Drip Emitter Areas (Areas for Drip Emitters) Showing Incorrect Emitter and/or Flow Quantities
Issue
One or more drip emitter areas (Areas for Drip Emitters) in your drawing are showing incorrect emitter and flow quantity.
You've already sized your laterals and/or have run an Irrigation Schedule and have found that the flows or emitter quantities per container type do not reflect the manual calculation you've completed as a cross-check for the affected planted area.
Cause
This issue may be occurring because your drip emitter area is not including the correct bounding poly points from the planting area hatches in your planting Xref.
Solution
To resolve the issue, make sure your drip emitter area is fully encompassing the hatched planting areas it's supposed to irrigate – or at least ensure that at least 50% of the planting area's bounding polyline points are included in the drip area. If the drip area accounts for less than 50% of the plant hatch bounding points, its emitters will not pick up that planting area.
In this example, the planting area shown to the right is covered by a drip emitter area, but when the system is sized, the flow rates appear to be incorrect.
In this case, let's say we run an Irrigation Schedule and it lists the emitter quantity based on how we set up the emitter count to container size, and that quantity is off.
In our example, the schedule is showing 55 emitters when it should be showing 44 (1 emitter per plant).
Back in the drawing, the emitter area appears to be covering the majority of the groundcover hatch, but when we actually select the planter area, we can see how many points are not in the emitter area.
If we examine the area, we can see that the planting hatch includes 11 points.
After zooming in closer, we can see that 6 of those 11 points are within the drip emitter area, which is the exact quantity the emitter area is picking up in the schedule.
In this case, we would need to expand the drip emitter area to encompass the additional 5 points included in the planting area boundary.
