Irrigation Design & Engineering
Engineered for performance, designed for beauty.
Every Zenith irrigation design begins with rigorous site analysis and hydraulic modeling — producing systems that deliver precisely the right water, to the right place, every time.
Design that starts with the science
Irrigation design is not simply placing heads on a plan. It begins with a thorough understanding of the site — soil composition, topography, plant water requirements, microclimate variation, and available water pressure. From this foundation we build a hydraulic model that governs every design decision.
Our CAD drawings and hydraulic calculations are produced to a standard that supports contractor tendering, council submissions, and LEED or WELL documentation. Every design is a working engineering document, not just a layout.
Our design process
Site Survey & Analysis
We conduct a detailed site survey covering soil type, slope, sun exposure, plant species, and existing infrastructure. Water supply pressure and flow rates are measured at the point of connection.
Hydraulic Modeling
Using industry-leading software, we model the hydraulic performance of the proposed system — calculating pipe sizing, pressure losses, and flow rates across every zone to ensure uniform distribution.
CAD Design & Zoning
We produce detailed CAD drawings showing head placement, pipe routing, valve locations, and controller wiring. Zones are designed around plant type, exposure, and water requirement.
Scheduling Strategy
We develop a seasonal scheduling framework tailored to the site's plant palette and local climate — maximising efficiency and minimising water waste from the day the system is commissioned.
Why precision design matters
Eliminates over- and under-watering
Correctly zoned and calibrated systems apply water based on actual plant need — protecting plant health and reducing waste.
Reduces long-term operating costs
A well-designed system uses less water and requires fewer repairs. The upfront investment in design pays dividends across the system's lifetime.
Supports sustainability credentials
Our designs are produced to support LEED, WELL, and local water authority compliance requirements — providing the documentation needed for certification.
Contractor-ready documentation
Our CAD drawings and specifications are detailed enough for competitive tendering — ensuring contractors price accurately and install to the design intent.
Scalable for any site
From a private residential garden to a multi-hectare commercial estate, our design methodology scales to the complexity and ambition of the project.
Integrated with wider landscape design
We work closely with landscape architects and designers to ensure irrigation infrastructure is fully coordinated with planting plans, hard landscaping, and drainage.
