Commercial irrigation design by a certified irrigation designer.
Most water waste is designed in. Spray heads throwing onto asphalt. One zone serving four microclimates. Pressure so high the heads mist instead of watering.
These aren't maintenance problems. They're design problems — and no amount of scheduling fixes them.
Half your water is lost before it reaches a plant.
EPA's guidance for commercial and institutional facilities states that improving an irrigation system's efficiency could save a property more than half of its outdoor water use — water lost to wind, evaporation and runoff caused by poor design, installation and maintenance.
The mechanism is uniformity. When a system waters unevenly, you're forced to over-water an entire zone to keep its driest corner alive — which is how a property ends up using far more water than it needs and still having brown patches.
Uniformity is set by design: head spacing, matched precipitation rates, correct pressure. No controller fixes it afterwards.
Pressure, flow, pipe sizing
Calculated for the site — not estimated from a walk-around. Over-pressure is why heads mist instead of watering.
Head-to-head spacing
Matched precipitation rates and correct spacing, so water lands evenly and you're not over-watering to compensate.
Built to be measured
Flow sensing specified from the start — so the system reports its water use from the day it's commissioned, rather than being a black box.
Commercial irrigation design — the questions worth asking.
What does a commercial irrigation design include?
A proper design includes site and hydraulic assessment, water source and pressure analysis, zoning based on microclimate and plant type, pipe sizing, head selection and spacing, backflow prevention to municipal code, controller and flow-sensor specification, and as-built documentation. The design determines the ceiling on how efficient a system can ever be — no controller and no maintenance regime can outperform a bad layout.
Why does uniformity matter?
Uniformity describes how evenly a system applies water across a zone. When it's poor, you're forced to over-water the entire zone to keep its driest corner alive — which is how a property ends up using far more water than it needs and still having brown patches. EPA's commercial guidance notes that improving irrigation efficiency could save a property more than half its outdoor water use. Uniformity is set by head spacing, matched precipitation rates and correct pressure — all design decisions. No controller fixes it afterwards.
Do I need a certified irrigation designer?
For a commercial property, it matters more than most people realize. Certification covers hydraulics, zoning and system layout — the elements that determine whether a system wastes water for its entire service life. Much commercial irrigation is laid out by whoever won the landscape tender, which is why so much commercial water waste is designed in rather than caused by neglect.
Can you redesign an existing system?
Yes. Most commercial sites don't need replacing — they need specific zones redesigned. Spray heads throwing onto asphalt, one zone serving four microclimates, or pressure so high that heads mist rather than water are targeted problems with targeted fixes. We assess what's there, identify which zones are actually costing you money, and show you the payback before you commit.
Do you design green roof and amenity terrace irrigation?
Yes. Rooftop irrigation is a different engineering problem — pressure regulation across elevation, wind-resistant distribution, structural weight limits, and integration with the roof's water-retention and drainage assembly. It also sits above a waterproofing membrane and occupied space, so a failure becomes a building leak rather than a brown patch. In Toronto, the Green Roof Bylaw makes irrigation a mandatory provision on qualifying buildings.
Will the design work with monitoring?
Yes, and we specify for it deliberately. Flow sensing and controller capability are designed in from the start rather than retrofitted later, so the system reports its water use from the day it's commissioned. A system that can't be measured can't be managed.
