In 1995 the irrigation system at Silver Lakes Country Club in Helendale, California was completely renovated. The system included a 5000 gpm pump station, 16” to 4” mainlines, 2” laterals, 4,000 Rainbird 700 and 750 heads as well as 88 Rainbird MSC 24 station clocks. The heads were individually wired back to the clocks but were paired up, with 3 to 4 heads per station in fairways, roughs and perimeters causing inefficient water usage.
In 2000, IGM added 3 more legs of communication wire and 74 clocks. This nearly gave us individual head control. In 2008, we were having a very hard time getting the clocks repaired because parts were hard to get. The costs were so high that it did not make sense to have them repaired any longer.
At the end of 2008, we started the first phase of upgrading the clocks to a Rainbird PAR Plus with 72 station capacity. One of the nines was completed in February of 2009. The other two nines were started in December of 2010 and were finished at the end of February 2011.
The process included obtaining funding from the Association by preparing a thorough cost-benefit analysis. Subsequently, a presentation was made to the Board of Directors. Detailed maps and clock assignments were then made for re-wiring the new clocks. All of the flow zones and branches were redone in order to give us more control of the system. The old clocks were taken off of the concrete pads and the new clocks were installed. In most cases, all of the wiring had to be put back into one clock where there were two. We went from 88 flow zones and 24 branches to 500 flow zones and 34 branches. Then all of the data needed to be reprogrammed in the computer. The irrigation maps are broken down into separate holes, finalized, laminated and put into binders for the GCS, AGCS and irrigators.
