No decision has been made yet. Water restrictions in Melbourne are possible over summer 2026–27, and the outcome depends on how full Melbourne's water storage is on 30 November. Storages were at 69.3% on 1 September, and water levels in Melbourne had edged up to 70% by 22 September. If storage stays between 60% and 75% on that date, the water corporations can bring in stage 1 or 2 restrictions to cut demand, although they don't have to. If it falls below 60%, restrictions become likely. The Bureau of Meteorology is forecasting below-average spring rain, with El Niño making lower inflows more likely, so the risk of water restrictions in Melbourne is higher than it has been since the last drought.
Whatever the storage level does, a lot of what drives your bill happens on your side of the meter.
Key takeaways
- The deciding reading is total storage on 30 November, and the Annual Water Outlook follows in early December.
- Melbourne hasn't had staged restrictions since the Millennium Drought.
- A bill well above 150 litres per person per day, with no change in habits, usually means a leak.
- Rainwater and recycled water are exempt from restrictions, but not if the tank is topped up from the mains.
- Hosing the driveway and running sprinklers at midday are already against the rules.
Will Melbourne have water restrictions this summer?
My read, as of late September: Melbourne will most likely finish spring in the 60% to 75% band. That makes stage 1 possible but not automatic, and puts stage 3 out of reach unless November is severe.
Melbourne's four water corporations place the city in an "outlook zone" based on total storage on 30 November, and that zone guides what happens from 1 December. In the "Be Proactive" zone, below 75% and down to 60%, the plan targets a 5% cut in demand. The tools include campaigns, voluntary reductions, efficiency programs, and stage 1 and/or stage 2 restrictions. Below 60%, in the "Act Now" zone, restrictions are considered likely, and stage 3 or 4 comes into play.
Some commenters believe dropping below 75% brings awareness campaigns and nothing more. That's half right. The campaign does come first, but stage 1 water restrictions are part of the same set of tools.
For storage to reach 60% by the end of November, it would need to fall about ten points in two months. Spring is normally when the reservoirs gain water. A hot, dry November could still change the picture, but a drop that large would be unusual.
The desalination plant doesn't give much room to move this year. The full 150 billion litre order for 2026–27 is already being delivered into the system, and that matches the plant's rated annual output.
Household use is being watched as closely as the storage figure. Residential use averaged around 159 litres per person per day over the past year, which is still above Target 150.
What would stage 1, 2 and 3 restrictions mean at home?
Each stage limits outdoor use of drinking water, mainly garden watering. None of them touches showering, washing or flushing.
The staged water restrictions Melbourne would use are written into each retailer's by-law. Those by-laws follow uniform state guidelines, with minor local variations, so water restrictions Victoria-wide share the same basic shape.
Under stage 1, watering systems can run on alternate days, from 6 am to 10 am or 6 pm to 10 pm, with odd and even house numbers taking turns. For most homes, stage 1 is the first of the watering restrictions Melbourne residents would notice, because the irrigation timer has to be reset.
Stage 2 water restrictions go further. Lawns can't be watered at all, and gardens get only 6 am to 8 am and 6 pm to 8 pm on alternate days. Stage 3 water restrictions limit gardens to drippers on alternate mornings between 6 am and 8 am, and residential pools can't be filled.
If you remember the Millennium Drought water restrictions, you'll remember stage 3a. It started on 1 April 2007 and limited hose watering to two mornings a week, between 6 am and 8 am. Melbourne moved back to stage 2 on 1 September 2010.
You don't need to track Yarra Valley Water restrictions or South East Water restrictions separately. The retailers coordinate with Melbourne Water so the same stage applies across the city, which keeps Melbourne water restrictions consistent from Werribee to Frankston.
Why is my water use over 150 litres when nothing has changed?
The most likely cause is a leak you can't see, usually a toilet cistern or an underground supply pipe.
Many people in online discussions sit well under the target without trying. One household reported 105 litres per person on its latest bill, and several couldn't understand how anyone goes over. Big gardens and pools explain part of the gap. The rest often comes from water escaping somewhere nobody is looking.
Here are the common causes, roughly in the order we find them:
- Toilet cisterns that keep running into the bowl. Put a few drops of food colouring in the cistern and don't flush. If colour appears in the bowl within 20 minutes, a valve is leaking.
- Dripping taps, especially outdoor taps hidden behind garden beds.
- Hot water relief valves that won't stop discharging. A short release while the tank heats up is normal. A steady flow usually means mains pressure is too high or the valve has failed, and that repair is for a licensed plumber.
- Underground leaks between the meter and the house. Reactive clay in the western and northern suburbs swells and shrinks with the seasons and stresses older pipework. Many inner-suburb period homes still have galvanised steel supply lines that corrode from the inside.
The meter test takes about an hour. Turn off every tap and water-using appliance, including irrigation timers and any tank pump. Write down the full meter reading, including the red digits, and don't use any water for at least an hour. If the reading has changed, water is leaving the system somewhere.
If the meter moves but you can't see a drip, the leak is usually underground, in a wall or under a slab. Electronic leak detection finds the spot before anyone lifts tiles or digs a trench.
A bill that keeps rising quarter after quarter is one of the easier signs of a hidden leak to miss, and you pay for that water whether restrictions arrive or not.
Does a 4-minute shower save more than a new shower head?
Not always. An old high-flow head can use more water in four minutes than a WELS-rated head uses in eight.
