Simple PVC irrigation systems are a great low cost way to water your garden. I’m always on the lookout for different PVC irrigation designs, and when we went to a friend’s house for dinner recently, he showed me his very simple PVC system. He has small, 8 foot raised beds that he buries a 2” PVC pipe about 6” under the soil. The pipe has holes spaced laterally on both sides of the pipe to allow the water to seep into the soil.
Before burying the pipe, he puts a cap on one end and a 90 degree elbow on the other end. In the elbow, he inserts a 3 to 4 foot extension that he then fills with water. The water will slowly leak into the soil at the root zone of the plants—very ingenious. There you have it, a very simple, but effective PVC system for small raise beds.
I’d love to hear about any PVC systems you’ve designed or used. How did they work?
