Construction
Done in just a few days
The Börger stainless steel tank consists of individual segments (1.50 x 3.00 m) which are bolted to one another.
Joined together horizontally, the individual plates are stabilized by the peripheral U-profile. The cylindrical tank is constructed, attached and permanently sealed onto a smooth flat base plate.

The suitable stainless steel for each application
To be able to build a tank which is perfectly suited for any type of stored liquid, we offer our stainless steel tanks in various materials.
High-quality stainless steels and solid wall thicknesses guarantee a long service life along with maximum lasting value while giving you peace of mind knowing that you have opted for the right tank.
Always the best solution
Thanks to various capacities, materials, roof variations, mixers and other attachment parts, Börger tank systems can be designed such that they are perfectly suited for your application:
• Process water tanks
• Sludge tanks
• Liquid manure storage
• Aeration basin
• Biogas fermenter or final storage
• Digestion tower
• Storage for liquid feed or moist cereal
• Fire-extinguishing water storage
• Liquid fertilizer storage
• Storage tank for liquids of any type
• etc.
The stainless steel tank with DIBt approval
Börger stainless steel tanks have the DIBt approval for JGS systems The German Institute for Building Technology (DIBt) has granted us DIBt approval for liquid manure/slurry silage (JGS) systems.
Benefits:
• Simplified granting of a building permit
• Prerequisite for applying for state subsidies
• Pre-designed and regulated expert inspection
• Regulated leakage detection system
• Tested construction system
• Sealing system tested for durability
• Use of various approved sealants
Background:
The new “Storage Ordinance for the Handling of Substances Hazardous to Water” (AwSV) came into force on August 1, 2017 and serves as the basis for approval procedures for slurry storage tanks. It applies nationwide and has replaced the previous state-specific regulations. In this context, it was stipulated that only approved components, construction systems and container systems may be used for the construction of storage facilities for JGS. After a lengthy process with many individual tests, the DIBt granted us DIBt approval in 2021 as the only manufacturer of steel and stainless steel containers to date.
Case Studies
Practical example
Whether it's in industry, wastewater treatment, agriculture or biogas – Börger stainless steel tanks are stable in value and maintenance-free solutions for storing liquids.
The industries and applications listed here will give you an impression of the versatility of Börger stainless steel tanks.
Wastewater for MAP precipitation
A wastewater treatment plant was looking for suitable tanks for the precipitation of magnesium ammonium phosphate (MAP) from municipal digested sludge.
Phosphorus is recovered during this chemical process. The customer opted for two Börger stainless steel tanks. They were convinced by the variety of possible stainless steel qualities and the consulting offered by Börger. Following a thorough analysis of the digested sludge composition, the suitable stainless steel and sealant were selected. Thanks to the segmental design, the tanks could be set up very quickly.
They are equipped with an insulation and a multi-colored trapezoidal sheet cladding. The gas-tight stainless steel roof protects the environment from emissions. The 1 m x 2 m (3.2 x 6.5 feet) pressure doors allow the customer easy access to the emptied tanks.
Leachate
The operators of a landfill were looking for suitable tanks to store the leachate occurring in the plant. The PE tanks used so far had become too small.
The customer opted for three Börger stainless steel tanks. Depending on the rainfall, different amounts of leachate with varying pollutant concentrations occur at the landfill. The stainless steel tanks are lined on the inside with HDPE sheets to protect the stainless steel from the often highly concentrated pollutants. The plastic sheets could be fastened without any problems to the horizontal screw connections.
Thanks to the self-supporting roofs, a roof support was not required, which made laying of the flooring material so much easier. The semi-annual inspections can be carried out quickly and easily through the manholes in the tanks.
Liquid manure storage
For the storage of liquid manure, a farmer opted for two Börger stainless steel tanks with a capacity of 2,528 m³ (11,130 usgpm/h) each. By using two storage tanks the farmer is able to reduce the content of phosphorus in the liquid manure by means of a special sedimentation process.
In addition to the high quality of the Börger tanks the customer was convinced in particular by the lasting value as well as the option to increase the capacity of the tanks later on.
Due to current legislation the tanks were equipped with a roof for emission protection. For tanks without a roof retrofitting is possible anytime with ease.
Fermenter
The operator of a biogas plant was looking for three new tanks for the facility. They were to be used as a beet store, a fermenter and final storage tank. The tank for final storage needed to have a volume of 5,000 m³ (22,014 usgpm/h).
The customer opted for three Börger stainless steel tanks. The customer was particularly impressed with all the options available for Börger stainless steel tanks. The customer could select the perfect solution for his requirements from the wide range of different covers. The plan is to extend the beet tank from the current storage capacity of 1,895 m³ up to 2,527 m³ (8,343 - 11,126 usgpm) in 2015.
The stability of the stainless steel tank and the option of dismantling it to assemble in another location gave the operator of the biogas plant financial security should the guaranteed payments for power feed into the power under the terms of the German Renewable Energy Act end after 20 years.
