Hello everyone,

We are now looking to activate our (construction) water supply on the property.

For this, we want to use the existing (old) well. It was reportedly still in use "until recently." It consists of a pipe in the ground within a pit. There is a tap at the top. The pump and the connection (we thought simply a flexible hose) to the tap are missing.
The property is just under 1000m² (10,764 sq ft). The well will only be used for garden irrigation. The house water supply is connected to the municipal water system.

Which garden pump / well pump would you recommend? We are currently leaning toward the classic turquoise/light blue brand typically used for gardens. How should the pump be sized? Is it possible to leave the pump installed during the winter, or does it need to be removed because of frost?

Thank you very much for sharing your experience.

Best regards to all.

Photo?
What kind of pipe is that?
We also have an old well, but it was about a DN110 pipe. A submersible pump was lowered into it...

So, submersible pump or suction pump?

You can use a simple submersible pump.
Whether it’s from Gardena, Güde, or Aldi doesn’t really matter for private use.
If it’s only for irrigation, the flow rate is secondary. You need to pay attention to the delivery height; standard submersible pumps have around 5 to 8 meters (16 to 26 feet) of delivery height. The cable is usually about 10 meters (33 feet) long. For a dry power connection, you can use, for example, a safety box for Schuko plugs.
I would design the outlet above the well without a faucet. This way, the water column can drain back after turning off, which prevents the hose from freezing. It’s even better if the line to the outlet is flexible. The pump can simply stay in the water.
You need to create a way to turn the pump on and off next to the outlet.

Oh, right... definitely a submersible pump.
I don’t know how deep the drilling is or where the groundwater level is. I might get that information from the geotechnical report.

I need to take a photo of the pipe. Photo will follow. Now I'm not sure anymore. Is the difference only in the pipe diameter? So whether it's a suction or a submersible pump.

Well, using a DN110 pipe and a submersible pump with a float switch won't work.
