Nestled just north of Auckland, this off-grid passive solar home was designed with sustainability at its core — using natural materials, renewable energy, and a low-impact footprint. The owners wanted a wastewater system that matched their eco-conscious lifestyle: power-free, low-maintenance, and fully compatible with their solar setup.

The solution? A NaturalFlow 8000P combined with the Wormorator — a natural, power-free wastewater treatment system that fits seamlessly into an off-grid lifestyle.

Why This System Works Perfectly for Passive Solar Homes

• Completely Power-Free – no pumps, no electricity, no extra load on the solar system.

• Low Maintenance – natural processes reduce servicing needs dramatically.

• Eco-Friendly Filtration – utilises worms, bacteria, and filtration to process waste naturally.

• Sustainable Design – blends with the property’s ethos of living in harmony with the environment.

• Long-Term Value – designed for decades of reliable service with minimal running costs.

Implementation Process

1. Consultation & design
   Our team worked with the homeowners to ensure the system would meet daily household needs while aligning with the passive solar design.

2. Installation of NaturalFlow 8000P
   The modular 8000P unit was installed as the main wastewater treatment system, using gravity-fed operation to move water without power.

3. Integration of the wormorator
   The Wormorator was added to naturally process household waste through vermiculture, producing healthy, filtered effluent for safe dispersal.

4. Finishing with natural landscaping
   The system was landscaped with native plants, enhancing absorption and further supporting the property’s biodiversity goals.
