Watering crops by hand in Once Human gets old fast. The Automatic Irrigation Facility fixes that by spraying water over everything in a circle around it. To get the recipe without the memetic route, you first have to find a physical Irrigation Facility out in the world, break it down, and bring it back to your base for Reverse Engineering.
Quick answer: Go to East Blackfell Junction in Iron River. Climb to the roof of the central hospital, recycle the yellow tripod device with [R], then research the Automatic Irrigation Facility at a Tech Research Workbench.

You’ll know the pickup worked when an “Irrigation Facility +1” notification appears on screen. From there, you can head back down through the hospital and return to your base.
Unlock the Automatic Irrigation Facility recipe
Carrying the device around doesn’t unlock anything on its own. You have to turn it into a recipe at your Tech Research Workbench.

A “Recipe Unlocked” message confirms it worked. After that, the Irrigation Facility becomes available to place in Build Mode.
The Irrigation Facility can also be unlocked through memetics, so you may already have it if you’ve invested in the farming and water nodes.
What the Irrigation Facility needs to run
A placed sprinkler does nothing until it has both power and water. Make sure your setup covers each of these:
- A power source supplying at least 2 Watts, such as a generator or solar panels.
- A water hose connected from a source of Dirty Water, Purified Water, or Boiled Water.
- Planter Boxes inside its circular watering area, which appears while you place it.
If you turn off the area preview, keep Planter Boxes within three boxes of the facility horizontally or vertically and within two boxes diagonally. Hovering over the unit also shows a Target Irrigation setting. Set it to a level that works for every plant in range, since different crops need different amounts of water.
