WaterMark certification is the mandatory Australian approval that shows a plumbing product has been independently tested and licensed for use in a plumbing or drainage installation. If a product sits on the WaterMark Schedule of Products, it is illegal to install it in Australia without that certification. For a pump station, the certification attaches to the individual plumbing components inside the package, not to the whole unit as one item, and that distinction is where most of the confusion starts.
Here is what it actually means when you are standing in front of a $3,000 purchase.
What WaterMark certification actually is
WaterMark is a product certification scheme run by the Australian Building Codes Board. A manufacturer submits a product, an accredited certifying body tests it against the relevant Australian Standard, and if it passes, the product gets a licence number and goes on the public WaterMark Product Database.
The certifying bodies are independent. They are accredited by JAS-ANZ, and they are the ones who issue and police the licence, not the ABCB and definitely not the manufacturer. That matters, because the certificate you get sent should name the certifying body and carry a licence number you can look up yourself.
The mark itself is the WaterMark logo plus a licence number, moulded or printed on the product. A logo with no number next to it is not a certification. It is a picture.
Why it is not optional
WaterMark compliance is law, not a quality badge. The Plumbing Code of Australia, which is Volume Three of the National Construction Code, requires that any product listed on the WaterMark Schedule of Products be certified before it goes into a plumbing installation. Each state and territory plumbing regulator adopts that requirement.
What that means in practice, in order of how badly it stings:
- Your licensed plumber can refuse to install it, and a good one will
- The water authority can refuse to approve the connection
- You can be ordered to remove and replace non-compliant work at your own cost
- An insurer can take a very close interest after a failure
Nobody wants that conversation after the concrete has gone down.
Level 1 and Level 2 certification
The scheme has two evidence levels, set by how much damage the product can do if it fails. Level 1 is the higher risk tier and carries ongoing factory surveillance and audit testing. Level 2 covers lower risk products with a lighter evidence burden.
| Level | Applies to | Ongoing obligations |
|---|---|---|
| Level 1 | Higher risk products, where failure affects health, safety or the potable supply | Initial type testing plus ongoing factory audits and periodic retesting |
| Level 2 | Lower risk products, where failure is contained and obvious | Type testing and a documented quality system, lighter surveillance |
You do not need to memorise which tier a fitting sits in. What you need is the licence number, because the database tells you the level, the standard, the scope and the expiry date in one screen.
What WaterMark covers on a packaged pump station
The certified parts of a packaged pump station are the plumbing components in the wastewater path, not the assembly as a whole. A packaged station is a kit: a poly tank, a pump, discharge pipework, a non-return valve, an isolation valve, a vent, an access cover and usually a level control and alarm. Those components are certified individually where the Schedule requires it.
The tank is not the certified part people assume it is
A poly collection tank is a holding vessel, not a plumbing fitting in the sense the Schedule uses. The parts that carry a WaterMark obligation are the ones in the sanitary drainage line: valves, fittings, pipe and connections. So a supplier saying "the station is WaterMark certified" is being loose with language. Ask which components, under which licence.
Ask for the licence number, not the logo
A licence number is checkable in about a minute and a logo is not. Request the certificate for the components in the discharge assembly, and confirm the model on the certificate is the model in the box. Certificates get reused across a product family, and the one you are sent is sometimes for the sibling model that was tested, not the one you bought.
How to check a WaterMark licence in four minutes
Search the WaterMark Product Database on the ABCB website using the licence number from the certificate. It is free, public and takes longer to find your reading glasses than to run the search. Four things to confirm once you have the record open:
- Status is current. Licences expire and licences get suspended. An expired licence is not a licence.
- The model matches. Exactly. Not the range, the model.
- The scope covers your use. A fitting certified for cold water is not certified for sanitary drainage.
- The licence holder is the manufacturer or the importer you are buying from. A licence belongs to a party, not to a shape of product.
If a seller will not give you a number, that is your answer.
What WaterMark does not cover
WaterMark says nothing about the electrical side, the site approval or the structural rating of a pump station, and all three will stop your install just as hard. Three separate approvals, three separate trades.
