Irrigation woes

This sunny dry weather certainly put everyone in better spirits, so much better than week after week of watch rain fall and see the course waterlogged. However it has highlighted one problem we have been battling with over the last few weeks, we have been having issues with the wiring on the irrigation system, the system itself is nearing 40 years old and the wiring along with the pipe work are showing signs of deterioration. The pipework we have known for a while to have issues with the glue joints breaking under pressure. However this spring when the system was opened up we had a number of faults appear on the computer which controls the decoders to turn the sprinklers on and off. These error codes showed us that the signal was not getting through to a number of greens. After a lot of testing we initially though we isolated the problem to 2 areas, where the wire ran between boxes behind the 7th green and the 4th green and between boxes 15th green and 15th tee.

The irrigation contractors then mole ploughed a wire in to replace these 2 sections.m Once complete the system was tested again only to find the signal was getting to more greens but not them all. Testing each decoder after that we established that corrosion, earthing and fatigued cable was weakening the signal passing through the existing cabling, normally a constant voltage of 30v is needed we found a fluctuating current of between 1 and 20 volts. This was why we were not getting power to the furthest of the greens. We have since mole ploughed another section of cable in to get power to all but 3 greens. We are now at a point where we are deciding the best way forward in making the system useable.

Unfortunately when ploughing in a cable the contractors hit the tank fill pipe which left us withouitn water for a couyple of days a flooded the 15th faiway.

Given the dry weather the greens have suffered as a result. A lot of hand watering has had to be done to keep some greens alive.

Now we have water to most greens we have started to verticut to remove quite a build up of lateral growth. We have also microtined with star tines to minimise surface disruption and lightly topdressed with straight sand. This will be repeated next week, when we hope to get a fertiliser on the greens to promote recovery from the winter wear.

The area levelled at the end of the range has now been seed and raked. This should grow in once we get some rain.
