Hello everyone,
We are currently working on building our single-family house. The building application has been submitted, and we promptly received the first letter from the building authority stating:
Rainwater must generally be infiltrated or directed into a nearby open water body, as long as this is possible without excessive effort and damage (§ 48 b Abs. 3 WG-BW).
After a phone consultation with the building authority, we were told that rainwater is not allowed to be discharged into the sewer system due to water protection zone III. The proposed solution (if you can call it that, as they basically said “there’s no way around it”) is a cistern. Permeable paving was also mentioned for the driveway, although we’re not sure what that is for. There is no water body nearby, by the way.
We had actually considered a cistern for watering the garden but excluded it due to the cost. Now we are being forced to install one despite the financial strain, so I have a question for you.
There seem to be countless types of cisterns (according to Google). Can you tell me which type would suit our purpose and where it’s most important not to cut corners?
Kind regards

No, it's not the pipe that costs that much! The labor costs 100 € per meter, including the pipe.I understand that already 😀 excavation, laying with slope, sand bedding, and so on. Still, quite a steep price for half a day's work with two people and a mini excavator.

Still, a steep price for half a day’s work with two people and a mini excavator. These are the typical prices here around Cologne at the moment.
I have had to pay much higher amounts for far less work before,
but you can’t avoid it!

You can probably rent a mini excavator for about a hundred,
3,000 net for a Saturday is an acceptable hourly rate even for all the contractors, doctors, and lawyers around here.

and everything is going haywire because everyone assumes they can do it better and cheaper themselves.
I prefer to plan more generously from the start, so I don’t face any surprises and have an invoice and warranty for everything.
It starts with digging the hole—can you handle transporting the 5 twin-axle truckloads of soil to the disposal site?
Are you assembling the soakaway system professionally? You get those delivered as parts to be put together!
I can reassure you, this was neither done by us with two people in two days, nor by the neighbors with their civil engineers!
