DIY Magic: Build a Rotating Irrigation System from Recycled Bottles


Looking for a clever and cost-effective way to water your plants? Look no further than your recycling bin! With a few plastic bottles and some household items, you can create a simple yet effective rotating irrigation system for your garden. This system delivers water directly to the roots, saving you time and water compared to traditional methods.

Materials Needed:

  • Two empty plastic bottles (similar size)
  • Sharp knife or box cutter
  • Nail or skewer (heated for easier puncturing)
  • Drill (optional, for larger holes)
  • Garden hose
  • Hose clamp
  • Optional: Spray paint (for decoration)
  • Optional: PVC pipe (for a taller sprinkler)

Step-by-Step Guide:

1. Prepare the Bottles: Wash and dry the plastic bottles thoroughly. Remove any labels or stickers.

2. Create the Sprinkler Holes: Using the nail or skewer (heated for a cleaner cut), poke several small holes around the sides of one bottle, focusing on the bottom two-thirds. These holes will allow water to spray out and sprinkle your plants. You can adjust the size and number of holes for a finer or heavier mist.

3. Connect the Bottles: Cut the bottom off the second bottle. This open end will be attached to the hose for water intake.

4. Join the Bottles: Here, you have two options:

5. Simple Method: Insert the neck of the bottle with sprinkler holes into the open end of the bottle without holes. Secure the connection with duct tape or strong waterproof tape.

6. Sturdy Method: For a more durable connection, drill a hole in the center of each bottle cap. Push a small piece of wire or a zip tie through both holes and twist to tighten, creating a secure joint between the bottles.

7. Attach the Hose: Make a small hole in the cap of the bottle without sprinkler holes (the one that will connect to the hose). Slide the hose onto the bottle neck and secure it tightly with a hose clamp.

8. Optional: Add Height (Using PVC Pipe): If you want a taller sprinkler for larger plants, drill a hole in the bottom of the bottle with the sprinkler holes. Slide this bottle onto a short piece of PVC pipe (ensure a snug fit). Secure the connection with duct tape or another strong waterproof tape.

9. Optional: Spruce it Up: Give your sprinkler a splash of personality! Use spray paint to decorate the bottles (avoiding the sprinkler holes).

Using Your Rotating Irrigation System:

  1. Place your DIY sprinkler in your garden bed, positioning it strategically to cover the desired area.
  2. Turn on the water hose. The water pressure will cause the bottle with sprinkler holes to rotate, distributing water evenly across your plants.
  3. Adjust the water pressure for a desired spray strength.
  4. When finished watering, turn off the hose and remove the sprinkler if needed.

Tips and Tricks:

  • Experiment with the number and size of sprinkler holes to find the optimal flow for your plants’ needs.
  • Consider using different sized bottles depending on the size of your garden bed.
  • Ensure the connection between the bottles is secure to avoid leaks.
  • This system is best suited for smaller plants or garden beds. For larger areas, consider additional sprinklers or a more elaborate irrigation system.
  • Empty the system after use to prevent mosquito breeding.

With a little creativity and these simple steps, you can have a functional and eco-friendly rotating irrigation system up and running in no time! Watch your plants flourish with this water-saving solution.
