ᐅ Recommendations for Garden Pumps to Empty a Sump Pit

Hello dear forum community,

Are there any recommendations for garden pumps to empty a shaft about 4 meters (13 feet) deep and approximately 1 meter (3 feet) wide? The emptying needs to be done regularly.

I am not familiar with garden equipment at all.

The pump should not be placed floating in the shaft but rather stand on a solid surface, with one hose reaching into the shaft to draw water and another hose to discharge it. At least, that’s how I imagine it.

I prefer not to buy twice and am willing to spend a bit more for a product with a long service life.

Many thanks in advance!

@Scrooge McDuck
talk to the civil engineer who installed the manhole and overflow to find out what their plan is. It’s probably all fine, and you may be able to pump garden water from there.
Also, talk to the neighbors about water, basements, and their experiences. Do you have basements?

We have a basement, including a version designed to resist occasional water pressure. All the neighbors around experienced water during the groundwork as well, but none had as much as we did.
According to the excavation contractor, the water is redirected from the spring into the shaft, so we can use it as garden water from there.

And where does the overflow go?

So, today I ran the pump for three hours. The water level in the shaft only started to drop noticeably after 2.5 hours, once the water in the excavation pit next to it had disappeared. This should indicate that the pipes leading to the shaft were installed correctly.

That’s good for now. Ask the civil engineer how they planned the shaft and the overflow. It’s possible that groundwater or seepage water is being lowered over a larger area. Is the basement slab located below the water level in the shaft?

Does your pump system operate regularly?
