Can you pressure clean a driveway in Sydney
Usually yes, and not for the reason most people assume. Cleaning a driveway, a path or any paved area with drinking water is permitted where the cleaning is necessary for safety, health, an emergency, construction activity or surface contamination. Washing one simply to make it look newer is on the prohibited list.
Washing the building is different again. Walls, windows, gutters and roofing may be washed at any time. It is the flat paved ground that carries the test, and that is the part almost nobody gets told.
The rule, in its own words
The instrument is a notice of water restrictions gazetted on 1 December 2020 under the Sydney Water Act 1994, in force until further notice. Sydney Water calls the guidelines mandatory and says they apply every day of the year. Two passages matter.
Prohibited: the hosing of paths, driveways, concrete or other paved areas.
Permitted: cleaning of paths, driveways, concrete or other paved areas when cleaning with water is necessary for reasons of safety, health, emergency, construction activity (including resurfacing) or surface contamination.
The notice then adds an equipment condition for water used under that category: a hose must have a trigger nozzle, unless it is supplying high pressure water cleaning equipment. That single sentence is where the disagreement lives.
Two ways that sentence gets read
Both readings are held by people in this trade. They lead to different jobs being accepted, which is why it is worth setting them out rather than picking one quietly.
The narrow reading
The purpose test governs. Drinking water may be used on a path, a driveway, concrete or paving only where cleaning with water is necessary for one of the listed reasons. The sentence about equipment sets a condition on water already being used under that category: a hose needs a trigger nozzle unless it is supplying high pressure cleaning equipment. On this reading the equipment does not unlock anything. A wash with no listed reason behind it is not permitted whatever machine is pointed at it.
This is the one we work to.
The broad reading
The guideline names high pressure water cleaning equipment as an accepted method for hard surfaces, and read on its own that sentence can be taken as putting professional high pressure work outside the plain hosing prohibition altogether. Operators who read it this way treat the machine as the permission.
We do not rely on this one.
Why we take the narrower one
Because a job that satisfies the narrow reading satisfies the broad one as well. Work to the broad reading and you are exposed the moment someone reads the notice the other way. Work to the narrow reading and both readings agree with you.
In practice that means one habit: the reason for cleaning goes on the job sheet before the work starts, with photographs of the surface it refers to. It costs nothing and it is the only version of this that is correct either way.
What counts as a reason
The categories are the notice's. The everyday examples underneath them are ours, and they are the ones most of our hard surface work sits under.
- Safety
- Algae, moss and lichen turning a path, a ramp or a driveway slippery. This is the commonest one by a distance, and it is the reason most people call about without knowing it.
- Surface contamination
- Oil, fuel and hydrocarbon staining on a driveway, a workshop floor or a loading dock. Contamination is the reason, and removing it is also what stops it washing into a drain in the next storm.
- Health
- Organic build up around bin bays, back of house concrete and drains, where the mess itself is the problem.
- Construction activity
- Cleaning down before or after building work, including resurfacing, which the guideline names in its own words.
And what does not
Making a clean driveway look newer. A hard surface with nothing wrong with it, washed with drinking water because the owner wants it brighter, does not sit under any of the listed categories. That is the job we either move onto tank water or decline.
This is the least popular paragraph on our site and it is staying. A trade that will not say what it turns down is not telling you much about what it accepts.
There is a straightforward way through it. Rainwater and recycled water sit outside the guidelines altogether, provided the tank is not topped up from the drinking water supply. A cosmetic wash off a tank is a different question from a cosmetic wash off the mains.