Many Melbourne bathroom drawers still have the timers and hourglasses from the last drought. A timer only controls the minutes. Some older heads put out 25 litres a minute. A 3-star WELS head is capped at 9 litres, and a 4-star head at 7.5. Four minutes under a 20-litre head uses 80 litres. Eight minutes under a 4-star head uses 60.
To check your own, hold a bucket under the shower for ten seconds and multiply the amount by six. Anything above 9 litres a minute should be replaced. A new head takes minutes to fit and reduces the energy used to heat water as well.
Landlords have a deadline coming. From 1 March 2027, a shower head rated at least 4-star WELS must be installed at the start of each new lease. The same regulations bring in the 1 March 2027 rule for gas hot water systems that reach the end of their life.
Do water restrictions apply to purple recycled water taps?
No. Restrictions and the permanent rules apply only to drinking water. Recycled water is exempt as long as it isn't mixed with mains water.
That confirms what one commenter from a newer estate assumed about their garden and car washing. Recycled water from a purple tap or pipe is approved for toilets and gardens, and on many estates for the washing machine as well. Never use it for drinking or filling a pool.
The bigger risk is in the plumbing itself. If a recycled water line is cross-connected to the drinking supply, treated wastewater can reach a kitchen tap. Any change to recycled pipework, including a renovation that moves a toilet or laundry, is licensed work.
Older suburbs don't have this third-pipe network, and that's where rainwater tanks come in.
Is a rainwater tank worth plumbing into the house?
For most homes with room for one, yes. A tank connected to the toilet and laundry is used every day of the year. A garden-only tank sits full through winter and runs dry in the hottest weeks.
People who installed tanks in the last drought mostly haven't regretted it, and the billing data supports them. A Swinburne study of 6,390 Melbourne homes, using Yarra Valley Water data, found tanks saved an average of 137 litres a day. A 5,000-litre tank supplying the garden and the laundry or toilet paid for itself fastest.
One detail catches people out. If a tank is topped up with mains water, restrictions apply to everything in it. A mains switchover device avoids this. When the tank runs low, it sends mains water straight to the toilet or laundry without refilling the tank.
A tank connected to the house needs backflow prevention, and that switchover device, and both must be installed by a licensed plumber under the Plumbing Regulations 2018 (Vic) and AS/NZS 3500. Rebates have come and gone over the years, so ask your water retailer before you buy.
What do the Permanent Water Saving Rules already ban?
They ban hosing down driveways and paths, and running sprinklers between 10 am and 6 pm. These rules apply every day across Victoria.
Neighbours hosing driveways and sprinklers running at midday were the most common complaints. Both already break the current water restrictions Melbourne has in place. Every hose needs a trigger nozzle. Watering systems can only run from 6 pm to 10 am. Hard surfaces can only be cleaned in limited cases, such as after an accident or during construction. You can hand-water with a hose, watering can or bucket at any time.
Several commenters suggested Melbourne should stay on stage 1 permanently. The permanent water saving rules already cover much of what stage 1 would add, apart from the alternate-day roster.
For gardens, the plumbing answer is drip irrigation on a timer. Yarra Valley Water describes sub-surface drip hose on an overnight timer as the most efficient setup. It also keeps a garden alive under the watering restrictions Melbourne would introduce at stage 1 or 2.
A few people asked why households always get the message. Fair question. Your own use is the part you control, and it's also the part that shows up on your bill.
If you're replacing gas hot water, should you look at water use too?
Yes. Both jobs involve the same parts of the house, so one visit can cover them.
One detailed comment proposed upgrading whole streets at once, with recycled water to toilets and laundries and every home converted to all-electric. That's a decision for government. For a single house, the timing works well already. From 1 March 2027, a gas hot water system at end of life has to be replaced with an electric one. When you book that replacement, we can check mains pressure and replace old shower heads on the same visit.
What should Melbourne homeowners do before 30 November?
Fix leaks, check shower heads and irrigation, and arrange any tank connection in spring.
One commenter described three groups: people who never stopped saving after the last drought, people who'll pick it up again quickly, and people who notice six months after restrictions start. The plumbing work suits the first group's timing. Spring is quieter than the weeks after an announcement, when every plumber in the city is getting the same calls.
If your bill has climbed without an explanation, or you want a tank or drip system connected before summer, book a leak check or quote with Jacksons Local Plumbing. We'll run the meter test, find where the water is going and tell you plainly what needs fixing.
Frequently asked questions
Are there water restrictions in Melbourne right now?
No. Only the Permanent Water Saving Rules apply, and no staged Melbourne water restrictions have been announced for summer.
Are any towns on water restrictions in Victoria in 2026?
One system. Most water restrictions Victoria has seen in 2026 have been in regional areas, and as of mid-September, every town was on the permanent rules except those supplied by the Forest Hill system in Central Highlands Water's area, which is on stage 3. Check your regional water corporation for current Victoria water restrictions outside Melbourne.
When will we know if restrictions are coming?
Early December. Melbourne's Annual Water Outlook 2027 is due that month.
Do restrictions apply to my rainwater tank?
Only if the tank is topped up with mains water.
Can I still fill my pool?
Yes. The permanent rules place no limit on filling or topping up pools. Stage 2 limits filling to small pools unless you have an approved Water Use Plan, and Stage 3 stops it entirely. If a refill is due, do it before summer.
