Aqua nova

Pump Wells

1. How does the Aqua Nova® System work?

A standard Aqua Nova® has two tanks. The first tank allows for the separation of solids and greases, while in the second tank the settled wastewater is aerated and clarified. When required, the clarified wastewater is disinfected before being pumped to the irrigation area.

2. Where is the Aqua Nova® System made?

The Aqua Nova® is proudly manufactured in Australia by an Australian Family Owned Company. No royalties are paid to overseas companies and all profits are retained in Australia.

3. Why should I choose a two tank system?

Two tank systems provide a barrier between raw waste water and the treated effluent. This results in a safe, reliable system. The raw waste water and clean recycled water will never mix.

4. What is the resulting water quality?

Aqua Nova® manufactures several different models that achieve different qualities of treated effluent. This provides our customers with a choice that allows our systems to be installed in most locations in Australia. The minimum water quality requirement will have a BOD5 and Suspended Solids of than less than 20mg/L and 30mg/L respectively. Disinfection, filtration and/or membrane systems can be fitted to provide water quality of less than 10mg/L BOD5, 10mg/L Suspended Solids and 10CFU/100ml E.Coli. Nutrient reduction systems are also available

5. Who can service an Aqua Nova® System?

We recommend that all Aqua Nova® systems are serviced by one of our local distributors. Our distributors are trained for servicing Aqua Nova®systems and will work efficiently to keep your wastewater treatment system in tip top condition.

6. Why and how often does the Aqua Nova® need to be serviced?

As with all of your assets, your Aqua Nova® requires servicing and maintenance. A trained service professional will help to keep your system operating at its highest standard. Government regulators require the system to be serviced every 3-months.

7. Can I upgrade an existing septic or wastewater system?

Many houses across Australia use septic tanks to manage their onsite sewage. In recent years we have witnessed many councils around coastal areas trying to improve their local environmental outcomes by having these systems upgraded to aerated wastewater treatment plants. In many instances this can be readily and more affordably done by using the Aqua nova system.

As long as the septic tank has an operating volume of 3000L or more and is of sound condition, then it may be possible to simply have the aeration tank installed immediately behind the septic tank. Persons looking at having a their septic tank upgraded should:

  • get their septic tank assessed for suitability,
  • have a site assessment done by an Aqua nova distributor
  • provide the necessary application to their Local Authority

For more information, please contact us.

8. What kind of cleaning products can I use?

Standard cleaning products usually cause no problem to the operation of an Aqua Nova®. As the system is biological, owners must use of bleaches and disinfectants sparingly. For a full list of recommendations, please download our Home Owner’s manual, or contact us.

9. Can I use the water from the Aqua Nova® System in my home?

Treated effluent can only be used to irrigate the area specified by planning documents.

10. How loud is the system?

When operating and maintained correctly, the noise that comes from an Aqua Nova® is barely noticeable.

11. Does the Aqua Nova® System smell?

Systems that are operated as per the Owner’s Manual and are appropriately maintained will not smell.

12. Can I turn off my system?

The system should not be turned off at any time. So long as the system is on, you can have extended periods of non-usage without causing any disruption to the system.

13. Can I hide the lids underground?

No. Lids cannot be hidden underground as they are used to provide safe access to the system during maintenance.

14. My new home has an Aqua Nova® system, what do I do?

Simply contact us. We are happy to find a local distributor to get in contact with you to assist with any queries you have.

5. Is council approval required to install a pump well?

In some areas of Australia, it may also be necessary to attain council approval prior to installing a Pump Well. Persons installing our Pump Wells must ensure that all necessary precautions are made to prevent hydraulic uplift and ensure adequate space is available for pump and tank maintenance.