Electrical compliance
A pump station is a 240V appliance in a wet pit and it needs a licensed electrician. The pump, the level controller and the alarm all sit under electrical rules and IP ratings, not the plumbing scheme. The plumber does the pipework, the sparky does the power, and neither of them signs off the other's work.
Water authority approval
Every water authority runs its own rules for pump-out connections to their sewer, and those rules vary by state and sometimes by suburb. Some maintain their own approved products lists on top of WaterMark. Your licensed plumber handles this as part of the connection application, and they should be doing it before you order, not after.
Access cover load class
Access cover load rating is a structural spec, graded Class A through G, and WaterMark has nothing to do with it. Pedestrian rated covers come standard on most packages. If the pit ends up under a driveway, and plans change during a build more often than anyone admits, you need a load rated cover instead. Cheap to specify at order, expensive once there is concrete over it.
Where buyers get caught
Four patterns come up over and over, and all four are avoidable.
Grey imports off a marketplace. A pump landed direct from overseas at half the price is usually half the price because nobody paid for testing. There is no Australian licence holder to chase and no certificate to produce.
A certificate for the wrong model. Common, and usually not malicious. The tested model and the sold model drifted apart across a product update. Check the model string character by character.
An expired licence nobody noticed. Licences run on a term. A supplier who has not re-registered still has a beautiful looking PDF sitting on their server.
Assuming the package covers everything. Buyers ask whether the station is certified, get a yes, and stop. The valve that fails the inspection is usually the one somebody swapped on site.
What we supply and what comes with it
Every packaged station Waternex sells comes pre-assembled with the discharge pipework and valves already fitted by the manufacturer, which is the point of buying a package rather than a bin and a box of parts. Ask us for the certification paperwork on any of them and we will send what the manufacturer holds.
| Station | Tank | Typical use | Price |
|---|---|---|---|
| Kwikflo 250L Sewer Pump Station | 250L | Granny flat, basement bathroom, garbage room | $3,199 |
| REEFE RGM055A 250L Sewer Pump Station | 250L | Same again, compact grinder plus high level alarm | $3,349 |
| REEFE 250L QubeX Series | 250L | Heavier duty grinder for tougher solids | $3,499 |

Prices are Waternex list prices in AUD including GST, current as of August 2026. The 250L Kwikflo is priced by state.
Stormwater is a separate path with its own products, because a drainage pump and a grinder pump are not interchangeable. The Kwikflo 250L Stormwater Pump Station is $2,607, and the smaller REEFE Stormwater Pit and Pump starts at $799. If you are not sure which side of that line you are on, read Grinder Pump vs Drainage Pump first.

Frequently asked questions
Is WaterMark certification mandatory for a pump station in Australia?
Yes for any component of the station that appears on the WaterMark Schedule of Products, which covers the valves, fittings and pipework in the wastewater path. The poly tank itself is not certified in the same way. Your licensed plumber confirms what your state regulator and water authority require for your specific install.
How do I check if a pump is WaterMark certified?
Search the licence number in the WaterMark Product Database on the ABCB website. It is free and public. Confirm the status is current, the model matches exactly, the scope covers sanitary drainage, and the licence holder is the party you are buying from.
What happens if I install a pump station without WaterMark certified components?
Your plumber can refuse the job, the water authority can refuse to approve the connection, and you can be directed to replace the non-compliant work at your own cost. Insurance also gets complicated after a failure involving uncertified plumbing products.
Does WaterMark cover the electrical parts of a pump station?
No. WaterMark is a plumbing product scheme only. The pump motor, level controller and alarm sit under Australian electrical rules and need a licensed electrician. Plumbing certification and electrical compliance are two separate approvals.
Is a cheap imported sewage pump from an online marketplace legal to install?
Usually not, if it lacks a current WaterMark licence held by an Australian supplier. Marketplace imports are cheap largely because nobody paid for certification, and there is no licence holder to produce a certificate when the inspector asks.
What is the difference between WaterMark Level 1 and Level 2?
Level 1 applies to higher risk products and requires ongoing factory audits and periodic retesting on top of the initial type testing. Level 2 applies to lower risk products with type testing and a documented quality system. The database record tells you which level a product holds.
