Hello everyone,
As the name suggests, I am looking for a good solution to prevent the groundwater from rising unnecessarily high or to stop the light wells from flooding. We installed a 30cm (12 inch) pipe. I tried using a float switch, but when it’s at the bottom, it tends to get stuck and doesn’t rise again. As a result, the pump doesn’t activate. Are there any other or better options?
We’ve had a lot of rain recently, although that won’t be the norm. We wanted the pipe to use the groundwater for watering. Now I’m actually glad to be able to pump it away.
I have now positioned the float switch higher and connected a timer.
Good luck

We have a similar setup in our old house.
The drainage pipe was wrapped twice in geotextile fabric before burying it, and we poured a bucket of concrete on top as a base.
It has never become as clogged as it did in your case over 25 years, and the float operates in clear water.

It never got as muddy as in your case over 25 years, and the float switch works in clear water. We are currently in the middle of the shell construction... I should have mentioned that earlier. I am more concerned about a future solution. There is no mud buildup, the water is quite clear. We do not have any drainage system (if that matters).
Due to the groundwater, we have a waterproof concrete shell and have placed the vertical pipe 10cm (4 inches) close to the house without additional drainage.
During heavy rain, the pump runs about every 10 minutes; in dry years, it does not run at all.
The pump discharges into the downpipe, which is connected to a cistern (for irrigation water) with an overflow.

So we’ll probably do it the same way. Do you basically not use the “groundwater/well water” separately? Only the water from the cistern? Is your pipe diameter also 30cm (12 inches)? I think a permanent pump should simply be properly installed. This was more of an emergency solution, I would say.
There are also submersible pumps without a float switch (e.g., Gardena Aquasensor; similar technology is available from all major competitors). Alternatively, you can install an external switch (reed, capacitive, or float “on the rod,” etc.) and position the submersible pump lower than the switch to control it that way.
