In short A 500 m² green area needs approx. 10,000 l/week, 3–4 irrigation zones each with one solenoid valve and an Ø 32 mm main line (PN10 is sufficient). Branches are made with a tapping saddle. The complete design is created by the planner or our technical consultancy.
Larger areas in garden and landscape construction need a well-thought-out zone layout and adequately dimensioned lines. This example works through a green area of 500 m² with automatic control. The exact layout is created by the irrigation planner – or our expert advisors.
Assumptions
| Parameter | Value |
|---|---|
| Area | 500 m² green/planting area (~20 l/m²/week) |
| Water source | 1″ connection, approx. 3.000 l/h |
| Control | automatic, several zones |
Result (guide values)
| Key figure | Value |
|---|---|
| Water requirement | approx. 10.000 l/week (≈ 1.430 l/day) |
| Irrigation zones | 3–4 (one solenoid valve per zone) |
| Rec. main line | Ø 32 mm PE |
| Pressure rating | PN10 sufficient (see PN/SDR) |
Parts list (example)
| Component | Quantity | Source |
|---|---|---|
| Dripline Ø 16 mm | as per planting plan | Kulano.store |
| PE main line Ø 32 mm | approx. 60 m | Kulano.store |
| Compression fitting Ø 32 + tapping saddles | Set | Connecting parts |
| Sieve filter 1″ (120 Mesh) | 1 | Plastic filters |
| Pressure reducer | 1 | Kulano.store |
| Solenoid valve 1″ + valve box | 3–4 | Solenoid valves |
For branches off the main line without interruption: installing a tapping saddle. For zone planning: solenoid valves & zones.

Frequently asked questions
How many zones for 500 m²?
Usually 3–4, depending on the available flow rate of the water source.
Which pressure rating do I need?
For this application, PN10 is generally sufficient.
How do I branch off from the main line?
With a tapping saddle – a tight branch without cutting the line.
