Bach and cabin wastewater package
WCTNZ® | Bionova Cabin Zero-Discharge Bach Wastewater Package
A compact bach and cabin wastewater package built around the Bionova Cabin for small accommodation spaces, baches, cabins and off-grid getaway projects.
The package uses the Bionova Cabin for the all-in-one toilet-waste pathway and the GreyFlow™ PS-AG range for a more flexible pumped greywater pathway where hilly ground or variable visitor numbers need to be considered.

Build the package from the products below
This Bionova Cabin bach wastewater package is designed for compact baches, cabins, glamping units and off-grid getaway projects where an all-in-one toilet-waste pathway is preferred but the greywater system still needs stronger site flexibility.
This is a situation-based grouped package rather than a fixed discount bundle. Select the required products and options below so the final package matches the site, use level and installation pathway.
System pathway
What this package is designed to cover
Toilet-waste pathway
Bionova Cabin all-in-one, self-contained toilet-waste pathway for compact accommodation settings.
Grease management
Small Passway™ grease trap / grease interceptor can provide kitchen wastewater protection where kitchen wastewater is included in the site pathway.
Greywater pathway
GreyFlow™ PS-AG range selected to suit site slope, pumping head, land-application design and occasional visitor loading.
Land application
GreyFlow™ dripper field components selected to suit the site and expected use.
Package components
Recommended core products to select below
Bionova Cabin
Compact all-in-one self-contained toilet-waste pathway for small baches, cabins, glamping units and off-grid getaway spaces.
Small Passway™ grease trap
Small grease separation unit for kitchen-line protection where kitchen wastewater joins the selected greywater or wastewater pathway.
GreyFlow™ PS-AG range
Select PS-AG-M1, PS-AG-M3 or PS-AG-M4 according to flow, head, terrain and use level. This suits hilly sites and variable visitor numbers better than assuming a single small pump pathway.
GreyFlow™ dripper field
Subsurface land-application pathway for suitable greywater, selected to match site conditions.
Why these products are grouped
A practical starting point for the situation
- Creates a compact package pathway for baches, cabins and glamping accommodation.
- Uses the Bionova Cabin as the toilet-waste component while still giving the greywater pathway enough pump flexibility.
- Recognises that baches and cabins can see visitor spikes and hilly ground, so the GreyFlow™ PS-AG range is a better technical fit.
- Allows the final PS-AG model and field size to be matched to the site.
Site and consent context
Final suitability remains project-specific
Zero-discharge wording: The Bionova Cabin is positioned as an all-in-one self-contained toilet-waste pathway. Shower, bathroom, laundry and kitchen wastewater still require a separate greywater, grease-management or wastewater pathway suitable for the site.
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 bach or cabin wastewater pathway.
