Hello everyone,
I visited a landscaping company today, and they told me about separation stations. Apparently, since 2021 it is only allowed to water gardens with a separation station when building new properties.
Until now, I knew that, for example, outdoor taps can be connected directly to the water supply near a toilet or sink.
What are your thoughts on this?
I don’t like the separation station (with a pump): electricity costs, maintenance...

Outdoor taps usually have an air admittance valve or backflow preventer. This is a completely standard drinking water installation (see rick2018).
So, once again, the question: What kind of installation do you mean?
I once read that the outdoor tap pipe line should best be installed in a loop or directly at a point where water flows frequently (supply line for toilet cistern, kitchen, etc.). Only in this way is water circulation ensured, preventing bacteria from developing in the water.

With a separator, it doesn’t matter. You branch off wherever it is most practical. Just don’t declare it as drinking water or let it run for a while. In the past, we also drank directly from the garden hose and survived.

I want to build without a separator. The question is whether it is mandatory for new buildings (from 2021 onward).

That has actually been mandatory for much longer.
