The pipes with the holes in them are for collecting the water and bringing it to the drain pipe which will run the water out to the street. The perf. pipe rest on the landscape fabric, {the long green rolls}.  The drain rock,[BACKGROUND]  will be between the perf. pipe, which run 4 feet apart, and 2 inches on top. 

3 inch perf pipe does not come with a sock so we made our own.
