Standard material S235JR; stainless steel on request. Standard with manhole DN 600; accessories such as saddle supports, additional manholes, flanges, sandblasting or top coat optional. Test certificate included. Volumes from 1 to 100 m³.
View product range →Underground Steel Storage Tanks to DIN 6608 (Earth Tanks)
Underground storage vessels – also known as earth tanks – are ideal where space is limited, for frost protection or when no visible tank installation is desired. Manufactured to DIN 6608 in two variants:
- DIN 6608/1 (single-walled) – for non-hazardous media such as firefighting water, rainwater or non-water-hazardous operating fluids.
- DIN 6608/2 (double-walled) – mandatory for water-hazardous substances (heating oil, diesel, transformer oils). Equipped with vacuum or liquid leak detector for early warning of leaks.
Underground tanks are supplied as standard with bitumen external insulation for corrosion protection. Type approval and test certificate included.
Above-ground Steel Storage Tanks to DIN 6616
Above-ground storage tanks offer easier maintenance, visual inspection and quick accessibility. Manufactured to DIN 6616 – also available in single-walled and double-walled versions:
- DIN 6616/1 (single-walled) – for non-water-hazardous media. Externally primed or with top coat.
- DIN 6616/2 (double-walled) – with vacuum monitoring for water-hazardous substances under WHG (German Water Resources Act). DIBt approval on request.
Above-ground tanks are mounted on saddle supports (optional) and can be combined with a containment bund. Surface optionally primed, sandblasted or with top coat.
Standard Comparison: DIN 6608 vs. DIN 6616 vs. EN 12285
The historical DIN standards 6608 and 6616 have been superseded by the European EN 12285. In practice, the DIN designations remain widely used.

Storage Tanks for Heating Oil, Diesel, Firefighting Water & Transformer Oils
Our DIN-compliant steel storage tanks are suitable for a wide range of media. The DIN 6601 positive list defines all approved liquids for S235JR steel vessels. Typical applications:
Heating oil (DIN 51603)
Diesel fuel
Firefighting water (DIN 6608/1)
Transformer oils
Motor gasoline
Hydraulic oils
Methanol & solvents
Vegetable oils & biodiesel
WHG-compliant versions for water-hazardous substances
For the storage of water-hazardous substances (water hazard classes 1, 2 and 3), a double-walled design with leak monitoring is mandatory under WHG (German Water Resources Act). Our DIN 6608/2 and DIN 6616/2 storage tanks meet this requirement and are supplied with test certificate. A DIBt approval (German Institute for Building Technology) is available on request.
Detailed information on WHG requirements and hazard classes can be found in our Guide: WHG Vessels for Water-hazardous Substances.

Installation Checklist: What to Consider Before Tank Installation
From needs analysis to acceptance testing – these six steps help plan your tank installation.
-
1
Needs analysis
Define storage medium, required volume and installation location (underground/above-ground). A double-walled design is required for water-hazardous substances.
-
2
Standard selection & configuration
Choose DIN 6608 (underground) or DIN 6616 (above-ground). Coordinate wall construction, diameter and accessories (saddle supports, flanges, manholes) with us.
-
3
Check permits
Clarify WHG/AwSV requirements. Underground: obtain building permit and soil survey if required. Above-ground: observe containment bund requirements and clearance regulations.
-
4
Site preparation
Underground: excavate pit, prepare sand bed, check groundwater level. Above-ground: dimension and construct foundation or containment bund.
-
5
Delivery & installation
Delivery by low-loader, positioning by crane. Professionally install connections, ventilation and leak detector. Filling only after acceptance.
-
6
Acceptance testing & documentation
Carry out leak test. Archive test certificate, type approval and DIBt approval if applicable. Schedule recurring inspection under AwSV.
Approved Media per DIN 6601 / EN 12285-1 (Positive List)
Media compatibility notice: The listed media represent an extract from the compatibility list per DIN 6601 / DIN EN 12285-1, Annex B and do not claim to be exhaustive. Suitability for a specific storage medium depends on additional factors (including concentration, temperature, mixed media). Please contact our technical team for a project-specific assessment. Only the specifications stated in the quotation or order confirmation are binding.
