BUNKER IMPROVEMENT WORK

BUNKER IMPROVEMENT WORK
With the recent change in weather patterns, bringing in torrential rain, you will find the
bunkers, particularly those at Palm course, collecting water. Some bunkers with old
drainage lines, which have over the years lost their efficiency due to the collapsed pipes or
roots invasion, have water ponding after every downpour and are unplayable.
The golf course maintenance team is progressively carrying out bunker improvement works
by checking the drainage lines and replacing failed pipes. We have discovered that the old
pipes have slit lines on the undersides resulting in underground roots invading them and
causing the pipes to block the flow of water.
We have removed the blocked lines, replacing them with new solid pipes while ensuring
good gradient flow. We have also backfilled them with USGA spec bunker sand and
compacted the surface to playable conditions.
Under the bunker sand where water needs to be drained out fast and where there is no
threat from tree roots, the team used flat pipe (mega flow) wrap with geotextile for fast
drainage.
The improvement work has been put to test after downpours and we are happy to report
that those with the new drainage lines installed are no longer collecting water.
Work has been carried out at Palm course hole 8 (2 greenside bunkers) and hole 10 (3
greenside bunkers). Lake course Hole 1 (1 greenside bunker), hole 3 (2 fairway bunkers),
hole 6 (2 greenside bunkers) and hole 9 (2 greenside bunkers).
