ready-to-use, flexible and portable liquid containment solution.
Available in both high collection volume versions that can be driven on by heavy vehicles, such as trucks, and in flexible and transportable versions, even by hand. They are ideal for drums, 1000-liter tanks, cans, equipment that can cause leaks and much more.
Trolleys with collection tank
- Mobile collection tanks: these are drum trolleys with an integrated collection tank.
Made entirely of galvanized or painted steel, they can also be accessorized with an internal lining of the containment tank in polyethylene, or other acid-proof material.
This type of tank is required for the transport of 200 litre drums and other smaller containers to prevent spillage risks during the handling of primary containers and can also be used for the temporary storage of hazardous liquids.
They allow for practical and easy manual handling even in tight spaces thanks to the compact Sall design.
The continuous updating of the regulatory framework for environmental protection and occupational safety sometimes makes it difficult to clearly understand the applicable standards for the industry, the substance and the safety guidelines.
Just to name the most well-known ones like REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations, EPA (Environmental Protection Agency) regulations, SPCC (Spill Prevention Control and Countermeasure), OSHA regulations and guidelines, it is clear that this is a very specific issue that needs experts to guide you through.
Furthermore, each European country has its own regulations, such as the Italian regulation or the StawaR directive for Germany.
We always recommend that you check the regulations in your country and contact Justrite experts so that they can guide you through this intricate process and you will be sure to get the most effective and compliant solutions.
Current Regulations for Containment Tanks and Calculation of Capacity in Liters
Legislative Decree 19.05.1999 n°152 for the protection of water, subsequently amended by the subsequent Legislative Decree 2000 n. 258, establishes that the minimum capacity in litres of each containment tank must be: equal to the volume of the largest container stored and in any case never less than 1/3 (equivalent to 33%) of the total volume.
Attention: if the storage of polluting and hazardous substances takes place in a area di protection of the water table then the tub di collection must have a capacity equal to the entire stored volume in litres (100%).
Let's make an example:
It is necessary to store 2 drums of 200 liters, 1 can of 30 liters and 1 other drum of 60 liters. The total stored 490 liters and therefore 33% of 490 liters is 161,7 liters.
Now, however, since the largest container stored is the 200-litre drum, the tank will necessarily have to contain no less than 200 litres to comply with the regulation.
For mandatory regulations in other countries, it is always advisable to check with the competent authorities or request a free consultation from Sall experts.
