THE UTAH AUTHORITY

Utah's research authority on landscape water reduction.

The Plant Institute Inc. is a 501(c)(3) nonprofit running continuous measurement and reduction programs across Utah's three primary climate zones — Wasatch Front, Southern Utah, and the Uintah Basin. Our field data is the foundation for how we advise cities, districts, and property owners.

THE STATE OF UTAH WATER

Utah is the second-driest state in the country — and a leading per-capita residential water user.

For decades, Utah residents have watered landscapes that were never designed for a high-desert climate. The result: per-capita residential water use that places Utah among the highest in the arid West, despite comparable climates and shrinking reservoirs.

The Great Salt Lake has lost more than 70% of its surface area since 1850. The Colorado River system, which supplies a significant share of the Wasatch Front's water, is operating at historic lows. Every major Utah utility has implemented tiered rate structures. Conservation is no longer optional — it's priced in.

The Plant Institute Inc. was founded to address this at the landscape level, where the majority of Utah residential water actually goes. We reject the idea that reduction requires ugliness. Our approach is built on peer-reviewed canopy and turf research, and our program is designed around a 30–60% reduction target — verified at your water meter 12 months after implementation.

OUR TWO SYSTEMS

JLB Canopy Management + GreenRx Plant Optimization.

Both systems are designed as research protocols — not service SKUs. Methodology and measurement are published with every project.

JLB Canopy Management System™

A structured approach to pruning, layering, and shade architecture

Built on a decade of canopy-ET research, the JLB method prescribes specific cut types and canopy layer sequences that reduce evapotranspiration demand on the landscape beneath. On mature Utah canopy (maple, ash, locust, sycamore), structural corrections often produce the largest single reduction lever on the property.

GreenRx™ Plant Optimization Protocol

Diagnose soil. Tune irrigation. Recalibrate the controller.

GreenRx begins with physical soil cores — infiltration, compaction, root-zone biology — and ends with an irrigation and controller prescription. Corrections are concentrated on the zones where the climate fundamentally mismatches the planted landscape.

CLIMATE ZONE REFERENCE

Three Utah climate zones. Three reduction strategies.

The same protocol doesn't work everywhere. Our prescriptions change by zone, and the reduction profile with it.

Zone 1 — Wasatch Front

Ogden · Salt Lake City · Provo corridor · 14–18 in annual precipitation · winter-dominant

Strategy: Aggressive JLB canopy layering on existing deciduous trees; GreenRx prescriptions on lawn and shrub beds.

Typical design target: 40–55% reduction.

Zone 2 — Southern Utah

St. George · Cedar City · Washington · 8–10 in annual precipitation · monsoon influence

Strategy: GreenRx-led, with JLB secondary. We retain functional shade canopy and optimize water-hungry turf.

Typical design target: 50–60% reduction.

Zone 3 — Uintah & Eastern Basin

Vernal · Roosevelt · Duchesne · 8–12 in precipitation · extreme temperature swing

Strategy: Windbreak-first canopy design, soil moisture retention, and controller programming calibrated for extreme diurnal swings.

Typical design target: 35–48% reduction.

Statewide FAQ.

Is outdoor water really the majority of Utah residential use?
In most Wasatch Front utilities, outdoor use ranges from roughly half to over two-thirds of annual residential consumption, with mid-summer peaks above 70%. Source: Utah Division of Water Resources municipal reports.
Can landscapes really be reduced 30–60% without looking worse?
Yes — that is the design premise of our program. Canopy engineering actually improves tree health and reduces heat stress. We publish a verification report from real meter data 12 months after implementation on every project.
Does Utah rebate water-conservation landscaping?
Most major utilities offer smart-controller, flip-your-strip, or turf-conversion rebates. The Plant Institute files rebate paperwork on your behalf at no additional cost, and we track current rebate levels across all 11 utility jurisdictions we serve.
How does The Plant Institute relate to public campaigns like Slow the Flow?
Slow the Flow is a public-awareness campaign. The Plant Institute is a measurement and implementation program. We're complementary — we cite Slow the Flow's data in our statewide analysis.
What's the Great Salt Lake connection?
A substantial share of the Great Salt Lake's declining inflow is attributable to upstream consumptive use. Landscape irrigation is the single largest consumptive category on the Wasatch Front. Reducing it is the shortest path between individual Utah households and the Lake.
