What the trial measured
What the site reports
THE STANDOUT RESULT- Touchwood Nursery reports a saving of 15,000,000 liters over the 12 months to 26 May 2025.
- That is 16.85% of the nursery's 89,000,000 liter annual water license.
- The nursery states it typically uses its full license allocation or slightly exceeds it.
- A single 100mm President Water vortex generator was installed on the irrigation supply in January 2024; the reported 12-month window runs to May 2025.
- The founder states the reduction was achieved while continuing to deliver healthy plants, with no drop in output quality reported.
The operation
- 15-acre wholesale nursery on the southern outskirts of Perth, Western Australia.
- Over 20 staff, supplying the retail and landscape trade.
- One 100mm unit treats the irrigation supply for the whole site.
- The nursery frames the saving as part of a broader commitment to sustainable water management rather than as a trial outcome.
Basis of the figures
- The figures come from a signed letter from the nursery's founder, dated 26 May 2025.
- They are the site's own numbers. No third-party audit, billing extract or meter record was supplied alongside them.
- The saving is expressed against the license allocation rather than against a measured prior-year consumption figure.
- President Water's own internal summary of this letter recommends the figures be attributed explicitly to the customer rather than presented as verified test results. This page follows that recommendation.
“Our license is for 89,000,000 liters per year, which we use or go over slightly. Over the past 12 months, this innovative system has saved us an extraordinary 15,000,000 liters (16.85%) of water.”
A wholesale nursery lives and dies on its water license. Touchwood runs 15 acres of container stock in a Mediterranean climate on an 89 million liter allocation it already uses in full, which means every liter saved is either headroom it did not have or stock it could not otherwise carry.
The reported figure is 15 million liters over twelve months from a single 100mm unit on the main supply. If that holds, it is close to a sixth of the license recovered without changing anything about how the nursery is run.
The honest framing matters more here than the number. This is a customer letter, not a trial. There is no untreated block at Touchwood running alongside the treated one, no metering method on record, and no plant measurements to sit beside the water figure. Rainfall, planting mix and any other efficiency work done since January 2024 are not accounted for.
So read this as what it is: an operator with a license to protect, over a year into running the equipment, putting his name to a number. That is worth something, and it is a different kind of evidence from the Marri Park meters or the SR TAFE beds. It should not be added to them or averaged with them.
