For every 100 square meters of green you need about 30 meters of drainage pipe, and we have to cover the entire surface in a 10cm layer of gravel.
We're cutting "V" trenches with an excavator, a method I picked up some 12-years ago. The "V" trenches are less prone to collapsing than the box trenches. I prefer "V" trenches just about everywhere. When it comes to installing irrigation lines, "V" trenches make is a hell of a lot easier to compact... something especially important if you've got clay-plastic type soils.

The drain lines have been marked with wooden stakes (usually they're painted in the ground, but this works equally well). The front of the green is at the bottom of the photo, the loader is just off the back. The green is 65 meters long; almost a full Lob Wedge.
