Hey Guys,
I’m looking to irrigate my lawn and am not sure how many sprinklers, zones, etc I’ll need… I’ve included a layout plan below. To explain, there’s a retained upper level (top of the drawing) and lower level with a small lawn area and then on the left of the drawing, a sloped area to the top (as well as stairs in the middle as pictured)… The lines in the middle indicate the retaining wall, stairs, etc…
The previous owners have already run water to the top level but never finished the project… So I have a 25mm pipe running from the tap that comes out where the X by the stairs is… My flow rate for the tap is 20.6 litres per minute…
Would love anyone’s two cents…
Welcome to the Bunnings Workshop community @MadDawg. It's brilliant to have you join us, and many thanks for your question about irrigation.
I've edited your image to get you started, but I'd encourage you to head to the Pope website and read through this guide on How to install an irrigation system to better understand the process.
You'll need two zones, and I've indicated them with the yellow and orange irrigation lines. The green circles indicate 1/4 spray pop-ups, the reds 1/2 and the blue full. That should give you reasonable coverage without many dry spots, though the exact placement of the pop-ups will need to be determined. They have a radius of 3.5m.
Please let me know if you have any questions.
Mitchell
