Hello everyone,
After building the terrace last year, we are now about to start with the lawn and some shrubs.
We are now considering whether to plan for garden irrigation.
Our old garden was much larger and we rarely watered it at all.
But now we have a southwest-facing garden, so it probably makes sense to water it to prevent damage.
We have an outdoor tap, and next to it there is a cistern water tap.
From there, a conduit runs to the lawn.
But what next?
Should we install pop-up lawn sprinklers, or just a water outlet where the existing sprinkler can be connected as needed?
Do you use drip irrigation for the shrubs?
What systems do you have? And are you satisfied with them?
I made a rough sketch, unfortunately not very good since I’m on the go. But it should give you an idea of the situation.
Black is house and garage, blue is terrace, green will be the lawn, and the dark shading is the rough plan for the shrubs.
Our lawn is about 20 meters (65.6 feet) wide and 5–7 meters (16.4–23 feet) deep.
Best regards,
Birgit

Clear water would definitely be connected, as the cistern is planned to have a pump that starts automatically when water is drawn.
If the cistern runs empty, I will switch the whole system to the house water supply.
So, I could also install the irrigation controller in the underground tank, which is planned in the area shown as the technical room in the detailed plan.
It would be a box like this:

Oh no – my mistake.
The control cable actually carries water; I was thinking of an electrical cable.
So the controller would have to be inside the valve box.
The power supply is already in the lawn area, so I don’t want to put the controller inside the house.
Either in a buried tank or next to the water tap.

I just want to install lawn sprinklers for now...Keep in mind the supply lines, as each sprinkler on the line will roughly halve the pressure. Therefore, the number of sprinklers per line is limited.
The control line carries the signal (electric current), not water.
The rule of thumb from Otus11 is not correct because the sprinklers are not arranged in series but rather with branches.
I will put this together for you in the next few days. Then you will also see how many zones there will be.

Hello Birgit,
I put it together for you. It will be even simpler and more affordable.
You will need:
5 x Hunter PRS40 housings (these include a pressure regulator)
3 x Hunter MP Rotator heads 2000, 90° to 210° (flow rate 0.18 m³/h (6.35 ft³/h) each)
1 x Hunter MP Rotator head, right strip nozzle (flow rate 0.05 m³/h (1.77 ft³/h))
1 x Hunter MP Rotator head, right strip nozzle (flow rate 0.05 m³/h (1.77 ft³/h))
Total flow rate 0.64 m³/h (22.60 ft³/h). This can easily be supplied by your water line or a reasonably good cistern pump. So one zone is sufficient.
1 x Rotator adjustment key
50 meters (164 feet) of PE pipe DN25 (depending on installation)
X fittings for branches and sprinkler connections
2 x water inlet boxes
1 x switch or irrigation controller with two outputs
1 x air pressure connection (coupling for example Gardena)
At the end of the line, you can attach a coupling (e.g., Gardena) and connect a piece of hose. This way, as desired, you can easily switch between the outdoor faucet and the cistern.
Now you can start the irrigation either manually at the faucet (or by switching on the cistern pump), or you can get an irrigation controller with water connection and two outputs (e.g., from Gardena). This means you don’t need a valve box, control cables, a “real” controller, etc.
Overall, this is a pragmatic, robust, and cost-effective solution. Since the flow rate is quite low and pressure-regulated housings are used, the pipe routing can be flexible. The sprinklers can be adjusted for range and width.
Yellow dots are the water inlet boxes (you can position them anywhere, just run the pipe there)
Yellow line is the supply line for the water inlet boxes
Black dots are the PRS40 housings (with corresponding heads)
Black line is the supply line for the sprinklers
Pink semicircle indicates the MP2000 heads, 90–210°
Blue rectangle on the right is the MP head with right strip nozzle
Blue rectangle on the left is the MP head with left strip nozzle
I wasn’t sure where your main water connection is, so I just routed it toward the utility room.
