Your lawn might look healthy, but is your reticulation system using more water than it needs?
A leaking underground pipe, poorly positioned sprinkler or outdated watering schedule can waste water without immediately affecting the appearance of your garden. In fact, many irrigation problems go unnoticed until dry patches appear, water begins pooling or the system stops working altogether.
For Perth homeowners, water-efficient reticulation is particularly important. Hot, dry summers, changing seasonal conditions and local watering restrictions mean irrigation systems need to be properly maintained and programmed.
The good news? You don’t necessarily need to replace your entire irrigation system to improve its efficiency.
At TLC Reticulation, we help Perth property owners identify reticulation faults, repair damaged components and improve irrigation management through professional servicing and controller upgrades, including Hunter smart irrigation technology.
Here are five practical ways to reduce water waste while keeping your lawn and garden healthy.
What Are the 5 Best Ways to Save Water With Reticulation in Perth?
An efficient reticulation system should deliver the right amount of water to the intended areas without unnecessary leaks, overspray or excessive watering.
The following five improvements can help reduce avoidable water consumption.
| Water-saving method | Why it matters | Recommended action |
| Repair underground leaks | Damaged pipes and valves can waste water | Inspect and repair leaking components |
| Improve sprinkler coverage | Misaligned sprinklers can water unwanted areas | Adjust nozzles, pressure and sprinkler positioning |
| Upgrade to a smart controller | Fixed schedules may not reflect changing weather | Consider a Hunter Hydrawise-compatible controller |
| Adjust seasonal watering schedules | Gardens need different amounts of water throughout the year | Follow Perth watering rules and seasonal guidance |
| Maintain the reticulation system | Minor faults can become more serious over time | Arrange routine inspections and repairs |
Way 1: Find and Repair Hidden Underground Reticulation Leaks
Could your reticulation system be losing water before it even reaches the sprinklers?
Underground pipe leaks are a common cause of irrigation water loss.
Reticulation pipes and fittings can become damaged through landscaping work, ground movement, ageing components or accidental excavation.
Because much of the pipework is buried, leaks are not always immediately visible.
Warning Signs of an Underground Reticulation Leak
Look for:
- Unexplained wet patches on the lawn
- Water pooling near sprinkler heads or garden beds
- Unusually soft or muddy soil
- Reduced water pressure
- Sprinklers producing weaker spray patterns
- Unexpected increases in scheme-water consumption
A damaged solenoid valve can also allow water to pass through when a zone should be switched off.
Even a relatively small leak can waste significant amounts of water if it continues unnoticed.
How Can You Check for Reticulation Leaks?
Start by inspecting accessible sprinkler heads and visible pipe connections.
If your system uses scheme water, check whether your water meter indicates consumption when all water-using fixtures and appliances are switched off. This can help identify a possible leak, although it will not necessarily establish whether the reticulation system is responsible.
For bore-fed irrigation, investigate unusual pressure changes, persistent wet patches and unexpected pump operation.
Recommended action: Turn off the affected irrigation zone or water supply where practical and arrange professional fault finding.
TLC Reticulation provides underground pipe repairs, solenoid valve locating and irrigation fault finding across Perth.

Way 2: Improve Sprinkler Coverage and Water Pressure
Your sprinklers may be operating on schedule, but are they watering the right areas?
Poor sprinkler coverage can result in one section of your lawn receiving too much water while another remains dry.
This often leads homeowners to increase watering times, even though the underlying problem may be a damaged sprinkler or incorrect system configuration.
Common Causes of Inefficient Sprinkler Coverage
- Blocked sprinkler nozzles
- Damaged or sunken sprinkler heads
- Incorrect sprinkler positioning
- Excessive overspray onto pathways or driveways
- Inconsistent water pressure
- Mismatched sprinkler types
- Too many sprinklers operating on one irrigation zone
For example, a sprinkler positioned too close to a pathway may direct part of its spray onto concrete instead of the lawn.
Increasing its run time will not correct the problem. It will simply continue watering the wrong area for longer.
How Can You Improve Sprinkler Efficiency?
Start by checking whether each sprinkler delivers water to its intended area.
Look for dry patches, overspray, blocked nozzles and damaged sprinkler heads.
Where necessary, the system may benefit from:
- Sprinkler head replacement
- Nozzle cleaning or adjustment
- Pressure testing
- Correcting sprinkler alignment
- Improving irrigation zone configuration
- Replacing unsuitable components
TLC Reticulation works with quality irrigation products, including Hunter sprinkler components, to help improve system performance.
