Why these products are grouped
A practical starting point for the situation
- Built around a serious residential composting toilet system rather than a small portable or chattel-style product.
- Uses GreyFlow™ PRO for the full-home greywater treatment pathway rather than a small diversion-only product.
- Separates toilet waste from greywater design for a more robust off-grid home pathway.
- Supports council, designer and wastewater professional review for full off-grid home projects.
Site and consent context
Final suitability remains project-specific
Project pathway note: This package is normally reviewed as a project pathway rather than a fixed kit. Final system selection depends on user load, building layout, subfloor access, site levels, greywater source, soil conditions, land-application area and council requirements.
NZ Building Code and council review: WCTNZ® can provide product information, technical documentation and consent-support information for customers, designers, builders, plumbers and wastewater professionals reviewing a full off-grid home wastewater pathway.
