Irrigation Upgrade Week 4

All Green, Tee and Fairway sprinklers and lines have now been installed. TE contractors did their final touch ups Monday and are no longer on site.

                                                   Packed up and ready to roll out
We still have some surrounds and scour valve lines to install when we have access the trenching machine as Jetline required it for their own work. 
                                                 One of the final "cuts" in the last trench

Work will now commence on cleaning up excess spoil, consolidating /compacting trench lines for final grades and we will commence testing tee and fairway sprinklers. 
Wire circuits / comms and V.I.H greens sprinklers have all been tested successfully.  

We had a little set back with a 200mm tee leak from the stage 1 works not related to the stage 2, this area has been isolated and will be fixed this week. 

During the next week we are also attending front 9 V.I.H maintenance before the irrigation season, some disruption with water going off as we test may be experienced and I apologise for any inconvenience while we attend this important pre season test and maintenance. 

Finally another shout out to say a huge thank you to all the volunteers who have turned up over the install period, back filling and clearing trenches. Thanks to Jetline for the supply of the trencher and Mick Lines for his operation expertise !!!  

Happy Hooking

Sprinkler Questions

I have received some questions regarding the differences in the outer appearance of sprinklers from the stage 1 Front 9 sprinklers installed 8 years ago to the back 9 sprinklers being installed as part of the stage 2 install. Namely the difference in size of the exposed "top"

The Toro Flex 800 B sprinklers being installed on Tees and Fairways have exactly the same internal components and specifications as the front 9 ones, the only difference is in the casing which has a lower rated pressure capacity (still within our requirements) with a smaller footprint. 

 Two main reasons I decided on these sprinklers, firstly it was more cost effective, saving a considerable amount of funds, bringing down the overall cost of the system along with other measures in order for it to be affordable and actually go ahead and  also allowed for extra funds to improve the green V.I;H sprinklers.

               Flex B series being installed on back 9                   DT series on front 9

The second reason was for maintenance, The front 9 sprinklers have a small diameter control tube, (above picture on right) when staff are trimming sprinklers as part of maintenance, they have to be careful not to snick the tube causing the sprinkler to not operate properly. This adds extra time to the task and when the tube is accidentally snicked it requires us to partially dig out the sprinkler, cut  the tube and reattach, if not enough tubing remains we need to totally dig the sprinkler up and fit a new tube.
The Flex B sprinklers ( above picture on left) do not have this tube avoiding the above issues.

The other major change to sprinklers are the Greens Valve in heads. (Individually controlled sprinklers).
I decided to upgrade to Infinity sprinklers from the DT series as installed on the front 9, (Infinity series sprinklers were not available at the time the front 9 was installed and are simply an advancement) for maintenance reasons. 

 With the iron in our water part of our sprinkler maintenance requirements are to clean / replace pilot valves that control the operation of the sprinkler, other issues sometimes experienced are decoder problems and coils, all of which are buried and require us to dig the sprinkler out, being careful of wiring, perform the necessary maintenance and then re install and set to level the sprinkler, a time consuming and expensive maintenance procedure.
                             Front 9 V.I.H Greens sprinkler with typical associated buried wiring

The infinity series sprinklers overcome this issue by having all the serviceable components within the sprinkler (explains the larger diameter exposed "top"). When we need to perform maintenance or repair we can access the components by removing the top of the sprinkler with no need to dig the sprinkler or components out of the ground. Making maintenance more user friendly and less disruptive for players.

As of Today we only have a few sprinklers to install, the piping to all tees and fairways is complete however we are waiting for some parts before we can finish the install on 18. Hopefully by Tomorrow afternoon. This will the leave the 10th ,11th surrounds and lawn area to complete once we have the Trencher back.  
Total Eden completed their work and have left site. We will be testing and commissioning the system next week.

Irrigation Upgrade Week 3

The contractors finished installing the man line, The greens V.I.H and wired them into the wire loop they will be installing lightning protection rods this week along with some final clean up and their work will be complete. 
                                                              See how its done !

The wiring will be brought online with the updated new works and specifications uploaded into our Central Computer System By Toro Techs. We may need to run a separate cable run to the back 9 bore pump before we can bring that on line which is being reviewed.

I wished I could say our component went as well, but with 2 trencher breakdowns we lost 3 days trenching and associated pipe install work.
                                               This "aint" digging nothing!!

We hired a small trencher and worked well into the night Wednesday to at least get some smaller areas trenched and ready for piping in an effort to keep moving forward. Staff also prepared and pre glued many of the fittings which saved a great deal of time once we could start piping up again.

                                                            Trenching in the moonlight (A new top 20 hit)

By Thursday the trencher was up and running and with staff (Ben Dean and I as Sarah is at TAFE) and many volunteers rallying over the two days we made significant progress, not completely catching up on loss time but through everyone's efforts making significant inroads, completing the 10th and 12th holes and trenching 16 and 17.

                                      The Chain gang                            One big Tree stump

                   If we leave we can make it a bunker !!        Looking back how far they come

 16 was piped up Saturday morning with Sprinklers installed and is now ready for backfill Monday.

                                     All the hard work Sprinklers installed on 10 working fine

Monday we hope to have the 17th complete and trenches dug on 18 with some piping done. Fingers crossed the trencher holds together and the weather is fine as we have drafted in a few more volunteers to work on the chain gang ( backfilling and clearing trenches) and have lined up Alan Sanderson who has been helping glue up and for Monday we have Ron Grant as well taking the place of Tony Holst who helped on a spare day last week

Till next time
