The installation process is a time consuming and labor intensive endeavor. I have included a simplified version of the process through the following photographs.
First, the entire putting surface must be meticulously mapped with a laser level to account for all undulations and contours. Once this process is complete, the overall drainage template is designed for the green.
Once the drainage pattern is established, the actual trenches for the drain lines are cut. Prior to trenching, the sod is carefully removed and cataloged so that each individual sod piece will be placed in exactly the same location following the back filling of the trenches. This will allow the sod lines to blend into the rest of the green, rendering them unrecognizable upon completion of the project.
The last step of the process involves replaces and tamping the sod. The photograph above was taken one day after the installation was complete. In only a couple 0f weeks the seams will be barely noticeable. Stay tuned, as next week I will detail why the drainage project is an essential part of our overall greens maintenance program at NSCC.
