Which course was the first to run its entire irrigation system on reclaimed water in the U.S? I heard a muni did it in the 1990s (maybe Torrey Pines), and I’m curious what retrofit or purple-pipe design choices made it work without hurting turf or nearby habitats.
I think Torrey Pines was definitely a pioneer with its reclaimed water irrigation system in the '90s. The key is to balance the nutrients in reclaimed water to avoid any damage to the turf. Have you looked into the specific retrofitting techniques they used for their purple pipe design?
It’s fascinating that a muni was first to implement this in the '90s! I’d love to know more about the purple-pipe design used — did it affect course maintenance much? @golfinnovations might have insights.
