Smarter water. Better courses.

Precision irrigation.
Exceptional outcomes.

Vorterra delivers smart water solutions designed for the unique demands of golf courses — improving playability, reducing water use, and lowering the line item every superintendent answers for.

Less waterReduce water use without sacrificing course quality.

Healthier turfDeeper infiltration and a wetter root zone from the same heads.

Lower costsPassive inline hardware that pays for itself out of the water bill.

Open soonerFaster overseed establishment — earn green fees weeks earlier.

Run your course's numbers How it works

The opportunity

Water is the line item
that never stops rising.

Ask any superintendent what keeps the budget meeting long: it's the water — the cost of it, the restrictions on it, and the expectation that the course looks flawless anyway. That bill is exactly where Vorterra works.

The big one · playability

The overseed closure isn't a cost.
It's revenue on a timer.

Every fall the course closes five, six weeks — scalp the summer grass, seed the winter rye, wait for it to come in. The day it's deemed playable is the superintendent's call, and every day before it is revenue that never existed. Faster germination and faster establishment move that call earlier. Reopen two weeks sooner and you didn't cut a cost — you found revenue.

≈ 4.1× a year of the Vorterra lease at this page's calculator settings — the reopening alone can pay for Vorterra for the year. The water savings after that are gravy.

The two-week figure is the pilot's target, not a promise — it's exactly what a nine-vs-nine overseed trial measures on your course, with your rye, your call. Supporting signal: Vorterra ground consistently reports faster early growth — nearly 2× sapling development at two commercial tree-fruit and avocado operations, and stronger stand establishment in the University of Arizona evaluation.

The technology

One spool on the pump station.
Nothing else changes.

A Vorterra unit is a flanged inline spool that installs downstream of your pump station in under an hour — no electricity, no chemicals, no moving parts, invisible from the cart path. Inside, a fixed geometry spins water into a vortex and collapses it, lowering surface tension so water wets in instead of sheeting off.

On turf, that reads as faster infiltration on greens and approaches, fewer hydrophobic dry spots to hand-water, less runoff on shaped slopes and bunker faces — and room to shave run times without the course telling on you.

Vorterra unit installed inline on an irrigation supply line — **The actual hardware.** A Vorterra unit inline at the University of Arizona trial — every drop through the unit.

Between the two flanges

What actually happens
to the water.

No moving parts · the water moves, the unit doesn't

Section along the flow axis. Fixed internal geometry spins the flow into a tight vortex; static pressure falls at the core until vapour cavities form, then collapse as pressure recovers — ordinary fluid dynamics in an unusual geometry. The water leaves the far flange with lower surface tension, which is why it wets into a green instead of beading on it.

Axial inlet

Water arrives the way your pump station delivers it — straight, pressurized, unremarkable.

Fixed helical geometry

Internal flow tubes turn straight flow into a fast, converging spiral. Nothing spins but the water.

Core pressure minimum

Rotation pulls pressure down along the axis until microscopic vapour cavities form in the throat.

Collapse & recovery

Past the throat the cavities collapse — brief, intense, repeated on every gallon your heads will throw that night.

Primary deployment · whole course

One unit at the mainline.
Every zone downstream is treated.

Pump station → whole system

The standard install: a 4″–12″ unit downstream of the pump station, sized to station flow. Every green, approach, fairway and rough head runs on treated water from the first cycle — one spool, whole-course effect.

Spot treatment · trouble areas

Or drop a 2″ unit on
the green that fights you.

Zone feed → one trouble area

A hydrophobic green, a slope that sheets, an approach you hand-water all summer — a compact 2″ unit installs on the line feeding just that area. The lowest-commitment way to watch it work on your worst spot first.

Install

Gaskets and bolts, not a project

Flanged both ends, 4″–12″ sizes to 4,400 GPM. Fits an existing straight run at the pump station. Leased, with a 10-year warranty — Vorterra retains service.

Dial back

The savings come from your fingers

The unit changes what each gallon does in the profile; the savings are booked when you shorten run times. Your central control makes it measurable night one.

Verify

Meter it like a trial

Run treated versus untreated — front nine against back nine, or one 2″ spot unit on your worst green — with your own flow data and moisture meters. Believe your numbers, not our brochure.

Straight talk

It's not a filter, a wetting agent, or a substitute for good scheduling. It doses nothing and adds no pressure. It changes how applied water behaves in the root zone — the reduction itself is a decision you make at the controller, which is exactly why it's provable.

Measured, not promised

The physics watering your fairways
just aced a university trial.

In a 97-day controlled evaluation at the University of Arizona's Yuma Agricultural Center — subsurface drip, sensor-scheduled, every drop through the unit — Vorterra moved every number that matters to anyone who manages irrigated ground.

Water productivity

+23.1%

More growth per acre-inch of applied water — the exact economics of a water bill.

Skipped irrigation

1 of 7

Of the season's 7 scheduled irrigations, treated ground skipped one — confirmed by soil-moisture sensors — and still out-yielded the controls.

Less input, same result

−27% N

Performance held with nitrogen cut by a quarter — fewer inputs moving through your turf and your ponds.

Results from a controlled agricultural evaluation (iceberg lettuce, May 2026); turf outcomes vary with soil, climate and management. That's why golf deployments start with a metered nine-vs-nine pilot on your own course. Multi-season commercial proof on reclaimed municipal water — the same supply many courses irrigate with.

The advisor

Nobody has read more greens
than Carl Jackson.

Fifty-four Masters. Fifty-two years at Augusta National. Thirty-nine of those tournaments on Ben Crenshaw's bag — including both green jackets. Carl Jackson has spent a lifetime reading how water moves through the most scrutinized turf in golf, and he sits on Vorterra's advisory board.

When the man who read Augusta's greens for five decades looks at your water, it's worth listening.

The documentary

Before it was a standard,
it was his story.

Carl Jackson left school at ten to help support a family of eleven, growing up in the Sandhills of Augusta, Georgia — separated from Augusta National's fairways by little more than a fence. He went on to caddie a record 54 Masters and win two green jackets on Ben Crenshaw's bag. The film takes its name from what he did with that distance, and the certification takes its name from the film.

The standard

Rise AboveCertification

A grade for how a course is kept.

Named for Carl Jackson's story, RISE ABOVE is a 100-point certification scored across the three things that actually determine a course's footprint: what you put down, what you draw, and what your soil holds. Independently verified, recertified every twelve months.

How it holds up. The standard is scored by a body independent of any technology vendor — no supplier grades its own customers. Soil, water, and PFAS results come from accredited laboratories on a fixed sampling grid. Points are awarded for measured outcomes, never for the equipment used to reach them: any technology that moves the number counts. Certification expires at twelve months.

Illustrative model, not a quote. Units sized at roughly one 4″ unit per 25 irrigated acres (final sizing is by station flow, not acreage); compact 2″ spot-treatment units for individual trouble areas are quoted separately. Savings are realized through reduced run times and verified against your own flow meters; results vary with soil, turf, climate and management. 1 acre-foot ≈ 325,851 gallons; household equivalent ≈ 300 gallons/day. Water-cost benchmarks: GCSAA survey data (avg. $107K/yr national, $238K/yr Southwest).

Prove it on nine holes

Front nine treated.
Back nine business as usual.

One unit at the pump station — or a single 2″ unit on your most stubborn green — one season, your own meters and moisture data. If the treated nine doesn't hold quality on less water, you'll know — and so will we. Units are leased with a 10-year warranty, so there's no capital request to write.
