Single or two-family house with a hole in the basement

Go to elwas web, enter the address there, then click on Oberflächengewässer on the left and then on OW Hochwasser. There you will find the tabs HWRM-Rücklauf Gefahrenkarte and Überschwemmungsgebiete. Check the high and medium probability in HWRM-Rücklauf; the low one, I think, occurs every 100 years. And take a look at the designated Überschwemmungsgebiete. This way you can see if you are in the danger area.

HI Thanks for the tips,

I have received or asked the following questions (and answers) from the owner.

--> No, the drainage is connected to the sewer.

--> Not exactly known, probably a spring or from the nearby stream.

--> No

--> The water is discharged via the gutter connection, the inspection shaft is located in front of the house.

--> The spot is known, but nothing more.

--> Yes, it is insured

What do you think? Problematic altogether? I definitely wanted to go in with a building surveyor next week.

But could this water be intercepted and diverted from outside?

Have you ever asked the neighbors about the [Bach]???

Yes, according to the neighbors, the stream is not a problem and it does not flow extremely. The neighbors have no problems with the stream or a spring under the house.

We had exactly such a hole in our ERH. Discovered only after purchase. The pump switched on about twice a year. After about 10 years it was defective once and was replaced. Yes, life is probably more relaxed without such a hole, but it can always happen that such an infiltration shaft has to be dug. It was certainly not planned during the house construction, but later necessary. By the way, the basement was always dry.

Thank you. Did you also have slightly running water in the hole? Where did you drain the water to?
