It varies, just like across the USA. Some places have low pressure and rate limiting requirements for faucets of various types, other places do not, because they have ample amounts of water.

In many places in Europe it is ironically the sewage system that actually depends on high rates of flow to function properly and retrofitting them is effectively not plausible, while also causing sewage issues because water has been made expensive, which then causes lower usage. In other places in Europe you aren’t even able to flush toilet paper because the system cannot handle it. In America, because of the nature of our development we don’t really have the antiquated sewage problem as much, but we have things like septic systems and private wells that are still widely used in places because they are so sparsely populated or even just because connecting into the public sewage system is getting increasingly financially infeasible as the financial chickens come home to roost after squandering ~$100 trillion dollars over 25 years.