A professional inspection can determine whether the problem requires a simple adjustment or more extensive repairs.
Way 3: Upgrade to a Hunter Hydrawise Smart Irrigation Controller
What if your reticulation system could adjust its watering schedule when the weather changes?
Traditional irrigation controllers operate according to programmed schedules.
While these controllers can be reliable, their settings often remain unchanged until someone manually adjusts them.
This means a system may continue watering for the same duration even when temperatures drop or rainfall reduces the garden’s irrigation requirements.
Smart irrigation controllers provide more flexibility.
What Is Hunter Hydrawise?
Hunter Hydrawise is smart irrigation management software designed for compatible Hunter irrigation controllers.
It allows property owners to manage irrigation schedules through a smartphone or web browser.
Can Hunter Hydrawise Actually Save Water?
Yes, a correctly configured smart irrigation controller can help reduce unnecessary watering.
For example, if a fixed timer continues operating after rainfall, water may be applied when the soil already has sufficient moisture.
A Hydrawise-compatible controller can respond to selected weather conditions and adjust the schedule accordingly.
However, actual savings depend on the property’s existing watering habits, controller settings, landscape requirements and system condition.
A smart controller cannot repair a leaking underground pipe or correct poorly positioned sprinklers.
TLC Reticulation supplies and installs Hunter irrigation controllers and can assist with suitable Hydrawise-compatible upgrades.
See our Reticulation Controllers page for more information.
Way 4: Adjust Your Watering Schedule for Perth’s Climate
Are you still using the same reticulation settings you programmed during summer?
Perth gardens do not require the same amount of water throughout the year.
Higher summer temperatures and evaporation can increase irrigation demand, while cooler conditions and seasonal rainfall generally reduce the need for supplementary watering.
According to Water Corporation, adjusting irrigation schedules throughout the year helps avoid unnecessary watering.
Water Corporation’s Seasonal Adjustment Guide
Water Corporation provides the following general seasonal adjustment recommendations for Perth and the South West.
| Month | Recommended seasonal adjustment |
| January-February | 100% |
| March | 80% |
| April | 60% |
| May | Manual watering if needed |
| June-August | Winter sprinkler switch-off |
| September | Manual watering if needed |
| October | 60% |
| November | 80% |
| December | 90% |
These percentages are seasonal adjustments to an appropriately configured base watering programme, not percentages of a property’s total water allocation.
Actual watering requirements depend on the landscape, sprinkler type, soil conditions and applicable restrictions.
Understand Perth’s Rostered Watering Days
Perth properties are subject to watering restrictions.
For most residential properties, sprinkler use is limited to designated watering days and generally must occur once before 9 am or after 6 pm, subject to applicable rules and exemptions.
Your permitted days depend on your property details and water source.
Check your schedule using Water Corporation’s watering day checker.
Why Controller Settings Matter
Incorrectly configured controllers can lead to:
- Unnecessary watering after rainfall
- Excessively long irrigation cycles
- Overlapping watering programmes
- Sprinklers operating outside permitted times
- Watering schedules that do not reflect seasonal conditions
TLC Reticulation can assist with controller installation, programming and troubleshooting to help property owners manage irrigation more effectively.
Way 5: Schedule Regular Reticulation Maintenance
Your reticulation system may be operating normally today, but that does not mean every component is performing efficiently.
Over time, sprinkler heads can become blocked, underground fittings may develop leaks and valves can begin malfunctioning.
Routine maintenance helps identify these problems before they cause significant water loss or affect your landscaping.
How Often Should Reticulation Be Serviced?
An annual reticulation inspection is a practical starting point for many Perth residential properties.
However, systems with recurring faults, heavy use or complex landscaping may require more frequent attention.
Late winter or early spring can be a useful time to arrange an inspection before warmer weather increases irrigation demand.
Any testing must comply with applicable watering restrictions and maintenance-testing requirements.
TLC Reticulation provides professional reticulation servicing and fault finding to help maintain reliable irrigation systems.
When Should You Call a Reticulation Specialist?
Basic maintenance, such as checking visible sprinkler alignment or reviewing controller schedules, can help identify straightforward problems.
However, some faults require professional equipment and diagnosis.
Arrange a reticulation inspection if you notice:
- Persistent wet patches or pooling water
- Sprinklers that continue running after the controller switches off
- Multiple irrigation zones activating unexpectedly
- Repeated low-pressure problems
- Underground pipe leaks
- Controller errors that do not clear
- Irrigation zones failing to activate
- Recurring faults after previous repairs
