ᐅ Irrigation with a well – too much for an area of about 650 m²

Hello everyone,
First of all, I want to apologize for not sharing the house building process with you in my other thread. Time flew by incredibly fast, and we moved in already in October 2021. So far, the construction went smoothly, and we now want to start working on the garden in May. Specifically, it’s about irrigation using a well. I have read other threads and I’m completely overwhelmed trying to figure out if the pump we had installed is even sufficient for our property, and if so, how we should plan the system.
Can you help me get started with the planning? This is the current situation:
Groundwater at around 2 m (6.5 feet). Drilled well about 7 m (23 feet) deep.
The installed pump is:
iWater eco3 4-60 62 m (203 feet), 3.6 m³/h (includes pressure switch, dry-run protection etc.)
Connected with PE pipe, 32 x 3.0 mm (1.25 x 0.12 inches)
I’ve attached a drawing of the current installation. The plan is also to use the well water for 2 toilets, the washing machine, and 2 outdoor water outlets. The installation can be expanded inside the garage if needed. Attached is also a site plan, with the paved areas marked in gray and the planting beds in green. The backyard will initially be fully lawn for the next few years.
As a complete beginner, I thought I’d simply take the 35 mm (1.38 inch) pipe and put enough rotators on it to cover the entire area. Now, after reading other threads, I’m struggling to imagine how we can do this with the current pump capacity. The initial plan with one zone (as intended) would require a total of 11.83 m³/h, but my pump can only deliver 3.6 m³/h. If I understand correctly, I’d have to split it into 3 zones, right?
These are the rotators I’ve planned so far. This leaves some gaps in the middle — is it acceptable to leave these and hope the water reaches there somehow?
11 x MP 3500 (10 m (33 feet) radius, 180°) 8.22 m³/h
4 x MP 3000 (9.1 m (30 feet) radius, 360°) 3.30 m³/h
6 x MP 800 SR (3 m (10 feet) radius, 180°) 0.31 m³/h
As soon as I need multiple zones, the pipe entry probably won’t be sufficient anymore. I’ll have to try to get 4 x 35 mm (1.38 inch) pipes through the KG pipe. Mathematically that should work… Otherwise, the zone distribution would have to be moved outside. But I’d prefer to keep everything inside the garage.
I hope you can point me in the right direction.
Thank you!

For now, only the garden irrigation is planned – the washing machine and toilets will operate normally until we know what kind of water comes from there. But are you keeping in mind that there must be two separate circuits? Well water must under no circumstances come into contact with the "regular" fresh water supply.
In this respect, it would have been sensible to carry out the water analysis BEFORE laying the additional piping.

Myrna_Loy21 Mar 2022 08:58Why does the entire area need to be watered at all?
Of course, the installation relies somewhat on the master plumber, who has installed this system in single-family homes several times before. However, I will speak with him again and ask all the questions that have come up here. Many thanks in advance!
I will revisit the planning and see how many zones I would need.

Otherwise, I have considered irrigating the large lawn area simply with a portable sprinkler. The regular irrigation system would then be planned only for the flowerbeds.
Why does the entire area need to be irrigated at all?

Is it possible to do without irrigation?If you don’t want a perfect golf course lawn, usually yes. If there’s no rain for an extended period in summer, you can also occasionally water a bit using a portable sprinkler. If you water constantly, you’ll also have to mow the lawn constantly 😉It’s a bit different with the vegetable garden, which needs more water.
And of course, you need to water regularly during the establishment phase. But you can also time the sowing to match the weather somewhat.
