How to make a rotating irrigation system using plastic bottles – 10 cents is enough
1. Gather Materials
Two large plastic bottles (1.5 to 2 liters each)
Bamboo skewer or metal rod
Thin tubing or straws
String or thin wire
Scissors or craft knife
Awl or nail
Hot glue or waterproof adhesive
2. Prepare Bottles
Clean both bottles.
Cut the top off one bottle (water reservoir).
Cut the bottom off the second bottle, then cut it in half lengthwise (water wheels).
3. Create Water Wheels
Glue straws or tubing inside the curved pieces.
Ensure connections are sealed and secure.
4. Assemble the Rotating System
Insert skewer or rod through the center of the water reservoir.
Attach water wheels to the skewer/rod, balancing them. Secure with string or wire.
5. Make Water Inlet Holes
Punch small holes near the bottom of the water reservoir with an awl or nail.
6. Set Up the System
Position the system in your garden.
Elevate the water reservoir slightly.
7. Add Water
Fill the reservoir. Water will flow through the holes, rotate the wheels, and spray water.
8. Maintenance Tips
Ensure water wheels are balanced.
Adjust hole size and number to control water flow.
Regularly check for and clear clogs in straws/tubing.
By following these steps, you can create an effective and low-cost rotating irrigation system using plastic bottles.
