Hello

The developer recommends choosing different bricks (for an additional cost) to save on "surface water."

A simple question: what does he mean by that..............................

Good morning,

briefly explained: in many municipalities or cities, you have to pay wastewater fees for rainwater discharged into the sewer system (calculated per square meter). If you use permeable paving, you may be exempt from these fees. You would need to check whether this applies in your area and if it is worthwhile at all. The simplest option would probably be grass pavers, but there are also paving options with large joints, pores, drilled holes, and so on.

OK thanks

Now I have to ask a dumb question. Is something like this usually cost-effective compared to a "standard brick"?

That entirely depends on what the local authority charges for rainwater discharged into the sewer system...

Just ask the wastewater utility,

I can give you prices for a simple permeable paving since I recently completed a project using it. The cost was €8.25 per square meter (concrete natural color) and €10.25 per square meter (anthracite), both net prices. (Google image search "Vario Drain").
Whether it is cost-effective depends, of course, on the area, wastewater fees, and what regular paving would cost.
The wider joints also naturally provide more space for weeds to grow.

What do the written conditions in the development plan say? Is it even allowed for surface water to infiltrate the ground, or must it be directed into the public sewer system? If it has to go into the sewer, you can forget about any extra cost—unless you simply prefer the look; otherwise, for example, the standard semi-permeable pavers like those attached. In my opinion, these should not require any additional charge.

It is unfortunately not entirely correct, as my previous poster said, that you can generally be exempted. If the municipality has invested heavily in expanding its utility networks, they will strongly oppose releasing you from the obligation to connect to the sewer system. Most municipal budgets are tight; that’s why they often resist infiltration solutions like soakaways.
