ᐅ Cistern and soakaway pit: which pumps are suitable?

Hello everyone,

Our extension is almost finished, and now I need to take care of a few small tasks myself.

I could use some advice.

Due to the extension, we had to relocate and rebuild the cistern.
Additionally, it was noticed that water was constantly flowing into the excavation pit, even though it hadn’t rained for weeks.
For this reason, a sump pit/infiltration basin was installed about 4–5m (13–16 feet) next to the cistern.

The plan is as follows:

The drainage and incoming water flow into the infiltration basin.
This water then needs to be pumped into the cistern, where the overflow is connected to the street.

According to the local authorities, pumping directly to the street is not allowed, but going through the cistern is permitted.

We have now installed 1" (inch) PE pipe from the cistern to the garden.
The plan is to use this water for irrigating the swimming pool and the garden.

This means two pumps are required.

The pump in the infiltration basin should pump continuously as the water level rises, while the one in the cistern should maintain constant pressure in the water line to the garden.

Which pumps would you recommend for this setup?
I would also prefer to avoid float switches and instead use installed level sensors that can alert me in case the pump in the infiltration basin fails.

Thanks for your input.

Take a look at the Tipp pumps.
Good value for money. Especially suitable for irrigation since they provide enough pressure and flow rate.
They are also tolerant of dirt. Available without pump control and float switch so you can control them externally.
Let me guess, you check the pool levels with test strips? Just because it’s been done that way for a long time doesn’t mean it’s correct. But if you have no issues, then that’s fine.


The pumps are already on site.

and for the soakaway




Pump Ebara Best ONE M with 10m (33 feet) cable


These will be connected directly to the PE (polyethylene) pipe and then routed to the garden.

Yes, the water quality is monitored using test strips.

Just as a note. Try a shake test or, better yet, a testing device. I'm quite sure the values are not optimal. Great if it works out well with the pumps.
