1. Important laws and regulations 5. Approval
WHG Water Management Act
Stawa-R Steel trough guidelines
VAwS Decree on plants handling water-endangering substances (specific for each State in Germany)
BetrSichV Operational Safety Regulations
TRbF Technical rules for flammable liquids
TRGS Technical rules for hazardous substances
TRG Technical rules for compressed gases
LöRüRL Fire-fighting water retention guidelines
Existing type tests are replaced by a declaration of conformity (UHP) by the manufacturer; collection systems with a collection volume up to 1000 litres must be manufactured according to the steel trough guidelines (Stawa-R).
However, DIBt can issue general constructional approval for products that do not meet the Stawa-R guidelines and for collection systems made from plastic.
2. Specialized manufacturer as per § 19 l WHG 6. Resistance of the collection troughs
Units for the storage of waterendangering and other hazardous substances can only be manufactured and installed by specialized manufacturer as per § 19 l WHG. The overall suitability certificate as per DIN 18800 for such constructors is also required. In cases of doubt it is always correct when the collection trough is made from the same material as the container in which the hazardous substance is stored. In most cases this is 3 mm steel.
The use of stainless steel or plastic is necessary for the storage of acids and alkalis. Chemical resistance lists are useful for selecting the materials.
3. Water endangerment categories
WGK 1 Slightly water-polluting substances
WGK 2 Water-polluting substances
WGK 3 Highly water-polluting substances
4. Collection volume 7. Classification according to the Hazardous Substance Laws for liquids on which the BetrSichV is based
The collection device (collection trough) must accommodate 10 % of the total amount stored above it, but at least the contents of the largest stored container.
In water protection zones 100 % of the stored amount must be collected, assuming that storage is permitted.
