Commercial Irrigation Systems water managed landscapes: office parks, residential estates, sectional title complexes, hotels, lodges, retail centres and similar properties. They need more zones, larger pipe, sturdier parts and schedules that work around people.
Describe your property once and compare commercial irrigation quotes.
Compare Commercial QuotesWhat Commercial Systems Include
- Site survey and design for the whole property.
- Main line sized for the flow needed.

- Central or cloud control, often with flow sensing.
- Pumps and tanks where supply is limited.
- As-built drawings and handover to the maintenance team.
Larger-Site Requirements
Operating schedules
Watering is planned around business hours, deliveries, events and guests, so walkways and parking stay dry when in use.
Maintenance access
Valves grouped in accessible boxes, labelled zones and isolation valves let maintenance teams work on one area without shutting everything down.
Durability
Vandal-resistant heads, deeper pipe under traffic areas and lockable controllers reduce damage.
Problems It Solves
- High water bills from undetected leaks.
- Patchy common areas.
- Wet walkways and parking.
- Controllers nobody knows how to change.
How Quotes and Work Proceed
- Send site plans, photos and a contact for access.
- Contractors survey the site and test supply.
- Design and itemised quote, sometimes phased.
- Compare scope and appoint.
- Installation, commissioning and as-built handover.
Requests are passed to independent contractors who take on this kind of work. Whether one is available depends on the job and the location.

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. Ranges cover supply and installation. Pumps, tanks, boreholes and civil work are usually extra. 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
Can irrigation run at night on a commercial site?
Yes, and it often should, so paths and parking are dry during the day. Check your municipality's current rules on watering times.
Who should own the controller on an estate?
The managing agent or body corporate, with a central or cloud controller so schedules can be changed without site visits.
Should a commercial system be metered?
A separate meter or flow sensor on the irrigation line makes leaks visible and helps with budgeting.
Can a system be installed in phases?
Yes. A master design lets sections be installed as budgets allow without redoing pipe later.
Is a maintenance contract necessary?
Not required, but large systems with many zones fail quietly without regular checks.
