Waterwise rebates in Perth, explained
Water Corporation runs the long-standing Waterwise programto help Western Australians use less scheme water. Over the years that has included various rebates and incentives – on things like efficient irrigation, soil wetters and waterwise plants – alongside the year-round sprinkler roster that sets when you can water.
Rebate offers and amounts change from season to season, so the current detail always lives with Water Corporation’s waterwise offers. What doesn’t change is the thing that actually saves you water and money: a correctly designed, efficiently programmed system. That’s what we build – and as a Waterwise-endorsed businessand Irrigation Australia member, it’s exactly what any waterwise program is looking for.
Perth sits on one of the driest, most water-stressed corners of the country. With a drying climate and a growing population, scheme water is a genuinely finite resource – which is why Water Corporation puts so much weight behind the Waterwise program rather than simply selling more water. The program is less a single rebate and more a whole framework: a year-round watering roster, a winter switch-off, public education, a network of endorsed irrigation businesses and garden centres, and rotating incentives aimed at the products and behaviours that cut the most waste. Understanding how those pieces fit together is what lets you run a green garden on noticeably less water.
On this page we walk through the parts that stay relatively stable – the roster, the winter switch-off, leak allowances, and the design and equipment choices that make a system efficient – and point you to Water Corporation for the figures and offers that change. The short version: the single biggest lever on your water bill is how your system is designed and programmed, not which rebate happens to be running this month.
What the Waterwise program covers
Rather than chase a single dollar figure that may already be out of date, it helps to think in terms of the categories the program has supported over the years. The table below is a guide to the kinds of things that have featured – always confirm the current offers, amounts and eligibility with Water Corporation’s Waterwise program.
| Area | What it’s about | How we help |
|---|---|---|
| Efficient irrigation | Upgrading to water-efficient sprinklers, nozzles and controllers that deliver even coverage and waste less. | We design and install efficient systems and can retrofit pressure-regulated, matched-precipitation nozzles to an existing one. |
| Smart controllers | Weather-based and WiFi controllers that adjust watering to conditions and the roster instead of running a fixed schedule. | We supply, install and program smart and WiFi controllers from trusted brands. |
| Soil wetters & mulch | Treating Perth’s water-repellent sandy soils so water soaks in, and mulching to slow evaporation. | We advise on what suits your soil as part of an efficient system design. |
| Waterwise plants | Choosing low-water and native species and grouping them by water need (hydrozoning). | We zone your system by water need so each plant group gets the right run time. |
| Leak allowances | A possible credit toward a high bill caused by a hidden, hard-to-detect leak once it’s been repaired. | We find and fix leaks fast and can document the repair for your claim. |
Notice the pattern: almost every category rewards the same thing – a system that’s efficient by design. Get that right and you benefit whether or not a specific rebate is open, because the savings come off every quarter’s bill, not just once.
Who qualifies and how to claim
Eligibility and the claim process depend on the specific offer and change over time, so the authoritative source is always Water Corporation. As a general guide, most household waterwise incentives are open to residential scheme-water customers, often ask you to buy from a participating retailer or use an endorsed installer, and require proof of purchase. The practical steps usually look like this:
- Check the current offers, amounts and conditions on Water Corporation’s waterwise offers before you buy or book, so your purchase qualifies.
- Choose eligible products and, where it matters, a Waterwise-endorsed installer – that’s us. Using an endorsed business is exactly the kind of box these programs like to see ticked.
- Keep your receipts and any installation paperwork – we can provide a job record.
- Submit the claim per Water Corporation’s current method (online form or retailer).
Because we can’t guarantee a third party’s programs, we won’t promise a specific rebate – but we will make sure the work we do is the efficient, endorsed standard those programs are built around, and we’ll give you the documentation to support a claim.
Leak allowances explained
A hidden leak is one of the few things that can blow out a water bill overnight – a cracked underground pipe, a solenoid stuck part-open, or a fitting weeping into the soil where you’ll never see it. Because the water disappears below ground, you often only find out when the bill arrives. Separate from the waterwise rebates, Water Corporation has long run a leak-allowance schemethat may credit part of a bill inflated by a concealed, hard-to-detect leak – but only once the leak has been repaired, and subject to its current rules and evidence requirements.
The eligibility criteria, the evidence you need (typically proof the leak was concealed and has been fixed) and the time window all sit with Water Corporation, so confirm the details on Water Corporation’s leak allowance page. Whatever the outcome of a claim, the urgent priority is the same: get the leak found and stopped before it costs you any more. Our technicians locate and repair leaks across Perth and can document the repair for your records – book a reticulation repair and we’ll get it sorted.
