Drainage issues.

Long standing members may remember the drainage work which was carried out on the 5th, 8th, 11th & 16th greens back in 2001.
The work was carried out by a contractor using a system called "Turfdry". The system involved inserting "ribbon" drains into multiple narrow channels at a depth of 400mm. The "ribbon" drains measure 150mm x 25mm. The photos below show the material and the drains exposed in a trench.

The problem with the system is the drainage channels are so narrow they quickly become contaminated with fine particles and the water never manages to reach the "ribbon" drains. 
When we exposed these drains this week, out of a total of 20 lines only 3 had water in them.
