Good evening,
according to the zoning plan, a cistern must be built on the property. The drainage is carried out via a separate system.
So, two manholes and a cistern are required. From a technical point of view, is it possible to combine the rainwater inspection chamber and the cistern into a single structure to save some effort, or can I skip calling the authorities?
Thank you

Gartenfreund4 Apr 2022 06:51Here is the policy we follow.
Rainwater, also called stormwater, that is collected from roofs, driveways, etc., into a cistern and then used for garden irrigation or allowed to infiltrate on the property does not require any stormwater fees to be paid.
I had to look it up online because we have not paid stormwater fees for several years now.
The fee here is 1.36 euros per m² (10.8 sq ft) of sealed surface area per year.
If the cistern is connected to the sewer system, then half of that amount must be paid per m².
And as mentioned, if the cistern is not connected to the sewer but ensures that rainwater infiltrates exclusively on the own property, no fees are charged.
A meter is also not required.
If you want to use rainwater inside the house, a meter must be installed so that the rainwater, which then becomes treated water, can be properly billed.
Personally, I regret that I could only install a 4 m³ (140 cu ft) cistern underground.
If possible, choose a large cistern.