Smart controllers, soil wetters & the basics of an efficient system
The fastest way to use less water without a browner garden is to stop watering when you don’t need to and to make sure every drop that comes out is doing useful work. That comes down to a handful of design and equipment choices:
- Smart & WiFi controllers. A weather-based or WiFi controller can skip or shorten a cycle when rain is forecast, adjust seasonally, and let you make changes from your phone. It also makes it effortless to stay on your rostered days and respect the winter switch-off. See our installation page for how controllers fit a new system.
- Pressure regulation & the right nozzles. Too much pressure creates fine mist that drifts away on the breeze. Pressure-regulated heads and matched-precipitation nozzles put water on the ground where it belongs and keep coverage even across a station.
- Hydrozoning.Grouping plants by water need – lawn, established natives, pots and beds each on their own station – means nothing gets over-watered just to keep something thirstier alive.
- Soil wetters & mulch.Perth’s sandy soils repel water once they dry out. A seasonal wetting agent helps water soak in instead of running off, and mulch slows evaporation so what you apply lasts longer.
None of this is exotic – it’s the standard way we design every system. The payoff is a garden that stays healthy on less water, a smaller bill, and a system that already meets the efficiency bar any waterwise program is looking for.
The Perth sprinkler roster & winter switch-off
Water Corporation sets a rostered number of watering days based on your water source and address, and the winter sprinkler switch-off (1 June to 31 August)applies to both scheme and garden bore sprinklers – bores aren’t exempt. The roster is updated periodically, so confirm your days for your address with Water Corporation.
The easy part: when we install or service your system, we program your controller to match whatever roster applies– so you water on the right days, at the right times, without breaking the rules. For more, see our guides on Perth watering days and the winter sprinkler switch-off.

Water Corporation Rebate & Waterwise FAQs
Water Corporation runs the Waterwise program and from time to time offers waterwise rebates and incentives — these have included things like efficient irrigation upgrades, soil wetters and waterwise plants. Programs and amounts change, so always check Water Corporation's current waterwise offers. What stays constant is that an efficient, correctly-designed system is what qualifies you and saves you the most on water — that's what we build. See current Water Corporation waterwise offers→
Water Corporation sets a rostered number of watering days based on your water source (scheme/mains or garden bore) and your address. The winter sprinkler switch-off (1 June to 31 August) applies to scheme and bore sprinklers alike. Rosters can change, so confirm your days with Water Corporation — and we program your controller to match whatever applies to your property. Check your watering days→
A waterwise system is designed and programmed to deliver only the water your garden needs — the right sprinklers and nozzles for even coverage, pressure regulated correctly, zones grouped by water need, and a controller set to the current roster. It keeps your lawn healthy while cutting waste (and your water bill).
Yes — Perth Reticulation Experts is Waterwise-endorsed and a member of Irrigation Australia. Every system we install is designed to run efficiently and meet waterwise standards, which is exactly what you want when accessing any Water Corporation waterwise program.
Yes. A modern controller (including WiFi models you can run from your phone) makes it easy to water on your rostered days, adjust run times by season, and avoid over-watering. We supply, install and program controllers as part of a new system or as an upgrade to your existing one.
Separate from the waterwise rebates, Water Corporation offers a leak allowance that can credit part of a high bill caused by a concealed, hard-to-detect leak once it has been repaired — handy if a burst reticulation line or a failed solenoid quietly ran up your usage. Eligibility, evidence and the claim window are set by Water Corporation, so check their leak allowance page for the current rules. The practical first step is the same either way: get the leak found and fixed. We locate and repair leaks across Perth, and we can document the repair for your records.

Yes — Perth's sandy, water-repellent soils shed water before plant roots can use it, so even a perfectly programmed system wastes water on hydrophobic ground. A seasonal soil wetter helps water soak in rather than run off, and a good layer of mulch slows evaporation. Both have featured in waterwise advice and incentives over the years. We'll point you to what suits your soil as part of designing an efficient system.
Hydrozoning means grouping plants with similar water needs onto the same station so each zone can be watered for the right length of time — lawn on one station, established natives on another, pots and veggie beds on their own. It's a core waterwise design principle because it stops you over-watering the thirsty plants just to keep the hardy ones alive. We design zones this way as standard, which is one of the biggest practical water savings on a property.
Yes. The winter sprinkler switch-off (1 June to 31 August) applies to both scheme (mains) and garden bore sprinklers across Perth, Mandurah and parts of the South West — bores aren't exempt. Hand-watering is still allowed during the switch-off, and a few limited exemptions exist, so check the current rules with Water Corporation. Whatever applies to your property, we program your controller so it pauses over winter and runs on the correct days automatically. Winter Sprinkler Switch-off details→
