Hello,
We have purchased a house built in 1910.
The basement is completely dry, which is already a positive sign.
In the basement, there is this opening, fully tiled except for a 2 cm (1 inch) gap where a gravel bed is located. The water inside is also very clear. What could this be? According to the seller, the water has always been used for irrigating the garden. I’m concerned that it might overflow since there is no pump or similar system installed.
The building is situated on a slope, and one side is only 0.5 m (20 inches) below ground level. It should therefore be considered a high basement.

However, I myself do not know where the yellow corrugated pipe comes from, and neither does the seller.Or could it be that the house has drainage at the sides, which is directed into the basement at the lowest point? This would make sense if it leads into the house opposite the hillside side.

According to the seller, the water was always used for garden irrigation. I am just concerned that it might overflow since there is no pump or anything installed.
The building is located on a slope, and one side is only 0.5 m (1.6 feet) below ground level. So, it should be a raised basement.

It is a sump pit. Why it was built doesn’t really matter, as long as the sump does what it’s supposed to, which is to drain water.
I had one myself under my basement, but mine had a pump and was covered. The water there was soapy; I wouldn’t have wanted to use it.

The neighbors’ houses do not have this.
