Desert Control Expands Strategic Golf Course Pilot for Water Conservation with PGA WEST

La Quinta, California, 27 March 2025 — Desert Control (DSRT) is advancing to the next phase of its structured golf course pilot program with PGA WEST, one of the largest and most prestigious golf destinations in the United States. The expansion follows a successful small-plot pilot on the Nicklaus Private Course, where Desert Control's solution delivered measurable improvements in water efficiency, energy savings, soil quality, and turf health.

The new project will expand deployment from a single tee box to approximately four acres, including tee boxes, fairway, rough, and mounds fronting residential zones. This marks a significant progression to Stage 2 of Desert Control's three-stage deployment model, which is designed to support high-value clients in moving from technical validation to full-scale commercial rollouts.

"This expansion reflects the tangible value our solution brings to clients managing large, water-intensive landscapes," said Managing Director of Desert Control Americas, Marty Weems. "PGA WEST's decision to scale up this program is a strong signal of confidence and aligns directly with our strategy to convert pilot success into commercial deployment across entire golf properties. Our team is energized by the enthusiasm with which users are talking about what they observe from the impact of LNC."

The small-plot pilot, implemented during the summer of 2024, continues to demonstrate water savings greater than 25% and noticeable reductions in energy use for pumps and irrigation systems. Treated turf also showed faster germination and recovery, stronger resilience under stress, and improved visual performance — while maintaining world-class playability. In addition, soil salinity decreased, soil health improved, and operational strain on irrigation infrastructure was reduced. These validated results have prompted PGA WEST to now move forward with implementing this four acre treatment project in the second quarter of 2025, and to further conclude on full-course deployment decisions before the end of the year.

PGA WEST spans over 2,000 acres in La Quinta, California, and includes nine championship golf courses designed by legends such as Jack Nicklaus, Arnold Palmer, Pete Dye, Greg Norman, and Tom Weiskopf. It is home to thousands of residences and serves as a host venue for The American Express PGA TOUR event.

Owned in partnership with HKI America, Inc and managed by co-owners, Century Golf Partners (CGP), PGA WEST represents a strategic reference for Desert Control's growth in the U.S. golf sector. The long-term potential includes treatment of all irrigated turf and landscaped areas, creating one of the most comprehensive water efficiency transformation projects in the golf industry. The nine PGA WEST properties are part of a portfolio of sixteen owned by HKI and more than forty-five courses owned and/or operated by CGP. The Citrus Club in La Quinta CA and Walt Disney World Golf in Orlando, FL are also part of the CGP portfolio.
