Your piping, HDPE and specter of friction loss
We’ve just finished an irrigation renovation at Anthem Country Club in Las Vegas. The lowest point on this Hale Irwin/Keith Foster routing sits at 2,600 feet above sea level. The high points, the 15th and 16th holes, climb to nearly 3,000 feet. That right there was the issue - the water pressure on those holes was never great. After 23 years, the club’s patchwork irrigation system was flat out failing. The turf conditions on those high holes were the proof.
The Anthem CC job has been one for the ages. Nine holes are finished and there are still nine more to go, but everything that could have out there happened did happen. It took nearly four years (and two club management teams) to gather the institutional will to even undertake the job - and foot the bill. Working in the desert is really tough, mostly on account of something called caliche, a naturally occurring calcium carbonate that binds to other materials like concrete. Trenching and laying pipe in this stuff is a nightmare. And perhaps most traumatic of all, our irrigation designer, Bob Bryant - a legend in the golf business for his knowledge and ingenuity - passed away two months into construction.
But god bless him, Bob’s design at Anthem was indeed the stuff of legend. Superintendent James Symons chose to go with The IC System from Rain Bird. Heritage Links, my company, installed it. About three months after Bob passed away, the pandemic hit - but that didn’t stop the nine “high zone” holes at Anthem CC from reopening in May 2020. The low zone holes could be undertaken as soon as 2021.
