There are many different configurations of in-line drip tube.
Micro-sprays should also be installed 'head to head'. This means that they need to be installed every 2m and your flow rate in litres per hour divided by 70 will give you the maximum number of sprinklers that can be installed on each zone. With some variation due to your flow rate and pressure micro-spays generally throw a 2m radius and need between 50-70L/hr for each sprinkler. Garden Irrigation System with Micro Sprays or Dripline:įor garden areas we recommend micro-spray sprinklers or dripline. This means that the area that is watered by the gear drives, will not receive enough water in the time it takes to water the area with the fan sprays, or the area with the fan sprays will be over-watered by the time it takes to water the area with the gear drives. Gear driven pop up sprinklers and fan popup sprinklers should not be used within one zone.įan sprays put down approximately 4 times the amount of water as gear drives in the same amount of time. So, when you are designing a system, wherever possible, break the areas up into rectangles and squares. Your lawn and garden areas will probably not be uniform rectangles or squares. If the area is wider than the radius of the sprinklers used then more sprinklers should be placed in the middle. So, it is better to position your sprinklers around the edge (see figure I.1). It is better to spray from the edge of lawn and garden areas into the middle. The first configuration means that there are no dry spots and that due to the overlapping of each sprinklers wetted area the run time for the zone can be reduced.Ģ.The second has dry spots and so the area needs to be watered for excessive durations to provide water to these dry spots. The drawings below which show a 10m x 5m lawn area with 6 sprinkler heads (figure I.1) and one with 2 sprinklers (figure I.2).ġ. Head to Head" coverage - sprinklers should be installed so that one sprinkler sprays onto the adjacent sprinkler. Lawn Irrigation System with Popup Sprinklers: Lets start the lesson off with popup sprinklers for your lawns. This means that you will get a very different precipitation rate across the zone, based on how long you water for, resulting in very uneven water coverage and inefficient water use. For your garden zones, avoid putting drippers / dripline and garden sprayers on the same zone.ĭrippers generally range from 1 to 24 litres per hour, whereas garden sprayers range from about 50 to 200 litres per hour. When designing, divide your gardens and lawns up into separate zones, where all areas within each zone will require about the same amount of water, at about the same frequency.ģ. Gardens and lawns require different amounts of water at different frequencies.
It is not a good idea to try to water your gardens and your lawns as one zone. In order to determine how many pop ups, garden sprinklers or dripline can be run per zone, it is important to know the flow rate at the desired operating pressure.Ģ. Roughly, most pop-up sprinklers require a pressure of at least 300kpa, garden sprinklers require at least 200kpa and dripline at least 100kpa. Things to remember when designing a system:ġ. All irrigation methods require different operating pressures to work efficiently. Click here to see our formula for performing a simple "bucket flow test". Alternatively you can hire our water flow and pressure tester for a hire fee of $100. Your flow rate - A flow test is important as it dictates how many sprinklers you can run at once.
