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

Created on: 9 Sep 2020 14:49

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?

The reason for choosing DN63 was that a pool is planned in the medium term at the end of the pipe, but DN32 should be sufficient for refilling there as well.

DN25 is sufficient. Depending on where you install the equipment, for example inside the house, you can also refill it there.

Okay, thanks for the information!

Since the irrigation will probably be DN32, that works. So only one type of pipe needs to be installed.

When I use the T.I.P. AJ 4 Plus 100/57 AUT, what flow rate and length can I achieve in the loops? Is there a rule of thumb for this?
