Finished

I finished up the drainage project in between rains today. I finished the trench on the outflow pipe and connected the PVC to the corrugated plastic. The only other thing was filling in with the rocks. 

I didn't have a coupler so I wrapped a piece of tractor tire inner tube around it. After pulling it tight and putting in some crews it was pretty tight. It wouldn't hold pressure but it should be okay for rain water. 

The outflow needs a little dressing up. I might extend it further down the hill at some point.
