Over the past 10 years, thatch has built up on our fairways. Since it is not economically feasible for us to regularly aerify and topdress our fairways, the thatch has made our drainage basins to appear sunken or collapsed. We have started raising drainage basins on some of our fairways that were needed the most. I am mainly focusing my attention on fairways #1, #4, #9 and #14. We have started on fairway #9 and below are the steps that we took:
1) Obviously we cut out the sod around the drain
2) Dig the gravel and dirt out around the drain
3) Add a 12 inch coupling to the pipe
4) Cut a new 12 inch pipe so that is flush with the fairway
5) Drill two holes into the top of the pipe so that we can screw the metal drain onto the pipe
6) Add gravel and sand so that the drain will facilitate quicker drainage
7) Add the sod to the sand layer and pack it down