The position, line by line
| The question | Where it lands |
|---|---|
| Washing a house, its walls, windows, gutters or roof | Permitted at any time, using either a hose fitted with a trigger nozzle or high pressure water cleaning equipment. Building structures are not the restricted category. |
| Washing a driveway, path, concrete or paving | Permitted where cleaning with water is necessary for safety, health, emergency, construction activity including resurfacing, or surface contamination. Hosing a hard surface for any other reason is on the prohibited list. |
| Does a hose need a trigger nozzle | Yes for a hand held hose, unless the hose is supplying high pressure cleaning equipment. Leaving a hose or tap running unattended is prohibited outright. |
| Is there a general exemption for cleaning businesses | No exemption of that kind was found. The named commercial exceptions cover specified horticultural, grounds and water play operations. A pressure cleaning contractor is not on that list and we do not claim to be. |
| What about tank, bore or recycled water | Sydney Water says the guidelines do not apply to recycled water or rainwater, provided the tank is not topped up with drinking water. That is the lawful route for a job with no qualifying reason behind it. |
| Does permission to use water cover the runoff | No. Water use and water pollution are two different rule sets. Being allowed to wash something is not permission for what comes off it to reach a drain. |
Being allowed to use the water is not the same as where it goes
This is the part that catches people, including people in the trade. The water rules and the pollution rules are two separate systems, and clearing the first one does nothing for the second.
Section 120 of the Protection of the Environment Operations Act 1997 makes it an offence to pollute waters, and polluting waters includes causing or permitting them to be polluted. The NSW EPA puts the operating rule in one line: when you are washing anything, the runoff must not enter a stormwater drain.
So on a job with a perfectly good safety reason behind it, the wash water still has to be kept out of the drain. That means blocking the inlets, bunding the kerb, sweeping before wetting, and recovering what pools rather than pushing it down the street.
Breaching the water restrictions
$220 for an individual, $550 for a corporation.
Letting wash water reach the stormwater system
$15,000 for an individual, $30,000 for a corporation.
These are penalty notice amounts for a first offence, in force since 3 April 2024. Councils can issue them at the same amounts. Several council fact sheets still quote figures from the 2010s, and those are out of date.
What all of that means when we quote
The reason for cleaning goes on the job sheet, in words, before anything is switched on, with photographs of the surface it refers to. Where the wash water is captured and where it goes is written down beside it. If the only honest reason is that the owner wants it brighter, we say so and we move the job onto a tank supply or we do not take it.
SafeWork NSW prohibits high pressure water spray on asbestos material. If a surface is fibro or cement sheet, or we think it might be, we stop and say so rather than working it out afterwards.
This page is our own research written plainly, and it is not legal advice. An unusual site, a commercial floor drain or anything connected to a trade waste agreement is a question for Sydney Water, the NSW EPA or the local council before the job, not after it.

What people ask about the water rules
Can I pressure clean my own driveway in Sydney?
Where there is a safety, health, emergency, construction or surface contamination reason for it, yes. A hand held hose needs a trigger nozzle, and a hose supplying high pressure equipment does not. Where the wash is purely to make the surface look newer, drinking water is not the right supply for it, and tank or recycled water is.
Are water restrictions on in Sydney right now?
Sydney Water calls the Water Wise Guidelines mandatory and says they apply every day of the year. When we checked in September 2026 no elevated drought restriction was in force on top of them. The year round guidelines are the ones that decide whether a driveway may be washed.
Is a slippery driveway a good enough reason?
Safety is one of the categories the guideline names, and algae, moss and lichen making a path or a driveway slippery is the commonest one we see. We write the reason on the job sheet with the photographs, so the basis for using water is on the record rather than in somebody's memory.
Do the rules apply to tank or recycled water?
Sydney Water says the guidelines do not apply to recycled water or rainwater, provided the tank is not topped up with drinking water. That is the lawful supply for a job with no qualifying reason behind it. It does not change anything about where the runoff is allowed to go.
Can I wash the house instead?
Yes. Washing building structures, including windows, walls, gutters and roofing, is permitted at any time using a trigger nozzle hose or high pressure cleaning equipment. Buildings are not the restricted category. It is the flat paved ground that is.
What are the penalties?
Two different rule sets, two different numbers. Breaching the water restrictions carries $220 for an individual and $550 for a corporation. Letting wash water reach the stormwater system is a pollution matter, and the penalty notice amounts for a first offence are $15,000 for an individual and $30,000 for a corporation.
Are pressure cleaning contractors exempt?
No exemption of that kind was found. The commercial exceptions named in the guideline cover specified horticultural, grounds and water play operations. A pressure cleaning business is not on that list, and we could not find a source for the idea that this trade is exempt.
