Aqua Nova: first-class sewage treatment systems by Everhard

An alternative to your typical septic tank system, Aqua Nova is regarded as a very safe, reliable, cost-effective and environmentally-friendly system.

Aqua Nova is developed using cutting-edge aeration technology, with the preservation of water in mind. Its design incorporates an advanced filtration system which effectively provides usable recycled wastewater.

Essentially, this revolutionary system converts your premises’ sewage into a water source for use in lawns and gardens.

In South East Queensland, we at Express Wastewater have established ourselves as the go-to source for all sewage needs due to our team of highly trained professionals. With expertise and knowledge in selecting the perfect Aqua Nova sewage treatment system based on your unique requirements, we’ve got you covered.

How does the Aqua Nova septic system work?

The operation of the Aqua Nova system is outlined below:

  1. Primary Treatment: The primary tank collects all of the wastewater that comes from the premises. Once in the tank, the breakdown of solids and fats can begin.
  2. Aerobic Treatment: Once the wastewater is settled it will flow into an aerobic zone which is aerated with a small compressor. This section also has a special bacteria that biodegrades the majority of the solids and fats into a liquid.
  3. Clarification: The water from the aerobic treatment undergoes a final clarification that allows any remaining solids to be pumped back through to the primary tank to start again.
  4. Disinfection: The water from the clarification stage is then disinfected using chlorine. The chlorine concentration is enough to eliminate the bacteria left in the water from the aerobic treatment.
  5. Irrigation: Once the water is disinfected it is then pumped out to an irrigation system as recycled clean water. You can connect this recycled water to sprinklers or even subsurface irrigation.

Sewage treatment systems: septic tanks vs Aqua Nova

Being a direct alternative to a traditional septic tank, it’s only right that you as a consumer can differentiate between these systems.

In septic systems, wastewater is discharged underground, naturally transpiring and posing a risk of pollution to waterways. Furthermore, the operation of septic tanks can be negatively affected by poor soil quality and drainage issues.

Aqua Nova, on the other hand, uses aeration in the wastewater treatment process, enabling safe irrigation back into the soil through gardens and lawns; a factor offering great environmental benefit.

Just like septic systems, Aqua Nova is available in concrete and polymer builds, and is capable of installation by a trained professional on both residential and commercial premises.
