Lawn sprinkler system
from$2,400
- Up to four zones of pop up sprays and rotors
- Heads spaced so each one reaches the next
- Controller with a rain sensor
- Turf lifted and relaid along every trench
Water where the roots are, and nowhere else
Greenflow designs, installs and repairs sprinkler and drip systems for home gardens, orchards and farms. Every system is zoned by sun, soil and planting, then set to the watering rules where you live.

Systems we design and install
Each price includes the design visit, the pipe, the heads or drippers, the valves and a controller, fitted and tested. The final figure follows a pressure and flow test at your tap or pump.
Garden drip system
from$950
- Pressure compensating drippers for even flow
- Filter and pressure regulator at the tap
- Lines hidden under mulch
- Separate zone for pots and planters
Orchard and farm drip
a hectare, from$2,900
- Mainline, submains and drip laterals
- Sand or disc filtration for the source
- Injector point for fertiliser
- Flush valves at the end of each block
A deposit of 30 percent confirms the installation date once you accept the written quote. The balance is due at handover, paid directly to us.
Repairs and servicing
We repair systems whoever fitted them. Prices cover labour and standard parts for a home system, and we confirm the cost on site before we dig.
Broken sprinkler heads
Heads cracked by mowers, cars or frost replaced and raised to the right height, then the spray pattern trimmed to stay off paths.
Per headfrom $45
Leaks and wet patches
A soggy patch or a water bill that jumped usually means a split pipe or a loose fitting. We find it, dig small and repair it.
Leak repairfrom $85
Valves that stick open
Zones that run on after the controller stops, or never start, get the valve diaphragm, solenoid or wiring repaired.
Per valvefrom $120
Controller faults
Blank screens, lost programmes and wiring faults traced, or the controller replaced with one that reads a rain or soil sensor.
Diagnosisfrom $95
Blocked drip lines
Lines flushed, clogged emitters replaced and the filter cleaned, so the end of the row gets as much as the start.
Per zonefrom $75
Season start and shut down
Each zone run and adjusted at the start of the dry season, and the system drained before frost where winters freeze.
Per visitfrom $110
Repair visits within 60 km cost $60, and that charge comes off the bill when the repair is done on the same visit.
From the first visit to the first watering
A home system usually takes two to three weeks from the site visit to handover. Farm projects are scheduled around planting.
Site visit
We measure the area, test pressure and flow at the tap or pump, check the soil and note where sun and shade fall.
Zone plan and quote
You receive a drawn zone plan and a written quote line by line, with the water each zone needs per week.
Installation
Narrow trenches, pipe and valves, then every line is pressure tested before the trench is closed and the turf relaid.
Handover
We walk each zone with you, set the controller to the season and the local rules, and leave a copy of the plan.
Drip for orchards, vines and market gardens
On a farm, the design starts at the water source. We size the pump, the filters and the mainline for what a borehole, dam, river or tank can supply, then split the land into blocks that can run in turn.
Drip puts water at the root zone with little lost to wind or evaporation, which matters most where water is scarce or metered. Fertiliser can be added through the same lines in measured doses.
- Flow and pressure worked out block by block
- Filters matched to sandy, silty or dam water
- Pumps sized for borehole, tank or river supply
- Training for the farm team at handover
Watering within the local rules
Rules on garden and farm watering differ from one country to the next and often from one season to the next. Some water authorities limit the days or hours a sprinkler may run, some ban hoses and sprinklers in a drought, and many require a backflow device where irrigation joins the mains.
We check the rules that apply at your address before we design, and set the controller so it follows them. When restrictions change, a quick visit or a phone call is usually enough to adjust the programme.
- Controller set to the permitted days and hours
- Rain sensor that pauses watering after a shower
- Soil moisture sensors on request
- Backflow protection where the mains supply needs it
A starting schedule for each kind of planting
These are the starting points our technicians set in warm, dry weather. We then adjust them to the soil, the slope and the rules where you live.
| Planting | What waters it | Starting point in warm weather |
|---|---|---|
| Lawn in full sun | Pop up sprays or rotors | Early morning, two or three times a week |
| Lawn in part shade | Rotors on a separate zone | Early morning, about half the sunny lawn time |
| Shrubs and borders | Inline drip under mulch | Once or twice a week, a long slow run |
| Young trees | Two drippers or a bubbler per tree | Twice a week in the first summer |
| Vegetable beds | Drip tape along each row | Short runs most days while plants are young |
| Pots and planters | One micro dripper per pot | Daily in hot weather, on its own zone |
Clay soils take water slowly and suit shorter runs repeated, while sandy soils drain fast and suit more frequent watering.

Lawns, beds, patios and farm blocks we have planned and fitted.
From gardens and farms we water (example reviews)
The lawn used to be green by the house and brown by the fence. After the redesign the whole lawn looks the same, and the water bill went down over the summer.
They sized the filters for our dam water and showed the farm team how to clean them. Two seasons on, the end of each row still gets its share.
When the watering days changed in the dry season, one call and the controller was reset the same afternoon. Clear advice and tidy trenches.
Questions about irrigation
Is a permit needed to irrigate?
It depends on the country and the source. Home gardens on the mains rarely need a permit, though many places require a backflow device. Taking water from a borehole, river or dam for a farm often needs a licence from the water authority, and we tell you what to check before we design.
Can the system run from a tank or a borehole?
Yes. We size a pump and a pressure tank for the supply, and on a borehole we design zones that never draw more than the borehole can deliver.
Will the lawn be dug up?
Only along narrow trenches. Turf is lifted, set aside and relaid the same day, and the lines settle back within two or three weeks of normal watering.
What happens when it rains?
A rain sensor pauses the programme after a real shower and lets it resume once the ground dries. Soil moisture sensors can be added for beds and farm blocks.
Do you repair systems fitted by someone else?
Yes. Most of our repair work is on systems we did not install. We find the valves, trace the zones and leave a simple plan of what we found.
How long do the parts last?
Buried pipe lasts for decades when it is protected from frost and sun. Heads and drippers wear faster, and a yearly check catches the ones that need changing.
