The rules on pressure washing in Pakenham.
Water use rules, the EPA duty, where your run-off actually ends up, and who wears it if something goes down the drain that should not have. Not complicated, but worth knowing before you hand over the job.
The pressure washer is the legal option, not the problem.
People often assume a pressure washer is the water-hungry choice and a garden hose is the innocent one. It is the other way around. Melbourne’s permanent water use rules apply across the South East Water supply area, which covers Pakenham, year round, whether or not there are drought restrictions on top. Under those rules, hard surfaces such as driveways, paths and paving may only be cleaned with a high pressure cleaning device or a bucket, and only for a defined reason: health and safety, preparing the surface for painting or renovation, or dealing with an accident or a spill.
Read that carefully, because two things fall out of it. First, standing there with a running garden hose sluicing the driveway because it looks a bit dirty is the thing the rules are actually aimed at. Second, a pressure washer is explicitly the permitted device, and it uses dramatically less water. A garden hose runs somewhere around 15 to 18 litres a minute. A professional unit does the same work at roughly 8 to 12 litres a minute, and does it in a fraction of the time because the cleaning is done by pressure and detergent rather than volume. A slippery, moss-covered path is also a straightforward health and safety reason under the rules, which covers most of what people ring us about.
Your kerb drain runs to Western Port.
This is the part almost nobody knows, and it is the whole reason the rest of this page exists. The stormwater pit at your kerb is not plumbed to a treatment plant. It is a pipe to a creek. In Pakenham that means Toomuc Creek, Deep Creek or Cardinia Creek, depending on which side of town you are on, and from there into Western Port, a Ramsar listed wetland of international significance and one of the most closely watched catchments in Victoria. That is by design, not by accident: the stormwater system covered by AS/NZS 3500.3, the plumbing and drainage standard for stormwater, exists to move rainwater off your property and away, quickly. It has no treatment step anywhere in it, because rain is all it was ever meant to carry.
So whatever leaves your driveway and reaches that pit, detergent, engine oil, brake dust, diesel, sediment, arrives in the creek essentially unchanged. That is not a technicality. A single driveway’s worth of accumulated sump oil, flushed straight to the kerb, is a visible slick in a waterway that supports migratory shorebirds. Sewer and stormwater are two entirely separate systems, and it is the sewer, the one that goes to treatment, that your laundry water uses. The drive does not have that luxury.
The General Environmental Duty, and why it is your problem too.
Since 1 July 2021 the Environment Protection Act 2017 has carried a General Environmental Duty. In plain terms, anyone conducting an activity that could harm human health or the environment must reduce that risk so far as reasonably practicable. It is a proactive duty, not a rule you only breach after something goes visibly wrong, and critically it attaches to the person conducting the activity, which can mean the property owner or site occupier as well as the contractor swinging the wand.
What is reasonably practicable scales with the job. For a clean water rinse of a domestic driveway with a biodegradable detergent, diverting the run-off onto lawn or garden so it soaks into the soil is genuinely enough, and the soil does the filtering. For a driveway with real oil in it, or any commercial site, it means covering the stormwater pit, bunding the wash area, recovering the water with a wet vacuum and disposing of it lawfully. Discharging recovered wash water to sewer is not automatically free either. Trade waste of that kind needs an agreement with South East Water. Cutting those steps saves the operator an hour and shifts the exposure onto the site.
Do you need a permit from Cardinia Shire? Almost certainly not.
For cleaning your own house, roof, driveway or paths in Pakenham, no. Cardinia Shire Council requires no permit for it, and there is no operator licence for pressure washing in Victoria, which is precisely why the checks in our how to choose a pressure washer guide matter so much. Anyone can buy a machine and print a card.
Permits appear only in narrow commercial situations, and they are about occupying public land rather than about washing. A shopfront clean along the Main Street or Princes Highway frontage that needs scaffolding, a hoarding or plant standing on a council footpath needs council consent for that occupation. Same for anything that closes part of a public car park. Height work brings its own separate obligations under the Victorian Occupational Health and Safety Regulations 2017, which require proper fall prevention for roof work, and that applies to the contractor on any roof clean regardless of whether council has any interest in it.
