Irrigation System Design is the plan behind an installation: measurements, pressure and flow, zones, pipe layout, parts and room to expand. A good design lets installers quote on the same scope and avoids dry spots and weak zones later.
Describe your site once and compare irrigation design quotes.

How Design Connects to Installation
The installer follows the drawing, then confirms pressure on site and adjusts. You can get quotes from several installers on one design. To go straight to a design-and-install quote, see irrigation installation.
When Design Is Worth Paying For
- Large gardens, estates and commercial sites.
- Low or uncertain water supply.
- Phased installations.
- Sports fields and farms.
How It Works
- Send plans or photos and water details.
- Designer visits or works from plans.
- Draft layout reviewed with you.

Ballpark figures, not quotations. Ranges compiled from price guides published by South African irrigation, building-cost and quote websites, checked 19 October 2026 and rounded where needed. They are not our prices and no contractor is bound by them. No published South African guide we found prices residential design on its own. Many installers include design in the installation price. Published guides vary widely, so treat the ranges as a sanity check only. None of the sources state whether VAT is included, so confirm VAT on every quote.

Frequently Asked Questions
Do I need a separate design for a home garden?
Not always. Many installers include a layout in their quote. A separate design helps when comparing several quotes on the same scope.
Can I take a design to any installer?
Usually, if you have paid for it. Confirm ownership of the drawings first.
What information does a designer need?
Site measurements or a plan, planting, water source, and measured pressure and flow.
Does a design include a parts list?
It should. Ask for a bill of materials with head models, nozzles, valves, pipe sizes and controller.
