Nubian Greywater Systems

Nubian greywater systems treat your used greywater converting it to clean healthy water that can be used for non-potable purposes such as flushing toilets and irrigating your gardens and lawns.

What is Greywater?

Greywater is water that has been used in plumbing fixtures such as a washing machine and shower. This water is fairly easy to treat and return to a useable state.

The opposite of greywater is Blackwater which consists of water that has been flushed down the toilet or that is used in your kitchen sink. Blackwater does not divert to a Nubian system.

Who are Nubian and are they still around?

Nubian was a company who unfortunately is no longer in business. Unfortunately, this means if you’re after a new system, you’re out of luck unless you can find someone selling a second hand one.

That said, if you have an existing Nubian greywater treatment system installed you are one of the lucky ones. These systems are extremely reliable, low cost to run and maintain and can create many thousands of litres of high-quality water that would otherwise be poured down the drain. A Nubian greywater treatment system not only saves you money but also is great for the environment as your re-creating one of our most precious resources, quality water.

I heard you can no longer get spare parts for Nubian systems or that restoring them costs too much money?

This is one of the most common misconceptions we hear from customers and it’s is simply not true. This rumour is generally spread by plumbers who are unaware of the service requirements and components that they operate with.

The single-component that could become problematic in the future as it is no longer manufactured is the PC board, however, this part is fairly robust, there is an abundance of stock and the experts in the field are able to repair the existing boards. There is no point in the short to medium term that we believe this will become an issue.

Nubian Systems in Canberra Strata Buildings

One of the biggest wastes we see is in large strata buildings around the ACT and Canberra surrounds. Many of these buildings have Nubian systems installed that have simply been switched off at the power point, normally by a plumber that has no idea about what the device is or what its service requirements are. By switching it off, all of the water then diverts to the sewage and disappears for good. The Strata Managers and Executive Committees are none the wiser that they have this excellent infrastructure installed and that it requires some basic ongoing servicing.

We have even come across some systems that had never been properly commissioned and that have never generated even a single litre of clean non-potable water.

The infrastructure costs for installing a greywater system is huge. Where large units have been installed the Nubian alone could have been over $100,000 let alone the infrastructure costs at the time of building that allowed for the plumbers to install a two-pipe system (black and grey water) so that the greywater could be diverted to the treatment plant.

How do you know if your system is in operation?

Ask your Strata Manager who the Nubian Service Agent is. If it is not being regularly serviced then you can be certain that it is not operational.

To the best of our knowledge, we are the only Canberra plumbing contractors who service and maintain these systems. I’ll happily remove this last statement if I hear of another Canberra plumbing company who services these systems.
