Design a sprinklersystem in your browser.
Upload a site plan. Place rotors, sprays, MP rotators, and drip lines. Group them into zones with live GPM checks. Export a multi-page PDF report or a full bill of materials — all in your browser, free.
Educational estimate. Does not replace a licensed irrigation specialist. Verify pressure, flow, code, and freeze depth before installation.
Workflow
From floor plan to bill of materials in six steps
No CAD, no sign-up. The planner is built for the way real residential systems get designed.
- 1
Upload
Drop a site plan, blueprint, or satellite screenshot. Pan and zoom to fit.
- 2
Calibrate
Click two points on a known dimension (a curb panel, a wall) and enter the real length.
- 3
Outline
Trace turf areas, beds, and no-dig obstacles. They drive head sizing and routing.
- 4
Place
Drop rotors, sprays, MP rotators, and drip lines. Coverage arcs render live as you go.
- 5
Zone
Group heads into zones. The planner flags any zone that exceeds your POC capacity.
- 6
Export
PDF report, CSV bill of materials, or a full project JSON you can re-open later.
What it does
Every head, every zone, every part
Built around real Rain Bird parts and real residential hydraulics — not generic shapes.
Coverage modeling
Drag a head to resize its radius, rotate the wedge, or pin a 90 / 180 / 270 / 360 arc.
Hydraulic zoning
Zones split to your POC budget (default 10 GPM × 0.75 = 7.5 GPM per zone) with cap warnings.
Drip lines
Draw a polyline through a planting bed and the BOM gets 1/4" tubing + ET63-100S emitters.
Scale calibration
Two-click calibration handles any DPI. All radii, pipe lengths, and zone GPM stay accurate.
Real-SKU bill of materials
Heads match Rain Bird SKUs. Pipe, fittings, swing joints, valves, wire, boxes, and backflow.
Live coverage overlay
Translucent wedges add visually so gaps and over-spray pop instantly while you place heads.
Audience
Who Uses It
From a first-time DIY install to a designer presenting a package — the same tool, same data, same export.
Homeowner DIY
Plan your own yard, size a starter system, and walk into the supply house with a parts list.
Small Contractor
First-pass design before the site visit. Reuse defaults across jobs to estimate fast.
Landscape Designer
Present zone and coverage diagrams alongside planting plans for client-ready packages.
Sod & Lawn Care
Estimate watering coverage for new turf installs and overlay it on the client's plot map.
Output
Deliverables, not screenshots
Multi-page PDF report
Plan view, system overview, per-zone breakdown, and the full BOM — formatted for client review.
CSV bill of materials
SKU-level parts list including reducing fittings, swing joints, wire gauges, and valve boxes.
Project JSON
Round-trippable project file. Reopen the plan on another machine and pick up exactly where you left off.
FAQ
Frequently Asked Questions
What does the irrigation planner do?
Upload a site plan, calibrate the scale, paint your turf and obstacle polygons, mark the water tap and controller, and the planner auto-places sprinkler heads on a head-to-head triangular grid, splits them into zones sized to your available GPM, and produces a bill of materials.
What GPM and pressure should I enter?
Defaults are 10 GPM and 50 PSI — the median for North American residential service. For an accurate plan, measure your real supply with a bucket test at the hose bib and a gauge reading at full flow.
Does it support drip irrigation?
Yes. Drip lines are drawn as polylines that auto-compute tubing length and emitter count (Rain Bird ET63-100S at ~18 inch spacing). They live in their own zones with separate GPM accounting.
How are zones sized?
Zones are sized to an effective cap of min(POC GPM × 0.75, valve cap = 12 GPM). The planner refuses to mix rotor and spray heads on the same zone because their precipitation rates differ.
Is anything uploaded to a server?
No. Everything runs in your browser. Your site plan and design stay on your device via IndexedDB.
Can I export the plan?
Yes. Export a multi-page PDF report with the plan view, system overview, per-zone breakdown, and full bill of materials. A CSV BOM and a complete project JSON (round-trippable for re-importing later) are also available.
What about backflow, code, and frost depth?
The BOM includes a PVB backflow assembly line, 18 AWG multi-conductor control wire sized to the zone count, and jumbo valve boxes with gravel + geotextile. Verify local code, freeze depth, and backflow requirements with your municipality before installing — this tool is for planning, not as a substitute for a licensed irrigation specialist.
Educational estimate. Areaplane's irrigation planner is for learning and rough planning. It does not replace a licensed irrigation specialist. Always verify static pressure, available flow, local code, backflow requirements, and freeze depth before installation.
