Case Studies
Real results from real installations. Every case study includes independently verified data.
The full Case Studies library is being compiled and will grow here over the coming weeks. The founding documents below are available now. For a specific paper or trial report, contact us and we'll send it directly.
The Western Australian Golf Club
Committed to 8" and 10" inline units on PW's documented track record — before the handheld trial. The ¾" handheld trial produced results described as “remarkable.”
Verified: Idris Evans, Superintendent
Marri Park Golf Course
Metered year-over-year: 30.1% less irrigation demand for the entire season when compared to the average of the previous 3 years.
Verified: Marri Park Golf Course — metered

Verified: Ben Archibald, Founder, Touchwood Nursery
SR TAFE University · Organic Tomato Trial
Three-bed controlled trial, Bunbury WA. Vortex-only bed +23.25% yield and Brix 0.5→3.0; vortex+scalar bed +141% yield — all on 18% less water.
Verified: SR TAFE University — published methodology
City of Armadale — Gwynne Park
4.7 ha sporting precinct on 1974-era infrastructure. 13,839 kL saved, 60% less fertiliser, 9.9-month payback, 121% Year 1 ROI.
