It depends.
When we talk about how THW is financed, we get about €350 million a year from the Federal Ministry of the Interior and Community as a budget for THW.
I have to admit I don't know how much money the local governments have for their organizations, like the fire brigade. If there's a disaster in the local community and it needs support from the federal government through THW, it depends. If it is small, like a truck accident, and the fire brigade is not able to support it completely and they need support from THW, there is a cost catalogue. We have to charge the local community or the local structures, but most of the time it's paid by the insurance company, which has to pay for the whole thing.
If it is a bigger disaster, like the Ahrtal flood, which I mentioned before, then most of the time the federal government says that the support from THW as a federal asset is free of cost to the requester for the communal services.