What compliant work looks like, and what it costs.
Here is the honest version: on a normal domestic driveway clean at $180 to $320, compliance costs almost nothing. It is a biodegradable detergent and a bit of thought about diverting the run-off to the garden strip instead of the kerb. That is why a cheap operator being sloppy about it is doubly annoying: they are not even saving money, they just cannot be bothered.
Where it does cost is oil and commercial. Bunding, drain covers, a wet vacuum and lawful disposal add time and equipment to a job, and that is a real part of why commercial work sits at $1.50 to $4 per square metre rather than the dollar-something someone might quote you off the back of a ute. That is also why an oily driveway is quoted above a plain one, which we break down on our oil stain removal page. The full breakdown is on our pricing guide.
Worked example: a Pakenham workshop forecourt.
A mechanical workshop with a 220 square metre concrete forecourt off the Princes Highway service road, with years of sump oil and diesel drips. The compliant job is: cover and seal the two stormwater pits, bund the low side, degrease and hot wash in sections, recover the water with a wet vac into an IBC, and dispose of it through a licensed waste route rather than the kerb. At around $3 per square metre that is roughly $660 for the wash, plus the recovery and disposal. A non-compliant operator will quote $350 and send the lot down the pit into Toomuc Creek. The $310 saving looks good right up until an EPA officer follows the slick back to the forecourt, at which point the occupier is the one explaining it.
Rules and run-off: your questions.
Am I allowed to pressure wash my driveway in Pakenham?
Yes, and in fact a pressure washer is the approved method. Melbourne's permanent water use rules, which apply year round through South East Water regardless of whether there are drought restrictions in force, say hard surfaces such as driveways, paths and paving may only be cleaned with a high pressure cleaning device or a bucket, and only for specific reasons: health and safety, preparing a surface for painting or renovation, or dealing with an accident or spill. Hosing the driveway down with a running garden hose to freshen it up is what the rules actually prohibit. The pressure washer is the compliant tool.
Do I need a council permit to pressure wash in Pakenham?
No. Cardinia Shire Council does not require a permit for cleaning your own house, roof, driveway or paths, and there is no licence required to operate as a pressure washing contractor in Victoria. Permits only come into it in narrow commercial situations, for example if a shopfront clean needs scaffolding or a hoarding on a council footpath, or if plant needs to occupy a road reserve or a public car park. That is a consent for occupying public land, not for the washing itself.
Where does pressure washing run-off go in Pakenham?
Straight to a creek, untreated. This is the part most people do not realise. The stormwater drain at your kerb is not connected to a treatment plant. In Pakenham it discharges to Toomuc Creek, Deep Creek or Cardinia Creek, and from there into Western Port, which is a Ramsar listed wetland of international significance. Anything that goes down that drain, detergent, oil, sediment, diesel from a driveway, ends up in the creek system essentially as it left your property.
What does the EPA require for pressure washing run-off?
Under the Victorian Environment Protection Act 2017 there is a General Environmental Duty, in force since 1 July 2021, which requires anyone conducting an activity that could harm human health or the environment to reduce that risk so far as reasonably practicable. It applies to the property owner as well as the contractor. In practice, for a clean water rinse on a domestic driveway, diverting run-off to lawn or garden so it soaks away is enough. For oily driveways and commercial sites it means covering the drain, bunding the area, recovering the water with a wet vacuum and disposing of it lawfully rather than letting it reach the kerb.
Can I get fined for pressure washing run-off going down the drain?
It is possible, and it is worth understanding that the liability does not automatically sit with the contractor. Because the General Environmental Duty applies to the person conducting the activity, and because the pollution is leaving your land, an EPA notice or a Cardinia Shire local law issue over a visible oil slick heading into a stormwater pit can land on the property owner or the site occupier. That is exactly why we ask how a contractor handles run-off before they start, and why on any oily or commercial job we contain and recover it rather than letting it run.
