How To Plan A Garden Irrigation – DIY At Bunnings


I’m going to be showing you how to plan your
irrigation system. For the first part you’re going to need a few different tools. I’ve
got my bucket, a tape measure, a ruler, a pencil, my phone, and also some grid paper
to plan my garden. Now I use this as a one centimeter square equals one meter in my garden.
So the first step in planning our irrigation system is to first roll measure your garden.
Simply just measure by the meter and pop down in your grid paper remembering that one square
equals one meter in your garden. Now when drawing your map, make sure you put in any
obstacles, such as here I put in a tree which is in the middle of the lawn. This will help
you better plan our irrigation system. Now that I’ve written down and taken measurements,
I can now plan how many meters of poly-tube I’m going to need to lay my irrigation system.
At this point in time depending on the plants you have you can decide if you want to put
in pop-up sprinklers, a drip-line system, or sprayers depending on the different plants
that you do have in your garden bed. This can now be pinpointed on your map if you like,
but first you must always measure waterflow. We do a flow-right test to determine what
sprinklers or pop-ups or different drippers we need to use for our garden, so we need
to measure the pressure of our water. The way we do this is we need to grab a simple
9-liter bucket and also a timer. For this one I’m using the timer on my phone. The equation
you would use to measure you maximum flow pressure in your garden is to simply measure
the amount of liters that your bucket or watering can is. So in this case it’d be 9 liters.
You need to then divide that by the amount of seconds it takes to fill the bucket. You
then need to times that by 60, which is the amount of seconds in a minute, and that will
work out your maximum flow rate per minute. Now that you’ve drawn up your garden, you’ve
measured, and you’ve also done your waterflow test, you’re now ready to start installing
your irrigation system.
