From full zone audits with distribution uniformity scoring, to simple run time calculators — these tools are built around Perth's sandy soils and the systems our technicians work on every day.
Calculate precipitation rate and distribution uniformity from catch can volumes. Full DU scoring with low-quarter analysis.
→ Trade // 02mm/hr from head type and spacing. Square, triangular, and rectangular patterns with flow presets.
→ Trade // 03Time a bucket fill and get instantaneous flow rate in L/min, L/hr, and GPM. Live gauge with high-flow alert.
→How long to run your reticulation? Enter precipitation rate and soil type for a precise runtime with cycle-and-soak recommendations.
→ External // 05Check your two-day-a-week roster by house number under current Water Corporation restrictions.
↗Built for Perth conditions
Sandy soils, bore water quality, and Water Corporation restrictions are factored into every calculator on this site.
For trades and homeowners
Full zone audits with DU scoring down to simple runtime calculators — tools for every level of irrigation knowledge.
About these calculators
Who builds these tools?
Built and maintained by Retic Man, a Perth-based reticulation and bore pump contractor operating across the metro area and hills. We build tools we actually use in the field.
Are they accurate?
All formulas follow standard irrigation engineering principles. Results are as accurate as the inputs — field conditions like wind, pressure variation, and head wear will always introduce variance. Use these as a professional starting point, not a substitute for on-site measurement.
What's coming next?
A zone flow calculator for pipe sizing and pump selection, and a soil wetting agent dose calculator. If there's a tool you'd find useful, get in touch.
