Irrigation Perth
Irrigation designed zone by zone
Every garden needs a different setup. We look at your garden's size, vegetation and watering needs, then design drip and sprinkler systems that give each zone exactly what it needs, and nothing it doesn't.

Why design matters
The right system grows a garden. The wrong one drowns it.
The wrong system
- Excess water and waterlogged ground
- Slippery, hazardous surfaces
- Insects drawn to soggy garden beds
- Over-watered plants that simply drown
Types of irrigation
Drip or spray? Usually both.
Two ways to water, each brilliant in the right place. Flip between them to see how they work.
Drip irrigation
Water drips slowly from emitters onto specific parts of the garden: a direct method that avoids waste.
- Best for
- Garden beds, shrubs, natives and vegetable patches.
- Why it works
- Water goes straight to the root zone, under the mulch
- Little lost to wind, overspray or run-off
- Each plant group gets its own steady drink
- Watch for
- Lines can be nicked when you dig, and emitters need the odd check.
Sprinkler irrigation
The more common method: water is sprayed across a zone through multiple sprinkler heads.
- Best for
- Lawns and larger open areas.
- Why it works
- Even coverage across turf
- Pop-ups sit flush with the grass when not running
- Easy to zone by sun and shade
- Watch for
- Arcs need setting so water lands on the garden, not paths and walls.
Hydrozoning
Group plants by thirst, water by station
Water Corporation recommends grouping plants with similar water needs together, so each irrigation station delivers the right amount to its zone. It's the heart of every system we design.
- 10 mm
About how much most Perth gardens need, twice a week in summer (Water Corporation).
- ~10 cm
Depth of chunky mulch recommended to cut evaporation, keep soil cool and suppress weeds.
- 9am · 6pm
Sprinklers run once on rostered days, before 9am or after 6pm, when less is lost to evaporation.

Questions, answered
Good to know
Drip or sprinklers: which do I need?
Usually both. Sprinklers suit lawns and larger open areas; drip suits garden beds, shrubs and vegetable patches. We evaluate your garden's size, vegetation and watering needs and recommend the right mix, station by station.
How much water does a Perth garden need?
Water Corporation's guidance is that most Perth gardens need about 10 mm of water twice a week in summer. How long that takes depends on your sprinkler type, which is exactly what we set up for you. Perth watering guide.
What happens if a system is the wrong size?
The wrong system can cause excess water, waterlogging and slippery surfaces, encourage insects and even drown plants. Correct sizing and design matter, which is why every system starts with an assessment.
Can I run my irrigation in winter?
Sprinklers must be switched off across Perth from 1 June to 31 August each year; hand watering is still allowed. Check Water Corporation for current rules and exemptions.
