ᐅ Rainwater Harvesting Cistern for Garden Irrigation – Which Pump Should I Use?

Greetings!

I am gradually starting to plan the garden irrigation for my soon-to-be-completed house. For now, I want to keep it simple and non-smart: a cistern (6,000 liters) is installed underground, and I plan to water the garden conventionally using a pump and garden hose. The farthest lawn area will be reachable with about 35 to 40 meters (115 to 130 feet) of hose length. The cistern is located at the lowest point, about 2.50 meters (8 feet) underground.

Now I am facing a confusing variety of possible pumps: suction pump, dirty water pump, submersible pump, garden pump, deep well pump... several thousand liters per hour, various pressure ratings in bar... Does anyone have good advice?

Ok. So the filter should be installed more on the pressure side. Any recommendations on which filter to use? And to protect the cistern from dirty water, would simply attaching a filter basket to the inlet be sufficient?

I believe I have understood everything reasonably well so far.
I will lay the PE-HD pipes before graveling the area for the terrace and route them to the respective locations, correct?

I personally know of three installations using the Tipp (AUT). They have been running trouble-free for years.
Yes, the pipes need to be installed underground. Do not use Gardena valves! Use PE-HD pipes for drinking water or PE100 pipes.
Lay them under the terrace and have them come out at the top.

Diameter of the pipe/hose? Probably 25mm (1 inch)?

Better to use DN32. Less loss. The price difference is almost negligible.

Difficult question regarding the pump. Globus DIY store offers a best price guarantee, so I will inquire further about the details. If you could get it there at the usual market price of 320€ (about $350), that would be good. Plus, there would be a 7-year Globus warranty.

The more I compare the Tipp AJ 4 Plus 100/57 AUT and the Oase ProMax Pressure Well Automatic 6000/8, the more they seem almost identical. Both in terms of technical specifications and appearance. I could almost imagine they come from the same manufacturer. But I have no idea who produces what here.
