Communities

With three decades of experience, Innoflow works with councils and developers on decentralised wastewater schemes for unsewered communities across New Zealand.

In towns like Piopio, failing septic tanks pose risks to public health and the environment, especially with high rainfall and poorly drained soils.

Prelos™ liquid-only sewers convey primary treated liquid to AdvanTex® plants, benefiting developers, councils, and homeowners.

Our flagship project is Jack’s Point in Queenstown, planned in 2002 for 1,400 homes.

Key benefits of our community systems:

  • Modular design for fast installation, minimal disruption, and easy retrofit of existing septic tanks

  • Flexible expansion for growing communities and staged developments

  • Resilient to fluctuating loads, ideal for transient workforces and seasonal populations

  • Removes maintenance responsibility from individual homeowners, ensuring high-quality effluent, nutrient/pathogen reduction, and land irrigation reuse

  • Visually unobtrusive, quiet, low operating costs, and meets regulatory and public health requirements

We have installed over 70 Prelos schemes in New Zealand and hundreds more worldwide, including Australia and the US.

Our technology for community treatment plants

After effluent is collected from each house via gravity (STEG) or pumped (Prelos/STEP), Advanced Secondary Treatment is usually provided by AX100 pods or, for sites with limited space, the AX-Max treatment plant, which combines primary treatment, recirculation, and discharge in a single module.

AX100 pod systems can be installed in multi-pod arrays to handle effluent from an entire community of on-site Prelos™ tanks or used in a centralised plant for wastewater from a standard gravity sewer system.

AX-Max units are a turnkey solution for remote sites and communities. Fully assembled, easily transported, and scalable by adding units, they provide treatment to suit the overall flow requirements of the project.
