#12 Green Drainage

 Green #12, no problem in the drainage was suspected. This green has done rather well in the past, however we have to check it out to be sure.
 We had started tracking the dran line back from the drain basin all was going well until we got close to the green and the hose came to a stop. Not Good.

This picture shows two different sites that were dug up. The one in the background is where the wye (tee) leading to the bunker on the right side of the green is tied into the green drainage.
 The hole on the bottom of the picture is where the problem began.

The drain line took a huge dip in elevation (in the wrong direction of course). The bottom of the picture is the same side of the green, the drain pipe was well below the 2" irrigation pipe that is showing. When you look at the pipe on the top side of the picture, the pipe is six to eight inches higher. Water does not drain upwards on a 90 degree angle.

 A 2nd picture of the drain piping. Look at the difference in the elevation of the pipe on each side of the 2" white PVC pipe.
 If you'll look at the white pipe on the right side you can see where the 4" drain line makes darn near a 90 degree turn. Remember the green is on the left side, the pipe is lower on the left side, really!!!
 All repairs have been made and we are moving on to #16,17,18.
