Explanation:

Subsurface irrigation is a highly-efficient watering technique that reduces outdoor water use by 30 to 40 percent. The system consists of drip irrigation tubing planted about five inches below the surface. The water goes straight to your lawn's roots, and it doesn't blow away or run down the sidewalk.
How to Use Subsurface Irrigation
A subsurface irrigation system is best for new yards. Make sure you remove your hard, impacted soil surface and replace it with a good quality soil. Otherwise, you may get bare spots in your lawn.
The subsurface irrigation tubing is laid out in a grid pattern about 12 inches apart. Each emitter applies water at a constant rate of 0.6 gallons per hour. The emitters also have features that flush out small pieces of dirt, rock and debris that can get inside the tubing.
